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
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?

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 Gary
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.
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...
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.
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!
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.
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!
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.
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!
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.
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.
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!

Re: Xerox Phaser 7700 by Tanxrus (11/7/07 9:02 AM) reply
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!
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.
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.

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!

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

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.
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?
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.
to savvyspe.... i had same issue. check magnets on rear door to be sure one hasnt slipped or broken off. with mine the rollers on the door were not alightned due to the door being ever so slightly skewed. once this was taken care of the issue went away.

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?

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

Re: Xerox Phaser 7700 by Anonymous (6/27/08 6:29 PM) reply
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...
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...
Anonymous - thanks. Unfortunately my 7700GX model does not have the "BALANCE COLORS" menu you mention. I have tried all the other Troubleshooting options available to me. 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?
Thanks!

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.

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.

Does anybody know if there is a way to bypass the "replace 'color' toner cartridge" error and just go to black and white printing? I don't have a yellow toner cartridge on hand and it will take a couple of days to get one. I would just like to print in black and white until it arrives. Thanks, BobR
This is a great thread. It covers 2 of the 3 problems I am having. I have already replaced the exit roller that melted and the magnet that was broken (and staying inside the printer, not on the door).
I also have faded/blotchy print on the sides of the cyan color (outer 1-2 inches, both sides). I have already swapped the OPC's (print cartridges) and used the laser cleaning wand.
