 | HP Laserjet 5 paper jam by Finkle1 (12/17/02 12:30 PM) reply | + / - | There is no error code displayed except " remove paper jam ". The first sheet of paper will be half out of the fuser and up the exit assembly, the second sheet will be under the toner cartridge and the third sheet of paper will be half in the feed tray. Rarely the printer will feed the first page through and then jam there after. There is very slight yellowing burn from the fuzer on the first sheet. Exit assembly??

 | Re: HP Laserjet 5 paper jam by gentleman (12/17/02 12:50 PM) reply | + / - | Pull out the fuser and carefully check the gears for missing teeth. I had an HP 4 that jammed intermittantly and drove me crazy until I replaced the fuser. No more jamming.

| Re: HP Laserjet 5 paper jam by LPB (12/17/02 6:07 PM) reply | + / - | Try replacing the exit rollers. If that doesn't do it your looking at a PIU.
|
 | Re: HP Laserjet 5 paper jam by finkle1 (12/18/02 7:34 AM) reply | + / - | PIU?
|
 | Re: HP Laserjet 5 paper jam by moe  (12/18/02 9:03 AM) reply | + / - | The PIU is the entire paper feed unit. You have to remove the covers to get it out. Try feeding from the MF tray. When the PIU goes bad, it will still feed OK from the MF tray.
|
| Re: HP Laserjet 5 paper jam by Finkle1 (12/18/02 10:32 AM) reply | + / - | OK! It does print fine from the MF tray. What does replacing the PIU entail? If it can be replaced i do have a spare 4+, are the parts compatible? Could i purchase these parts from you Moe? I appreciate the advice as i need to get this printer up as ASAP!
|
| Re: HP Laserjet 5 paper jam by moe (12/18/02 11:08 AM) reply | + / - | The 5 and the 4+ use the same PIU. Like I said, you have to take the rt. cover, the top and the left cover off. You also have to take the rt. front corner off. If you'd like visual aid, our 41.3 error kit shows the whole procedure of removal and replacement of the PIU.
|
| Re: HP Laserjet 5 paper jam by Finkle1 (12/18/02 1:59 PM) reply | + / - | Do i need to purchase the 41.3 error kit in order to view the placement of the PIU? Could or would you be willing to email me a still frame from the video or just the video. Once i can identify the part i can do the repair no problem so i just need a pic of what im looking for.
Thanx for all the help everyone!

| Re: HP Laserjet 5 paper jam by moe (12/19/02 5:43 PM) reply | + / - | We've fixed a couple by replacing the PIU. We tried replacing, lubing, cleaning everything on the PIU without any luck. The replacement PIU fixed it. If you try the MF tray, you'll probably find that works ok. We just spent hours on one that did the same thing and replaced just about everything without any luck. Turned out that it was the optional 500 sheet feeder causing the problem. Exactly the same as you describe, but sometimes it would feed 200 sheets ok, other times only 5 before it jammed. I can't explain that one either. We proved it by sticking another printer on the tray and the problem occured on it as well.
|
| Re: HP Laserjet 5 paper jam by Finkle1 (12/20/02 12:44 PM) reply | + / - | Sounds exactally the same! I went through and checked al the rollers and cleaned them. It printed fine for the end of the day. Today first print job ERROR.

| Re: HP Laserjet 5 paper jam by dmzcompute (1/12/06 4:24 PM) reply | + / - | That is because the back door had to be removed to install the duplex unit in the first place. You have to put the back door on after removing the duplex unit or you will get an immediate paper jam message on power on. Most time people can not find the old back door and have to get another one.

| Re: HP Laserjet 5 paper jam by traken (2/14/07 8:46 AM) reply | + / - | This seems to be an old thread but I have the paper jam error on a 5N, however, if I push down on the top center of the toner cartidge and hold it, things work fine, so I wedged something in there to do just that and all is well. My question is what should I be replacing, the side rails perhaps, or could it be the gears on that mesh with the toner are poorly aligned? I have tried another fuser no differance as well as other toners.
Thanks,

| Re: HP Laserjet 5 paper jam by moe (2/14/07 8:54 AM) reply | + / - | Where exactly is the leading edge of the paper stopping? There is a cartridge guide above the cartridge that serves to push it down. I have seen a few go missing, but when that happens, the page is blank.

