Ok the printer has now out of the blue started coming up with errors saying all the print cartridges are missing, tray 1 is missing does anyone know what causes this?


Re: Xerox Phaser 7700 by marty5261 (10/19/04 4:44 PM) reply + / -
Check the left side door assy where the fuser is located, on the door near teh top towards the rear of teh printer there should be a piece that sticks out which will close a interlock swith when closed. It may be black or same color as teh covers. If this is broken off it will cause the problem you describe. Easy way to check is to use a screwdriver to push in on the interlock to close it and see if the problem goes away.


Re: Xerox Phaser 7700 by Jason (10/20/04 4:42 AM) reply + / -
Nope I checked. It is there and I even tried pushing that switch in but nothing happened


Re: Re: Xerox Phaser 7700 by Anonymous (11/28/05 6:18 AM) reply + / -
The side door under the MPT tray has a little plastic friction latch. Same color as door and towards the back on top. It has a tendancy to bent up and restrict the full closure of the door. bend it staight and back down. If there is a lower tray unit, disconnect it from the printer and power it up. See if it comes up then. Those errors are the diags rolling through possible problems, but a door open is the likely cause.

We have been using the Xerox Phaser 7700DN in our print for pay bureau since 2003. It has performed satisfactorily but yesterday 05/05/2006 started showing a yellow band just outside the image area on the side nearest the front service door. This has happened several times and we usually fix it by taking out the yellow developer unit and sifting the developer to clear any foreign particles. However, this time, after putting everything back and powering up, the printer started showing "Error 30 - Accumulator Belt Home position took too long"
Has anyone come accross this Error 30 and what fixed it?

"Error 30" was caused by a faulty belt. After replacing the belt evrything works fine.

I am getting a laser Error 10 and cartridges are missing error
problem is intermittent seems i can only print 1-2 pages before i get the error , somtimes will print several hours before failure.
Thanks for any help

This was EXACTLY our problem with our Xerox 7700, cycling through the print cartridges are missing, trays missing, etc. I bent the tab down some, closed it all the way, and was the hero of the day around here. Thanks to whomever suggested this fix. If the Admin asst. had called in the Xerox tech, it would have been at least $300 or more.

Gary:

Did you get a resolution to this problem? Our 7700 does exactly the same thing (Error 10), and the service company is quoting us $1,500+ to replace the laser unit...which DOES work...intermittently. I also get the weird "cartridge missing" errors and so one, so I suspect the laser is not really the problem.




Re: Xerox Phaser 7700 by XPhaserTek (9/9/07 6:30 PM) reply + / -
In most cases when a printer cycles thru all print cartridges missing it`s usually the door below the MPT not being properly closed. A error 10 can be caused by a poor connection of the laser to the engine board or a bad laser or a bad engine board.
Print out the Service Usage Profile and check the engine error log
to confirm the error code. Most of the time lasers fail with a error 11. If you have some of these it`s a good bet the laser will
need to be replaced sooner or later and it`s an expensive part.
The printer`s usefull life is about 500,000 pages, so if you are getting close to this then maybe it`s not worth repairing, also Xerox will eventually stop supporting it probably in a couple of years...

Just my 2 cents.


Re: Re: Xerox Phaser 7700 by Anonymous (9/9/07 7:17 PM) reply + / -
Thanks for the suggestions. This printer only has about 31,000 pages on it. Even so, I hate to spend thousands to fix it since its already two generations behind. I'll check the engine error log and see where it takes me.

The scanner fixed the problem , we tried the logic board first but it ended up the scanner had to be replaced $1200 part plus labor

Anytime a page with substantial black is printed, fuser jams. With other images, thin black lines will repeat across the page. Black print feels raised and small black areas break away. Changed toner. Fuser is new. Had same problem with old one. Tried different paper. Other colors fuse perfectly. Is it possible the old black toner is the problem and it hasn't been flushed out yet? Is there a "flushing" procedure? Stumped!


Re: Xerox Phaser 7700 by theprinterfixer (10/24/07 4:32 PM) reply + / -
The onlt 2 things that will cause your problem are the fuser or the paper. the paper must be laser paper. Not multipurpose just laser paper. Make sure the printer knows what paper you are using, there is a guide inside the tray telling you what to set the different weights for. This needs to be correct as it changes the fuser settings. There is a built in cleaning cycle for cleaning the fuser. In the troubleshooting menu look for improve print quality, remove print smears. This heats up the fuser and shoots some blank pages through it to clean off the rollers. If you are getting black lines on your blank pages as well you may just need to clean the black laser window. There is a cleaning tool in the front cover with instructions on how to use it.


Re: Re: Xerox Phaser 7700 by tanxrus (10/24/07 9:19 PM) reply + / -
Thanks for the quick comeback.

Just ran the fuser cleaning cycle and 5 pages went thru fine -came out pretty clean.Then using the same lettersize paper as always,and set to the correct paper type, , printed a fine output of a xerox support page on Safari. Thought it was fixed! Then I went to my Mail and printed an email. The header printed perfectly but all of the body is poorly fused, feels raised!
Then I ran a tabloid size , 2 sided newsletter that, when run a few days ago, ran great. That tabloid paper never ever jammed. Now it crashed totally in the fuser!

Since the fuser is new and the problem is now worse and some files print well and others don't,(some even print fine at one part and poor on the other part of the same page) I do think it is software related.

The black lines I mentioned are ghosts of the vertical portions of a thin border line on the edge of the page, not from a dirty laser.

It just seems that only the BLACK output is the problem. The blacker the output the more it sticks the paper to the fuser, and what does get thru is poorly fused. If it really was the paper, wouldn't all the colors do it? Hope I can straighten this out soon!


Re: Xerox Phaser 7700 by theprinterfixer (10/25/07 3:24 AM) reply + / -
If you look in the fuser door you will see a exit roller. It is in the door side not the fuser side and when you almost close the door you will see it lines up just above the fuser. It has about 4 black rollers on it that over time get really spongy. They can also get to the point where they break down and melt, that may be what you are seeing on your prints, melted rubber. If so you just need to order a exit roller assembly. If this is ok and you are definately using laser paper, then you must have a bad fuser. If it's less than 90 days old and less than 50% used call your supplier and get a free replacement.


Re: Xerox Phaser 7700 by Tanxrus (10/25/07 5:12 AM) reply + / -
Rollers are fine. Just printed a text docuement three ways- As .rtf, .html, and word format and all 8 pages of prints are PERFECT(except crap on the back of the first page- from last crash .Then printed 3 invoices from MYOB, 1 directly, 1 as pdg, 1 as jpeg-- ALL CRAP poor fusion, flakes, ghosting, etc. Then tried the original .rtf-againPERFECT.

Now get this. I pasted my logo (basically a solid black rectangle 5/8" x 1 1/2 " with white design and white text) to the .rtf document right in the very middle- print- all text perfect-but logo blotchy, poorly fused, and a rubber stamp ghost of the logo 1 7/8" to left, half off the page. Then put three logos down the right side-print- crash fuser again.

I had this problem long ago with 1 file. Can't rember if I changed it's format or used a different printer.

BTW- Same problem printing checks w/ quicken.




Re: Xerox Phaser 7700 by theprinterfixer (11/4/07 11:53 AM) reply + / -
If you are getting the "rubber stamp ghost" you probably have a defective print cartridge. If the repeated image is black then swap the black and magenta print cartridges and see if the problem goes with the print cartridge. If it does, print out the consummables page and see how old the defective cartridge is. If it's less than 90 days old and has more than 50% life remaining you can get a free replacement from xerox.


Re: Xerox Phaser 7700 by Tanxrus (11/4/07 2:34 PM) reply + / -
Swap K and M carts. Turn on printer. Prints a stunningly perfect startup page. Print a pdf with preview. Paper crashes in the fuser. THERE IS NOTHING WRONG with the print engine. This has to be a software or firmware problem within the printer!


Re: Xerox Phaser 7700 by theprinterfixer (11/4/07 3:08 PM) reply + / -
I go back to my original diagnosis. It's either the paper or the fuser. You said it was letter size paper, what weight is it and are you sure it's laser paper? Post the paper info off the package it came from.


Re: Xerox Phaser 7700 by Tanxrus (11/4/07 7:12 PM) reply + / -
Can you please explain why some applications (and the printable page menu)print fine ALL OF THE TIME and some always mess up?I use the same batch of paper from before the problem: Staples 11x17 20# laser and sam's club 20#multipurpose letter size.


Re: Xerox Phaser 7700 by theprinterfixer (11/5/07 6:00 PM) reply + / -
I'm not sure which of these words you don't understand so i'll type slowly. You cannot use multipurpose paper in Xerox laser printers. Multipurpose paper has a clay content so the ink jet printers can print on it. The clay clogs the fuser.


Re: Re: Xerox Phaser 7700 by Anonymous (11/7/07 6:12 AM) reply + / -
Obviously, this user has used multipurpose paper in the past with no problems. I have HUNDREDS of customers who use multipurpose paper in ALL their laser machines with little to no ill effects aside from what you would expect from regular wear and tear.

There is NOTHING special, I.E. varying in construction, about the parts used in Xerox Fusers compared to other laser printers. If you have any experience in the field, you would know that while the designs may differ and the engines may differ, the same materiels and concepts are used across the board - example being fuser pressure rollers of silicon rubber, pickup/feed rollers made of a gum rubber materiel, etc. The difference in the hardware side of printers is mainly quality control of these components. You have posted several "stuart woods"-esque answers here...from what I have experienced, newbie technicians are quick to cry "media (paper) problem" or "bad motor" when up against a new challenge!

"theprinterfixer", did you read the user reporting that the printer jams and prints fail with the same application? That negatates the possibility of the problem being paper - if it were a media (paper) issue, the problem would be consistant across ALL print jobs.

From the information provided, I would check your software - does it use PCL (and what version) or PJL or PostScript? Perhaps it needs a firmware update or the application software has to be configued differently. I'd have an IT person who knows software and printers take a look and determine if its a software problem, especially when you mention PDFs and Quicken - both applications that sometimes print directly to the printer and override some paper size settings. I'd look into the software side of things before spending ANY more money on this printer.

Mind you, I only glanced over the forum, and had to shoot the hip when I see someone repeatedly telling you its paper or fuser problem. Initial analysis suggests its software...but, as we all know only so much can be done without getting our hands on it!

Good Luck!

Corsair: THANKYOU! Finally someone who understands my plight! I thank The printerfixer for his/her help and responses even if he occasionally types slowly!

I printed a bunch of stuff from a PC laptop and got fine results BUT when I printed a photo that had been emailed to the PC from Iphoto on the mac, guess what? KEE-RASH!

Xerox has a firmware update but it runs on OS9 and I cannot run it on the MacBookPro and can't figure out how to run it on an older IMac.

My son (an IT major) will do it when he comes home from college for the holidays, but I am not sure even this will fix it. SO, for a measly $1150 I am having another 7700 delivered to my door! It has a 41,000 pagecount and mine has a 101,000 pagecount. All of my consumables will be compatible. IF he can fix it then I will have a fine spare or a his/hers pair. If not, I will have a boat anchor!


Re: Re: Re: Xerox Phaser 7700 by theprinterfixer (11/7/07 1:43 PM) reply + / -
Yes I guess you did just glance at the forum otherwise you may have noticed that regardless of what software application he was using, "the paper always jammed in the fuser". Maybe i'm mistaken because, as a newbe who's only been working on printers for 38 years, I don't know any application that would cause this. If you want to offer some constructive advise do so. I guess you don't have any experience with Xerox printers otherwise you would know their laser printers will not handle multipurpose paper. I'm only certified on 42 of their products so i'm just guessing.


Re: Re: Re: Re: Xerox Phaser 7700 by Anonymous (11/8/07 6:55 AM) reply + / -
printerfixer,

No need to start a pissing contest or pull out your certification book. I've got plenty of experience, and I've seen Xerox lasers work perfectly fine on multipurpose paper - i've got reams of test pages from all of our depot work that will prove it. We all know the Xerox line, but media has to be taken on a case by case basis - and I'm sure if this user bought tabliod size its not run of the mill multi paper.

Trying not to get personal here and I'm sorry if I sniped in the previous post, but I've a bad habit of not editing myself, i'll be more cautious here. You'll find, however, there aren't a lot of printer techs who know software and how operating systems ( ESPECIALLY MACINTOSH as in this case) jive with the mechanical workings of a printer system. I just happen to be one of those that do. Graphics software can be very detailed in how it commands the printer to do things, and many of these software settings are invisible to the user and the technician!

I could swear the user reported some prints would go fine from some applications - and that he replaced the fuser already...indicating a problem further down the line.

I really don't think its the fuser, per se. This user reports that it does successfully print some pages. Since the fuser is a mechanical object a fuser failure would be a consistant problem and never allow a page to go thru proper - unless it happens to be dropping voltage, resulting in less heat, meaning less fixing.

Traxus (i think thats spelled wrong), you can update the firmware from a PC MUCH easier....id borrow one and attempt it. All the info is there on the Xerox site, and the program is availible for download. I'd see how it behaves on a PC with some vanilla applications.-BUT- now you at least have a spare to steal parts from when your main PCB goes bad and exta rollers handy. Just keep family pets away from whereever youre gonna store it!!!