Lets start all over and you need to be a lot more descriptive of the problem beyond the fact you have a paper jam. Start with when it started happening. What you might have done to cause it. Is it happening when you power the printer on or when you try to print? Does the motor run when you power it on? Don't leave anything out. I lose interest real quickly when people won't answer my questions and provide detailed information. I am not a psychic, I am a printer tech.

i picked this up at a yard sale for 5 bucks , figured it can't hurt and may be worth repairing.
as soon as i plug in the power cord , the printer initializes , goes to ready and then displays (remove paper jam) , i checked the springs and they are not stretched nor are any gears missing teeth.

| Re: HP Laserjet 5 paper jam by kayautho (4/10/08 8:55 PM) reply | + / - | My LJ5 was working fine until I added a duplexer. The sheet of paper goes about half way thru the fuser and jams accordian wise. The duplexer looks brand new. I tried feeding manually on paper tray 2 and the paper jams the same way. I also configured the duplexer off and the printer worked fine. Any help would be appreciated (moe?).
|
| Re: HP Laserjet 5 paper jam by moe (4/10/08 9:38 PM) reply | + / - | The ones that I have seen that cause problems like that were in the area of the "fingers". I've seen a few that had a broken finger or two and the paper would catch on them. I had one where there weren't any broken fingers, but I managed to make it work by putting some 3" clear tape across the fingers. Whatever works. I do have some working duplexers if you can't fix it.
|
| Re: HP Laserjet 5 paper jam by kayautho (4/10/08 11:41 PM) reply | + / - | Moe: I'm still working on it. It looks like the paper should get pushed out of the fuser and then lift the fingers slightly, slide under it and continue on until a power roller picks it up. It looks like mine stops at the fingers. You think the fingers might be misaligned? I believe that if it doesn't get out of the fuser within a given time, you get a jam indicator. In this connection, I thought it was an accordian jam but I see its actually wrinkled from the fuser heat. I have a good spare LJ5 which I set on top of the duplexer and that one jammed also. Where would you put the 3" tape?

| Re: HP Laserjet 5 paper jam by kayautho (4/11/08 7:27 AM) reply | + / - | Moe: (If you'r still hanging in there.) I see now where you put the tape. With the duplexer off, the fingers lie flat and guide the paper up to the regular printer path on top and exit. I taped the fingers up so there was a little space for the paper to slide under. And it did but after going up another few inches or so, it jammed again. I believe something mechanical is supposed to slightly lift the fingers allowing the paper to go up the passageway and then some rollers are supposed to grab the paper and partially push it it thru that letter slot in the back and then reverse and send the paper back down for a printing on the other side. I'm sorry to say that this is not a quick fix. This is something electrical. Probably a solenoid is not lifting the fingers and a motor is not turning the grabbing rollers.
What did you say about a useable duplexer in your shop?
Arthur
|
| Re: HP Laserjet 5 paper jam by moe (4/11/08 8:54 AM) reply | + / - | The one that I had sticking was because the paper was somehow hanging on a finger. Even under close examination, I couldn't see why. The tape was a last resort that worked. Whatever the paper was hanging on, the tape smoothed out and it passed over it. I was kind of surprised that it actually worked. I think I actually have a couple of the duplexers. I don't know how well they would survive shipping any kind of distance.

| Re: HP Laserjet 5 paper jam by kayautho (4/11/08 9:20 AM) reply | + / - | If you have one in operating condition, I'll pay, say, $25 plus UPS ground. If you accept, open it up flat, put it in a large plastic bag and a box with lots of squashed newspapers or peanuts would be better. If you can't do it - no problem. In fact, thanks for the help.

| Re: HP Laserjet 5 paper jam by nivek (10/22/08 7:19 AM) reply | + / - | As always check out the cartridge try another known good one if you have it. Ive seen alot off these though that have a cartridge guide that sits above the toner cartridge when its inside of the machine. Its a long black plastic piece that runs horizontal above the cartridge in the machine. It will often break and cause it to drop slightly and block the lasers path as it trys to write to the drum so feel on top of the machines cavity and see if theres any lose plastic just dont touch the fuser its above and before it. The machine also has a shutter that opens when the cartridge is installed or when the lid is closed I cant remember which actuates it. But if you remove the top cover you should be able to see its movement.
|
| Re: HP Laserjet 5 paper jam by StrayBit (10/22/08 11:01 AM) reply | + / - | It will NOT print out blank paper because "it will feed paper to the internal (below the toner cartridge) roller where it stops". That roller does NOT continue the paper movement because "this roller turns freely but the gear on the end does not". (Quotes are from my initial post!)
I don't have another cartridge.