We could go on all day about this printer and without being there to observe and dig into it, and the related software, we might as well be throwing grass seed on the asphalt. Don't let experience and what you learned from certifications lock you in to one course of action, and treat the disease and not the symptom. My advice to techs is to learn every bit of software possible from drivers to photoshop or at least be gently familiar with it.

As far as constructive advice, I think we've all given enough.

Hello there,

this is in reference to theprinterfixer's post which I have quoted below. "If you look in the fuser door you will see a exit roller. It is in the door side not the fuser side and when you almost close the door you will see it lines up just above the fuser. It has about 4 black rollers on it that over time get really spongy. They can also get to the point where they break down and melt, that may be what you are seeing on your prints, melted rubber. If so you just need to order a exit roller assembly."

I need to purchase this assembly, or even just the spongy rollers as I believe I can remove the single gear and replace it successfully. Does anyone have a part number or idea where to get either the whole unit or the rubber rollers? On several sites there is mention of a "Xerox Phaser 7700 Transport Assembly, Inverter". Is this the technical name for the exit roller assembly?

Anyhow my printing is down until I replace these stupid spongy rollers.....Any help is appreciated. Thank you!

All the best,

Syn


Re: Xerox Phaser 7700 by Syn (edited 11/9/07 3:42 AM) reply + / -
Oh and thank you for your help so far, theprinterfixer. I have really benefited from your experience.

As I am an end user with 12+ years in large scale production printing using xerox products, I can say confidently that to minimize the types of errors you were all experiencing above, go with an approved paper. Nothing, I mean NOTHING is as annoying as running 20,000 copies on customer stock that is "quality paper" but keeps jamming. I believe that the issue with the clay might have to do with the static electricity transfer. At least with machines I am experienced with, the laser writes an image on the belt (photoreceptor or accumulator belt). The toner has an electric charge and magically sticks to the correct places on the accumulator belt. :D:D The paper is given an opposite electric charge, and as the paper passes close to the belt, the toner is attracted to the paper and sticks to it. Then it is fused. I am guessing that the certain paper types either have too much or too little stiction (technical term):P resulting in toner lifting, non fusing, or *ugh* sticking too well, and wrapping around the roller. It is possible that certain coatings or lack of coatings also cause the toners to react positively or negatively to them.

I have seen fewer problems with paper lately, but I think its because machines like the Docucolor 5000 etc. are just made for a wider variety of papers. The toner particles are smaller, and in my opinion that means that they will work with a wider variety of materials. No data, just my experience. Bottom line though - I won't run plain paper through it and if it is a 'metallic sheen' paper, I won't even try it. Only hammermill 28# or other xerox-y types go into the trays. Even colored paper - 24# or so - tends to curl excessively. Its a 'good paper' that is thick, but boy it is a pain in the tuckus.

As I used to graphic design exclusively on the mac, I can say that I have seen some weird errors relating to printing binary or ascii, and also with the language used to print to the printer. You can problem solve these things by varying your routine. Try saving as a .pdf, then printing from a mac and then a pc. Try changing the way that the machine is sending the data over.... you never know. In my job, I often have to try four or five different things to get a customer's file printed successfully.

So, I'm certain that regardless of what other problems are going on, the problems will be minimized if the correct paper types are used. And, try problem solving your workflow and see if you can pin down the problem with the graphics...

Anyhow, all the best guys and ty all around for the excellent posts.

The exit roller assembly used to be part # 116-1759-00 and used to cost $37 from Xerox. They changed the part # to 059K15613 and upped the price to $105. (bastards) about a year ago. I use at least one a week and feel bad having to charge customers that much for them but such is life. Hope this helps. Which area of the world are you in?


Re: Xerox Phaser 7700 by syn (11/9/07 3:33 PM) reply + / -
Thank you for the information. An additional question though: what phone number would I use to order this part, as I am just a consumer? I suppose it's on the Xerox website someplace but asking someone in the know often works better than searching.

Re: Xerox Phaser 7700 - Printing in only pastels by danaweb (2/6/08 12:07 PM) reply + / -
My Phaser is only printing in pastels since I changed the print cartridge 2 today. I have turned the thing off and then roller belt assembly is pretty hot, but I am not getting any erros or any strange printing other than the ink not saturating at all. Instead of printing CYAN it prints baby blue, instead of magenta it prints pink, etc. Does anyone have an idea about fixing this?

Remove the print cartridge, make sure the guide rail you slide the cartridge in is straight not bent, reinsert the print cartridge, make sure the other 3 are seated well, lock the handle down and see how the test prints are.


Re: Xerox Phaser 7700 by baddogs (3/13/08 4:00 PM) reply + / -
I am trying to trouble shoot a printing problem and hopefully someone can help me out! A blue smudge line appears down the length of the paper. The more I print, the worse it gets and then starts to appear on the left side of the paper too. If I limit my printing to no more than 3 pages at a time, there is no blue smudge line. I printed diagnostic pages and blue smudge lines appeared in the various color blocks. So then I ran the "Remove Smudge" cleaning and then the diagnostic pages looked fine (no blue smudge lines). I also replaced the fuser as required by the message on the front panel, but there was no difference in quality noted after the fuser was replaced. I thought this might be a print cartridge problem, but I am unsure since the Supplies Usage Report says the cyan print cartridge has 50% of its life left. I should also mention that I am using tabloid size 65lb cover out of Tray 1 (the MPT is misfeeding!). I set tray 1 to Thin Cover/Index paper. Any ideas?


Re: Xerox Phaser 7700 by Syn (3/25/08 10:41 PM) reply + / -
Another problem with my old 7700. the background has a light dusting of toner on the entire surface - If I have a wrinkled page the toner doesn't hit the wrinkled area so I know its not just me imagining the 'dusting.

It is a grey or black color, and is about 1% saturation - just enough to wonder what is going on. Print quality otherwise is pretty good. Is it the cleaning unit?

I want to use this machine for a large run of color but the client will bounce it I am sure; I have to get that dusting gone.

Thanks in advance for the help.

Re: Xerox Phaser 7700 by theprinterfixer (3/26/08 7:12 AM) reply + / -
First, determine if it's just 1 color. If it's the black switch the black imaging drum with the magenta, see if the problem follows the drum. If it's still the same check the waste toner cartridge. If it's really full the excess toner has nowhere to go and that may be what you're seeing, if so install a new waste cart. Lastly check the cleaning blade, if it's just been reset and never been replaced it may not be cleaning the accumulator belt correctly.

Hi there!
I am trying to trouble shoot a problem with a Xerox Phaser 7700 and need some help. Basically the printer starts up and upon printing, it jams halfway the fuser. Almost right before it comes out the tray.

I replaced the fuser, same problem. Also along the way I noticed the exit roller assembly was melted and replaced that already. But now I am stuck, can't figure out if it is a sensor or some kind of fuse.

I went into the service diagnostics mode and checked some settings in there based on the service manual and everything looks okay. Anyone got any ideas?

Thanks in advance!

You may have to reset the tech rep fault. To get into service diags turn on the printer while holding down the left and right buttons (back & Info). Highlight NVRAM Access and press OK.
Highlight Clear Tech Rep Faults and press OK.
Highlight each of the tech rep faults to clear, hiy ok, do this for all the tech rep faults. then hit the back arrow and scroll to exit diags, hope this helps.

i had the same problem. it was a magnet that secures the back door had slipped out of place thus the rear door was slightly skewed causing the paper rollers on the door not to feed completely flat.
once this was corrected the issue went away.

Hey Guys,

Thanks for trying to help out...I couldn't quite figure out what magnets you were referring to...but I found the problem...it seems the fuser exit sensor on the left door (fuser door) was broken....I didn't even notice it at first...but finally found that as the problem...part # was (116-1543-00) Let me know if any of you have it to sell and I will buy it by Monday...Thanks!

We are having issues with our phaser 7700gx. I have followed all of the remedies in this thread to no avail.
We have been getting the laser error 10 intermittently for some time time now. Usually powering off for a while solved the problem. We have also been getting the replace accumulator belt warning for awhile.
Today it quit during a run of about 300. It will not start again. I replaced the accumulator belt but it did not resolve the issue.
When we turn it on we get the Textronic screen, then the warming up screen with the flashing green light, then a click all goes dark and it starts this cycle over again.
does anyone have any ideas?

Thanks


Re: Xerox Phaser 7700 by Anonymous (5/13/08 6:32 PM) reply + / -
Error 10 is the laser and FYI this model will NOT be supported after the end of the year...IMHO spending 2k to replace the laser
is a questionnable investment.

If it's not the laser causing the reboot then it's probably the hard drive going bad. I have replaced many for this...

Just wondering after all the comments about paper: what is true laser paper to use with these machines? I always use Xerox Colotech+ and Premier, which should be good for this printer, but since they also have a star rating for inkjet, I suppose they are multi-purpose?


Re: Xerox Phaser 7700 by Megacom (5/23/08 5:07 AM) reply + / -
I think this whole paper thing is a myth that needs to be busted! We have had a 7700 running for 5 and half years and printing on Art Paper/board (clay coated), Normal Office Bond paper, Ivory Board, Vellum and some embossed boards with no problem related to paper or imaging. Our customers are quite particular about the quality of work (especially for proofs) so the imaging problems above can't be paper related.

I kind of get that feeling as well. But overall, this is the third 7700 so far that has really severe problems with a good output, so I'm wondering what makes these printers so sensitive. Are the drums very sensitive to aging?

OK, The "Printer Fixer " guy is technically correct on the paper thing
Just because something has worked in the past and you were lucky does not mean that the luck will continue forever.I have seen people get a bad batch of paper that caused problems and their answer was ..well it is the same paper we always used..
but when they changed it..the problem went away. That is like driving down the road without a seat belt and saying..well i never needed to use it before...or .. my printer always worked great til today..
yea it is broke..it is not working..just cuz it always did before does not mean things do not change
Little changes can make a big difference..just cuz we do not see a difference does not mean there is not one.I have seen counterfeit cartridges from china cause problems..you name it it happens.I am not sure why you guys were so hard on him..try it then say yes it fixed the problem..or no i did not and go from there

Susan, remove tray 1 and check if there is a sheet of paper that got jammed behind tray 1. A false missing tray maybe caused by a faulty tray size sensor. The jam at fuser just means the printer was expecting a paper that never got there...

In the printer's "Information Page", under "Fuser Information" I am told that the 50pv fuse is "Blown" and the 90 day fuse is also "Blown".

What/ where are these and with what fuses should I replace them with?

Thanks!


Re: Xerox Phaser 7700 by Anonymous (7/17/08 6:37 PM) reply + / -
First you don't need to replace the fuses...These are just used and indication that the fuser is no longer new and it's out of warranty .

For the color cast it's probably caused by a imbalance in the colors, so you should perform the color balance procedure under the "Troubleshooting/Print Quality Problem/Balance Colors" menu...

I just changed two of the print cartridges that were at 4% and 8% full. This didn't do me any good either. Maybe it's the fuser assembly.

I replaced the cyan, magenta and yellow print cartridges (18%, 8% and 4% full) and the color cast all went away! But I still have a continuous repeating black "pattern" on the page, abut 1/4" wide, like there is a problem with some roller (but which one?).

The repeating pattern happens every 2 1/8" approximately. There is a lighter black "line" too, but on the other side of the paper.

I've asked the printer using the menu to REMOVE PRINT SMEARS several times and it doesn't work.

Any ideas? Which roller repeats every 2.125 inches?

At post I got "Error 30 - Accumulator Belt Home position took too long" I had replaced the Accumulator Belt, as suggested by Megacom, but no dice.

Solution:
"You may have to reset the tech rep fault. To get into service diags turn on the printer while holding down the left and right buttons (back & Info). Highlight NVRAM Access and press OK.
Highlight Clear Tech Rep Faults and press OK.
Highlight each of the tech rep faults to clear, hiy ok, do this for all the tech rep faults. then hit the back arrow and scroll to exit diags"

Hey Subs,
It sounds like you have a damaged print cartridge for the color black. Try swopping the black print cartridge with the yellow and see if the mark changes to yellow. Unless you the mark is big or you are doing some critical work you could probably survive for a week or two till you get a replacement.
Hope this helps.

The Company I support has a Xerox-Tektronix Phaser 7700 color printer and the users complain that the colors on the print outs do not match the colors on the monitor screen. For example, the blue in a slide on monitor screen is a darker blue than what gets printed. I don't know much about these printers, but I have gone through the menus and made adjustments that made some improvements to the colors, but still not an exact match. Does anyone have any suggestions for me on what to try next.


Re: Xerox Phaser 7700 by subs (7/24/08 3:39 PM) reply + / -
Megacom, thanks for your suggestion. I actually replaced all three of the color cartridges and the "haze" all went away. The only thing that remained is a thick black gooey line down the middle. Further research showed that the line came from a MELTED rubber roller that is one of four on the metal rod in cover on the left. The roller is next to the fuser when closed. For some reason the fuser must have overheated, causing the roller to become goo.

Since I don't know where to get parts numbers for this item, I decided for now to cut the roller off the square metal rod. This I did, and the black line went away. I only hope that the absense of this little rubber thing (for now) will not cause paper jams in the short term. Maybe we'll be OK for a while.

The rubber rollers that tend to melt can be safely cut off - they are side exit rollers, which were meant to deliver paper to an optional accessory which xerox never actually released.