| Re: HP Laserjet 5 paper jam by nivek (10/22/08 3:28 PM) reply | + / - | Sorry I was replying to the post below yours. I was not trying to help your problem given its over a month old. However if your talking about the black spongelike roller known as the transfer roller it should move freely and the black gear on the left side just to the left of the white plastic bushing should move with the roller, given the fact that it is driven by the toner cartridge. so pull the transfer roller out and see whats up with the gear or press it back onto the roller shaft. I would think though if the gear was in its right place and not moving your machine would let you know by grinding.
|
| Re: HP Laserjet 5 paper jam by StrayBit (10/22/08 4:05 PM) reply | + / - | Thanks, nivek. I'll have to figure out how to get that roller out. I didn't notice any way when I originally posted. And it has been so long, I doubt that I'll remember how to put it back together.

If not open the rear door and check there its probably stuck in the fuser unit. two screws at the bottom of the machine and it just pops out. Make sure you have it unplugged though and wait awhile becuase its extremely hot.

| Re: HP Laserjet 5 paper jam by laella (4/23/09 11:47 AM) reply | + / - | My LJ5 was working completely fine until today. I printed out something fine yesterday. When I went to print today, I looked down and noticed that there was no display on the screen. I checked to see if it was on and it was. After further searching, I realized that they back plug was loose (I'm a teacher and the kids come up to my desk a lot). So, when I pushed it back in, the printer started making that sound like it does when it is warming up or about to print. Then it started making this grinding/shaking noise and smelled like something was burning. Then the beloved "REMOVE PAPER JAM" flashed up. Usually, this occurs in the tray, but now it is in the compartment where I have to remove the ink cartrage to get the jam out. The paper is printed on about 5/6 of the way and waved up sort of like it couldn't get into the next part (?). But that last 1/6 of the page didn't make it out of the part before it. It's finally stopped making the rumbling sound when I try to print something- but this same jam occurs each time. When I remove the jam, it will try and print it out again and we are in the same place. I am not a printer tech or anything- so I do not know names of the parts. Any help would be great. Thanks!

| Re: HP Laserjet 5 paper jam by nivek (4/23/09 1:58 PM) reply | + / - | http://www.fixyourownprinter.com/kits/hp/K21
Fuser is just inside back door. Its the part that uses heat and pressure to bond the toner to the paper so let it cool alittle bit before touching or removing.
Sounds like the fuser drive gear is broke. Part is found at that link above. You also might want to pull the fuser out the back and make sure its still in good condition by visibly inspecting rollers, gears and making sure it rotates smoothly. Most the time the drive gear breaks with age but every once in awhile a worn fuser will help out with the breakage. Two screws on bottom metal just inside back door and the fuser pulls out and you can check that, also the gear that breaks can be checked with the fuser removed. Just look inside the machine where the fuser gear meshes with the internal ones. The small one closes to the rear of the machine is the one usually with the broken teeth.
|
| Re: HP Laserjet 5 paper jam by laella (4/23/09 2:48 PM) reply | + / - | Okay, I did that. I couldn't really tell if it was good or not. The things appeared to be rotating fine. I tried to rotate the gears inside and they were a little tough to rotate, especially the small one closest to the rear. It does appear that is the place of the jam, though. That little gear looks kind of old and yellowed. I couldn't tell about the teeth. It definitely had them, but not sure if they were more worn down as opposed to broken. Thanks for your help.
|
| Re: HP Laserjet 5 paper jam by nivek (4/23/09 4:34 PM) reply | + / - | Ok another way to tell if you have a broken gear is when the printer turns on or goes to print the top exit rollers should turn if they dont then once again you have a broken gear. My guess would be the gear in the kit. Im somewhat shocked you didnt see teeth missing but its definitly worn by the discolorization. The whole drive train is RG5-0876 if your unsure. Sorry I couldnt pin point foresure the source of the problem. And dont worry the gears inside should be tough to rotate its easier to rotate the larger ones to get the small one to move.
|
| Re: HP Laserjet 5 paper jam by moe (4/23/09 4:38 PM) reply | + / - | If you want to turn that little gear to examine it, the easy way to do so is to take out the toner cartridge. There is a large spiral gear inside the printer on the right side. A lot easier to turn that and it in turn will move that little gear that is suspect. Just replaced one today that was missing a few teeth.