Blue band across top of page by snriac1 (11/1/08 12:34 PM) reply + / -
I every time I print a page that has any color, I get a blue band across the top of the page. I have switched the color cartridges around and that didn't fix the issue. When I pulled out the blue color cartridge, it appears that the fuzzy roller that the toner comes out of has some defects. None of the other rollers have this. I'm not even sure what this part is called.

Answer for Snriac1: It appears to me, that your Cyan Developer Cartridge looks damaged, part number 116-1114-00. It consists of a mag roller, i do not think it is fixable. I'm not 100% positive, it's been about a year since i worked on a Phaser 7700, so a 2nd opinion would not hurt. Good luck.


Re: Blue band across top of page by detonation (11/5/08 11:18 PM) reply + / -
That's indeed a damaged developer, might be costly :(

By the way, the developers running out of carrier beads is a common problem with the 7700 and might be the cause of many of the problems with blotched prints. In that case, just the beads can be replaced.

I have a 7700 that has been a workhorse since 2003. I needed to upgrade the firmware and followed the instruction on the Xerox Website. However, the ftp site to my printer required a login and password. I have never set one. On the configuration page it lists them as "not set." However, the login screen will not let me pass with the entry form left blank. Unfortuately, it did not tell me I need a username and password until it started the upgrade. Now my printer is stuck on "Do not turn off..." What can I do?

I am getting the dreaded Error 10, the printer cycles through all four print cartridges being missing, and then repeats the error display.

If I go into the Service Diagnostics menu, I see the only fault is <6,382> SOS Length C Fail

I have checked all of the doors, including the ones under the MPT tray, and when opening each one I get a "door open" error for each door, and when closing the doors, the door errors go away. Don't think it's the door sensors at this point as others with the error have suggested.

The printer was fine on Friday when I left, and was sitting on "Error 10" this morning when I came in. The printer hasn't been moved since Friday.

Any ideas on next things to check?

I had another 7700 do this in the past, never could fix it, ended up parting it out and throwing the chassis away. Bought this one as a replacement, and have several thousand pages printed so far error-free and beautiful.

Re: Xerox Phaser 7700 by nivek (1/7/09 11:36 AM) reply + / -
still sounds like a blade is failing. look and see if something has gotten stuck inbetween the two. but most likely your problem is in the drum unit. Blades age or get preworn and can wear out before the machine thinks its time to replace. the machine goes by number of pages it doesnt check each individual part on the drum and base it on that.


Re: Xerox Phaser 7700 FUSER RESET - HOW TO by stalkerzonedog (1/19/09 10:25 PM) reply + / -
I was really annoyed when I found out that Xerox programs the 7700 in the following way:

removing and replacing a NEW Fuser unit several times (2 or 3), or swapping from one printer to another, leaves

it with only 10% functionality. in times when we should not waste resources, and as these printers are trickling out

of the hands of large, wealthy corporations and into entrepreneurial small businesses without spare cash, a safe

work-around is essential. this will not revive a fuser which no longer heats or is totally worn out. this will however,

reverse that feeling that you have been cheated if your fuser is good despite the life counter.

here we go:
0. get quantity 3 of 30 milliAmp micro fuses to match the ones inside your fuser endcap (see no.2). available

online or call your local micro-electronics repair or supply house (sorry, country bumpkins)

http://www.sourceresearch.com search for type 279.031

1.(find an electronics repair shop well equipped with a soldering iron and a phillips head screw driver)

2. ask them to remove the two small screws on the fuser endcap where the wiring harness connector is. they will

see 3 small fuses on a loose, miniature circuit board. Two or three of these should have no continuity for this fix to

work.

3. have them replace the 3 fuses. takes 2 minutes. they are 1/32 watt, also called 30 milliAmp. if you want to find

your own fuses, i found some made by LITTELFUSE, they are about $5 each. clearance is an issue, the

LITTELFUSE fuses are 1/8" taller than the originals, so the cicuit board needs to be nested with the wires in order

to replace the cap. or find fuses that aren't so tall. in any case, be sure to have them reattach the black plastic

circuit-board holder which protects the circuits from shorting out. the new fuses have intact filaments which

cannot be seen with the naked eye, but can be tested with a voltmeter seeking continuity, or 0 ohms.

4. have them replace the cap carefully without pinching wires and re-install the fuser.

5. print Supplies Usage Page to confirm your fuser is at 100%

6. remind the repairperson to unplug his/her soldering iron when finished.

Re: Re: Xerox Phaser 7700 by printergodless (2/4/09 10:24 AM) reply + / -
The Xerox tech has no motivation to replace fuses that are not even part numbered and has no proceedure to follow. The situation of getting a new fuser to indicate a % use not equal to the actual is due to swapping fusers and exposing the nvram data to a unexpected situation.
The best way to avoid this is to swap fuser ends when experimenting with fuser/PQ issues so you keep the fuser count consistent.

Well I've had (more than once) the wiper blade of one of the drum cartridges go bad, leaving some toner on the cartridge all the time. If you print a white page and the yellow band is still there, there's a good chance the yellow drum is bad. Visually inspect the drum and see if there's any toner build-up on one of them (the yellow one being the most likely candidate). If there is, replace the cartridge.


Re: Xerox Phaser 7700 by printergodless (3/10/09 8:22 AM) reply + / -
Swap the print cartridge to determine if it is a print cartridge issue, if the problem follows the cartridge then replace it.
If the problem remains with yellow then we a developer issue, replace the developer housing and developer beads or remove the developer housing, vacuum out the old developer and replace it with new material.

From what I've read about this error (I've had it as well), typically this is related to one of the doors (often, the small door under the MPT) not closing fully. Make sure all doors are closed properly and no sensors are broken. Another option is one of the connectors from the laser units to the print engine control board not being seated properly.

In my case the Laser Unit was actually bad and had to be replaced. It takes some time (and the service manual) to replace it, but it can be done. Apparently one should also recalibrate the laser unit when it is replaced although in my case, it was printing perfectly without calibration.

If your problem turns out to be the laser unit and you have trouble finding one, I have one I could sell.


Re: Xerox Phaser 7700 by kfrost (3/11/09 12:18 PM) reply + / -

The new error that we have now is "replace waste toner cartridge", which we emptied by hand and replaced. It still says that the cartridge needs to be replaced. Is there anyway to bypass this error and still have the printer work? Is there a chip or something we have to disable in order to re-use the old waste toner cartridge?

Hi all, I just bought a Phaser 7700DX on fleabay for 0.01. Thanks to this list of answers I then fixed it for another 0.01! The listed fault was missing toners etc after a move. After slamming the front door and paper trays those faults cleared but it then reported 'jam at fuser' any time I tried to print. The problem was the little black plastic sensor swing arm inside the fusor left hand door just below the famous melting rollers. The last 1/2" had broken off. I drilled a 0.8mm hole into the remaining plastic then heated a half pin red hot with a lighter and melted it into the hole. I then bent the pin to emulate the rough curve i thought the original had described; instant success!
Thanks for all the info and I hope my story helps someone in turn.

Do any of you clever people know if the Xerox transparency paper 016-1897-00 work in a Phaser 7700? The only info I can find is that it works in 'Phaser 7300, Phaser 1235, Phaser 2135, 6100/6120/7400 and Others as listed by Xerox' ('Others' that I cant seem to find...)
I can get this stuff fairly cheaply but the stuff explicitly for the 7700 ie 016-1951-00 is very pricey and only available in bulk.
The other stuff, 016-1897-00, IS definitely Xerox colour laser transparency film: I just don't want to find out its meant for a newer printer with, for example, a lower fuser temp. I dread trying this stuff to then find its melted all over the paper transport path!

Re: Re: Xerox Phaser 7700 by Ed Gray (5/2/09 3:53 AM) reply + / -
After emptying the waste cartridge by hand use compressed air to clean up. You can usually get the window to clear with a bit of perseverance.

A compressor is essential if you want to keeps parts running beyond their normal life. Stripping down and blowing out all remaining toner seems to work wonders.

If you're getting colour smears then sometimes the roller and waste transport on the imaging drum can be cleaned up but it can also be cased by the accumulator belt cleaner not clearing the toner. Many of these problems seem to be caused by the waste toner not getting to the waste cartridge efficiently. Take the printer outside and clean all the pathways with compressor.


Re: Xerox Phaser 7700 by printergodless (5/17/09 7:37 AM) reply + / -
Regarding the cleaning of waste cartridges for reuse, although it works OK as far as the printer is concerned, it is not a practice I would recommend.

Toner dust is not good for your health and using compressed air will cause you to inhale the toner particles. I recommend you use a toner vacuum and brush to clean your printer.

Hi,

Having some more trouble with my 7700. When printing double sided on 32# laser paper, the paper ends up creasing on the trailing edge.

If I print single sided, I don't see the wrinkle. It is very slight but appears to be fused as it look like it's been pressed...

I do see very occasionally a wrinkle on the trailing edge of 11x17 single sided printouts.

My assumption is that something is out of alignment and that is why it is creasing.

I have books due this month and was going to use the machine for them. Since they are double sided I could use some help troubleshooting the problem.

Thanks, and have a great night!

Syn

I bought a used 7700 years ago. I was looking to upgrade the firmware but it asking for a password and user id. to install it. Any idea where to find or reset this?


Re: Xerox Phaser 7700 by upham (6/7/09 4:58 PM) reply + / -
I have been getting an error message, "TRANSPARENCIES IN TRAY 1: PAPER EXPECTED." Someone had posted a similar message to this thread.

I bought my 7700 used and this "TRANSPARENCIES" error message has been occurring pretty much from the get-go. This error occurs regardless of paper #, size of paper (letter or tabloid), and which tray I am printing from (either MPT or trays 1-4).

The only way to fix the error is to pull out the tray and push it back in sometimes that fixes the problem for a while, other times the printer outputs 1 sheet of paper and then the error message is back. Very frustrating and time-consuming.

We've the exact same problem
the Polygon Motor Failure error was coming up intermittently
and would go away after restart
The replaced a Printer Cartridge and soon after the Polygon Motor Unit error 11
was pemenant and also going throught print cartidges say one after the other is empty
tried everything we know how in Diagnostics mode - deleting tech blah blah
but nothing works
I'd believer the motor might be kaput if it weren't for the printer cartidges error in tandem

have you had any luck?

Great printer but Xerox wants them out of service. The drums are too much. Also don't try to buy them from A Matter of Fax, they will send you generic toner and argue that they are imaging units.

Double check the doors, especially the one on the bottom left. Press the door and hold it to see if the error disappears.

I still sell 7700's at a regular basis, they are good cheap machines and have have loads of consumables for them. The print cartridges are, except for the drums, identical to the DocuColor 3535, and those can be found very cheap. Just swap the chips for resetted 7700 chips and you're good to go.

We're still seeing the same error 9-911 while holding the doors in. I looked for bent pins or clips on both left doors (upper/lower) but didn't see anything like that, not sure what im looking for. I also pulled the fuser and re-seated it to make sure nothing was jammed up behind it.
When i moved the print cartridge to another slot, that error says to replace it. So obviously the new cartridge went bad (how??).

Does the 9-910 or 9-911 error mean anything other than a door issue?

Poul, I mean that the DocuColor 3535 drums (or Workcentre C3545 drums, and I guess a large number of other drums) are identical to the 7700 drums, except for the chips, which are different. The chips can easily be swapped, and 7700 drum chips can be resetted or bough separately on eBay. For the USA I'm not sure where to get your drums, but here in europe the DC 3535 was very popular as a lease machine and supplies are available in vast quantities. I buy drums at $70 max and a lot cheaper if I am lucky. 7700 drums I can get for that price as well, but they are just much harder to find. The part number is correct btw.

Do any of the larger xerox production machines, for which the toner seems to be much cheaper, use the same toner as the Phaser 7700? It seems by using the less expensive DC 3535 drums, one of the big cost gotchas can be solved. Now how about a work around for the ridiculously expensive phaser 7700 toner?

Re: Re: Re: Xerox Phaser 7700 by detonation (10/3/09 6:49 AM) reply + / -
David, the developer is a charged roller and the developer beads are charged particles to which the toner 'sticks'. These developers transfer the toner onto the drum cartridge, and it only 'sticks' to the drum on those places where the laser unit did (or did not, I always forget) 'wrote' on the drum.


Re: Re: Xerox Phaser 7700 by detonation (10/3/09 6:52 AM) reply + / -
James, I'm not too sure about the 7700 toners, but the toners for the 3535, M24 and 7750 are all the same (the cartridges won't fit unless you modify them, but the toner used is the same). The 7700 can be had pretty cheap by the way, I sell them for less than the 3535 and 7750 toners.

My Xerox 7700 was working fine until I replaced the transfer roller, fuser, accumulator belt and belt cleaner assembly which were all low on remaining use. With $800 of new parts in it, the paper started jamming in the fuser. I put the old fuser back in and same thing happened. With heavier toner coverage the paper actually wraps around the fuser and with lighter coverage jams half way through the fuser. This 7700 never had fuser jams before on any type of paper coated or uncoated. (I do use all digital certified papers - Mohawk, Sterling Digital, Hammermill Color Copy). I replaced the exit roller assembly and the same problem occurs. The service manual refers to replacing the image processing board P/N 671-5268-02 as the final solution to all exit and fuser jams. Is this the next logical thing to try?
I did get a generic yellow toner (first non-Xerox I have tried and it was by mistake). Could this be the problem and with the new OEM yellow in it, is there a way to flush out the old generic yellow? I tried printing solid yellow pages but of course they wrap around the fuser. Any ideas?