| Re: HP Laserjet 5 paper jam by buddyscarlett (9/11/09 10:43 AM) reply | + / - | I have an HP Laserjet 5 that keeps saying remove paper jam although there isn't one. It does this only when printing legal paper through tray 3. My print jobs all have a mix of letter and legal paper (mortgage applications). It will print the letter size fine, then the first few legals, then it says remove printer jam. I will then open up the top and remove the toner and stick it back in, open up the back and close it, then it warms up and prints one legal page (the same one that it got "stuck" on before) and says remove paper jam again. Sometimes I get lucky and it will print two pages before I get the error so that I will end up with the next page that I need, but not usually and not before I kill 500 trees. I also note that the right hand side of my legal and letter sized papers are coming out with little creases on them. Not sure if it's related, but I don't think it used to to do this.
Thanks for any suggestions!

| Re: HP Laserjet 5 paper jam by moe (9/11/09 5:36 PM) reply | + / - | Try printing the legal from tray 1. Do you get the same problem?
As for the creases, the only thing that could cause creases is the fuser assy. That's the only place the paper is subjected to pressure.

| Re: HP Laserjet 5 paper jam by RJSparling (3/10/10 10:01 AM) reply | + / - | Hi Guys, I have a problem that I don't see elsewhere on the forums and a bit of a head-scratcher. On my LJ5 (not 5L or 5P or anything else) get a "Remove Paper Jam" error message. I open the back door and I see the paper exiting the fuser, running up betweeen the rollers and the top of the paper stops just on the front side of the paper guide fingers that extend downward, but it is not high enough to reach the upper exit roller. I remove the paper from beneath the guide fingers and pull the paper out, but there is no evidence of accordion. Now the odd thing about this jam is that it only does it when I use tray 1. Paper runs through the machine normally from tray 2 and tray 3. I have tried this with the same paper (20#) that I have loaded in the other trays and with envelopes. Do you have any experience with this problem?
|
| Re: HP Laserjet 5 paper jam by Tinker (3/11/10 6:47 AM) reply | + / - | To RJSparling,
I've had pretty good luck with rubber cleaners and conditioners. Clean the surface of the rollers in the back of the printer (just above where the paper stops.) Armorall used to put out a cleaner that was great, and there are some rejuvinators but it seems that lately they're all aerosols--not appropriate unless you just spray a q-tip and use it to wipe off the rollers.
Only use that on RUBBER rollers and the pickup rollers in the trays that have the wide band around them. (That can also fix mis-feeds.)
If that doesn't do it, check the gear teeth on the fuser. Fiber gears wear and loose teeth.
|
| Re: HP Laserjet 5 paper jam by moe (3/11/10 2:10 PM) reply | +1 + / - | Is the image on the page you feed from Tray 1 in registration? Also, watch the pickup roller and see if it turns more than 1 time. Take the plastic face plate off the front so you can watch it better. There's a pinch latch at the top of the plate and then just pull it off.
|
| Re: HP Laserjet 5 paper jam by RJSparling (3/11/10 11:14 PM) reply | + / - | @ Tinker - although I am sure those rollers could use more maintenance than I give them, I'm not sure that is the problem because paper feeds correctly through those areas when I print from Tray 2 and Tray 3.
@ Moe - I don't know what "in registration" means, but the image on that page that jams is clear, complete, and properly positioned. The pickup roller turns 1 time to feed the paper. The next set of rollers (oblique?) take the paper from there.
After I posted my question I downloaded the service manual from your site (thank you!) and skimmed through it. The last paragraph on page 7-20 seems to implicate the PS5 paper end sensor. If I understand correctly, PS5 is needed only on tray 1 to sense the end of paper as a means of determining the paper length. A faulty sensor never sees the end of the paper, so it times out and assumes a paper jam which stops the printer. Just so happens that it stops the printer with the page in the position I have described. What do you guys think?

| Re: HP Laserjet 5 paper jam by JoVo (3/13/10 3:46 AM) reply | + / - | I didn't know whether to say I'm a printer user or a technician.. Though not professionally trained, I am responsible for operating, maintaining and repairing a good number of printers.
I'm having trouble with duplex jams with a 5m.. the jam occurs just as the paper leaves the back side of the duplexer and enters the bottom horizontal return path. It doesn't occur every time but about half the time... I cleaned the pinching rollers that guide it along that path... there seems to be an issue that intermittently keeps the pinch rollers from activating at the proper time.

As a beginning I suggest downloading a copy of the service manual that Moe so generously provides. The duplex operation is discussed beginning on page A3. Maybe after reading through it you could give a better description of what is happening. Good luck!