Re: Xerox Phaser 7700 by detonation (10/23/09 1:41 AM) reply + / -
Well, to see if it's the yellow toner you should print some blank pages probably, and see if it also jams then.

I had the same issue when we replaced our fuser unit. Turns out, we over tightened the two black knob/screws at the top that secure the unit. I didn't crank down on them, just a snug fit which was apparently too much. When i loosened them a touch, paper stopped jamming right away.

Hope this helps.

Re: Xerox Phaser 7700 Paper Jam Fixed by HeartPrinting (10/26/09 9:11 PM) reply + / -
Well I actually solved the paper jam problem. I tried loosening the 2 spring tensions screws on the fuser but that didn't help. Then I printed solid boxes in cyan, magenta, black and yellow and only the yellow one stuck in the fuser. Turns out the yellow generic toner I used was near the end of the tube and apparently it's fuser temperature was lower than normal. So anything with moderate to heavy yellow toner was jamming. I ran solid yellow at 10%-50% screen and it went through okay. Once I changed it to 60% or more yellow, it melted to itself in the fuser. With new Xerox OEM yellow toner in the printer, I cleaned out all the old yellow by running about 100 sheets at 50% through. Now it's working fine. No more generic color toner for me. Thanks all for your ideas!

Tom, you can use 116-1759-00 which is the export assembly for the Phaser 7750. Afaik the exit rollers are really needed. Alternatively, you can use the rollers from the 7760, Docucolor 3535 and pretty much all WorkCentres that have the same form factor (2128/2635/3545, 7228/7235/7245, 7328/7335/7345).

Phaser 7700 Questions by ayarusso (3/21/10 11:07 AM) reply + / -
I replaced the MPT assembly on my 7700 a few days ago because it would not pull sheets in about 25% of the time. Very annoying, but seems to be fine now. However, today I went to print some sheets from the standard tray and the pages kept jamming before they even got into the fuser.

After banging my head a bit, I found this page where people mentioned the magnets for the door under the fuser door could become misaligned. Sure enough, one of the magnets had actually popped out entirely from the door and was firmly attached to the printer itself. I snapped the magnet back into place and all is good again. So many thanks to those who brought this up. :)

Four questions while I'm here:

1) What 7700 consumables work on the 7750?

2) Are there any significant improvements between the 7700, 7750, and 7760?

3) I had outstanding print quality when I first got my 7700. The printer has less than 100K prints on it, but over the years the print quality has deteriorated. I've replaced all the consumables, and even recently installed a new Accumulator Belt. The new Accumulator Belt actually did help a bit, but the print quality is still not 100%. With some colors I can see faint banding, and it seems the toner coverage isn't as "solid" as it used to be. Can this be a developer issue? That's really the only thing I haven't swapped out on this printer.

4) Prints from my 7700 are generally darker than they should be. Are there any reasonable solutions to this? I print from a wide variety of apps and this dark output is fairly consistent. I am using OS X.

Thanks in advance for any insight!



Re: Xerox Phaser 7700 by detonation (3/25/10 9:35 AM) reply + / -
1) Only the belt cleaner, wate container and transfer roller are compatible. The accumulator belt is as well, but I think you will need to change the chip on it.

2) Yes. 7750 offers better quality, better speed, and solves all of the issues mentioned in this thread.

3) Developers, no doubt.

4) Haven't been able to solve this either :(


Re: Xerox Phaser 7700 by ayarusso (3/25/10 9:41 AM) reply + / -
Thanks for your answers Detonation. Figures only the inexpensive parts would be the same (like the Waste Toner cart). Is the toner actually different in the 7750/7760, aside from physically different canisters? Interesting about the accumulator belt, since that's the most expensive consumable.

Regarding the developers, do you know of a good source for them? I replaced one developer some time ago and it was a rather involved disassembly/reassembly job. If I do it again, I'd want to replace all four at once.

Thanks,

Re: Phaser 7700 Questions by shugnite (6/30/10 9:54 AM) reply + / -
1. Toners (empty from 7750 or 7760), fusers (just changing a gear will work), drums (change the chip), accumulator belt (but not the cleaner).

2. Not really, but 7760 has better drum units, more options for paper selection and better memory. The toner, fuser, belt, developer is the same for 7700, 7750, 7760, 7228, m24, 3535, 2240 etc. what xerox have done is just changing the shape of the toner cartridge and added chips here and there but everything is the SAME!!!

3. The 'developer' is your problem because its content is depreciating especially if you are using non xerox toner. The more the developer the more solid your colors are.

4. Prints will be darker because the developer is low. just look for a spares machine remove the developer and add to your developer housing and it should print normally.

Hi all. I am having a problem with my phaser 7700. When I print more than 3 pages or so of the same page, I start to get a sheen of toner over the entire page. First yellow, then magenta and then cyan, covering the entire page. This happens even if I am just printing a black document. It is cyan on the left of the page for about 1", then magenta for about 7" and yellow for about 2" (sometimes the sizes change, but always in that order). I have tried changing the imaging units around, but that doesn't seem to make a difference. It gets progressively worse the more copies of the page it prints, but if I print 1, then another, then another etc it doesn't happen nearly as fast or as bad. Any ideas?

Re: Re: Xerox Phaser 7700 by mw11566 (7/26/10 2:00 PM) reply + / -
Accumulator has 60% left, and I installed a new belt cleaner assembly about 6 months ago, and has 85% left.

When did the problem start?


Re: Re: Xerox Phaser 7700 by MichaelW111 (7/27/10 9:02 PM) reply + / -
It started about 2 months ago, and has been getting progressively worse. It started as just a yellow cast over the whole page, now it is all the colors, and even when just printing black.


Re: Xerox Phaser 7700 printing too dark by Heart Printing (7/27/10 10:43 PM) reply + / -
An easy fix for the 7700 printing too dark is to get a copy of the PhaserMatch color calibration software. Once I ran the program and built a custom color profile, I was able to calibrate to match what I needed. Basically you redefine the mix of CMYK being used. I am a color specialist and have had training from EFI (Fiery products)and Konica Minolta so if you need help, feel free to contact me. It's worth buying the software if you need to match color consistently. I recalibrate every time I change a consumable... but I own a printing company and consistency is key.

Hi we had error messages on a constant rotation, following the advice on here we pushed the friction clasp down on drawer B and shut it. This solved the problem, unfortunately we are now getting constant paper jams around drawer B. We were not rough with it, and did not bend the plastic etc. Any one got any ideas


Re: Xerox Phaser 7700 by cdp (8/6/10 6:43 AM) reply + / -
Michael, regarding color on page...I looked through my records and I had a yellow streak along the right edge top to bottom about an inch wide. I had this same proble twice in two years. Xerox replaced the transfer roller which had 46% life left and they also changed the developer unit.


Re: Xerox Phaser 7700 by WHITMAN RINALDO (8/6/10 3:48 PM) reply + / -
Only the developer would cause background issues on the page. See if the image goes all the way to the edge of the paper.

7700 developer housings are PN 116-1115-00, and you will need to buy the powder also.

Thanks,

Door B has got 2 magnetic latches. What happens a lot of times is one of the latches comes off and is stuck on the frame instead of on the door. If that's the case just snap it back into the door.

The rubber rollers that tend to melt can be safely cut off - they are side exit rollers, which were meant to deliver paper to an optional accessory which xerox never actually released.

THX Huckle for the thread. I did this (cut out 1 melted middle roller off of the rod)and i am printing with no problems (yet). I may consider replacing the exit roller part but if all it is doing is utilizing its gear mechanism for the adjoining paper discharge rollers then who needs new exit ROLLERS on the doorside.
Before cutting away the melted roller I first removed the rod entirely and noticed that the paper had advanced far enough up to theoretically slip into the paper discharge rollers (which of course were not functioning without the support of the exit roller GEARS. Again I repeat this is just a THEORY. I still have use of 3 out of 4 of the rubber exit rollers doing or not doing their part to push paper out. Anyway for now thats $105 bucks saved.

We had the same problem, and I took of the rubber rollers. It worked well for a few month, then I got an invitation Xerox presentation. While looking at the new machines, I asked a clerk if those rollers were still available, and yes they were. So I ordered the set, just to have the machine in an original shape. Works well so far.

Re: Xerox Phaser 7700 by beefog (10/5/10 9:23 AM) reply + / -
I am having a weird problem. The printer prints perfectly, however when the paper ejects into the tray, it doesn't travel all the way out. The printer doesn't jam, but additional pages force the previous ones to fall on the floor. If printing a large PDF for example, you find all of your pages on a pile scattered on the floor. Not sure why, but the pages seem to be about 2 inches short of coming all the way out.

Anyone have any ideas?

I've got a 7700DN that hasn't been used very much for a couple years. I've recently begun checking it out in order to get it back up and running and have found echoing, residue (a dirty looking overall appearance), and dirty "streaking" (but really it just looks much like the overall residue) in the direction of the paper travel.

I've measured the repeating defects and think I've determined that the print cartridges are probably the source of the problem (specifically the cleaning blades). Someone please correct me if this doesn't sound like a good diagnosis.

The machine hasn't been used much (17,000 pages) and I'm not sure it's going to get a ton of usage going forward, however, I'd like to have a working printer without spending a ton of money.

To that end, how difficult is it to swap out cleaning blades on the print cartridges? I've found someone that sells them and I'd like to do that first as an inexpensive test to see if I've located the source of the issues.

I'm pretty handy and patient, and don't mind getting dirty. Can someone give me a sense for how difficult and what I should watch out for? Would be much appreciated.

Thanks.

XEROX PHASER 7760GX
Transparencies come out with gaps white lines where image should be.Thes files are just large vector type.
I have no problems printing solids to paper or the exact same file to white paper.
All trubleshooting shows no print problems,(to paper).
These gaps seem to line up with the transfer roller.
The transfer roller indicates 25% life left

The message "Warming Up" at start-up is stuck on our Xerox 7750 Phaser. We've had that printer for a long time and I've never seen this. I am not finding anything when I go the the printer's IP address about any errors.
The printer is networked and our IT person thinks it may be related to the fact that someone in the office tried to hook up to the printer from their Mac Laptop. We are all in a PC environment.


Re: Xerox Phaser 7700 by dmzcompute (7/8/11 2:58 PM) reply + / -
Tell you what turn the printer off and then disconnect the network cable. Now turn the printer on and see if it comes to ready. If it does plug in the network cable and see what happens. If it does not get to ready and keeps the same message as above I would hazard a guess that the fuser needs to be replaced.


Re: Xerox Phaser 7700 by clipper24 (edited 7/13/11 12:44 PM) reply + / -
I had already tired turning it off with the network cable out but the same thing happens. Xerox tech support was no help (I coudn't understand what the girl was saying) I changed out the fuser but that did not work. Any other suggestions?

There is still loads of Toner in the Cart. Ive shaken and moved the Toner around inside. Ive turned it on and off repeatedly with no result. I refill my own carts so I know there must just be a sensor inside as a posed to guess work. Help please !

A great solution to do it yourself on resetting the crum drum chips for the 7700 printers is to buy an infinite re-setter. Pays itself very quick versus buying individual crums everytime you need one. Just connect it to the resetter, flip the switch, wait until a light comes on, then reuse the crum in your printer. Very cheap at $75.00 free shipping.

The same company also makes infinite reset chips for various Xerox Toner printers.


Re: Xerox Phaser 7700 Fuser jams by jsorealty (1/5/12 5:16 AM) reply + / -
I have a Phaser 7700 that just developed a strange problem of paper jamming in the fuser. It is only jams on pages that have sold fills of toner on the leading edge of the paper that jam. The solid fill test pages always jam. It is independent of paper size. If I print the color test pages the first four pages with the basic colors prints fine, then the 5th page (a solid fill of orange-red) always jams.

It is not the fuser, as I have three of them and they all do the same thing. I am using non-OEM toner, but I have been using it for years with no problem. I am using the same paper I have used for years.

Any ideas?

Hi there again,

our printer had been sitting around for 11/2 years without printing. Now we would like to refresh it, so we printed a few test sites. The result is awful, all prints came out in a blurry way, like someone has used water color to cover the whole page, except the edges are printed well. Magenta looks like pink, yellow like orange, the testmenupages are orange on the left 1/3 of the paper, the other 2/3 are magenta pink style with a slight gray bar on the right side. All pages are in upright format.

Please indicate how I should start to get printer back to print well.

Best regards,

Tom

Not exactly Houston but I am in Baytown.

I wouldn't necessarily describe my printer as a parts printer but I might be persuaded to sell it. It needs a black developer (already changed the yellow) but other than that it works just fine. I also have a bunch of spare parts for it.

I bought it for my wife's business but she never uses it and doesn't like how big it is.

If you are interested shoot me an email al_carl_88 (at) yahoo (dot) com.

Hi all, I have a Xerox Phaser 7700 and it's jamming at the fuser with every print out. I called a repair guy to take a look and it didn't jam not one time. A few days later I needed to print 300 copies on laser paper and it printed about 30 and then started jamming at the fuser every time. Everything jams now....startup page, configuration page, etc. Fuser has a lot of life left according to the consumables page. What is the fix here? Thanks for the help!
