Where is the area that is flat ending up when it gets stuck?

Also, what repair was made on this printer? DId you take out the motor at all?

Also, if you removed the side panel.. is the clutch correctly placed? And is the spring in there?

Also, be sure to align the clutch on the pickup roller shaft with the follower (large plastic tab) (callout 2) on the paper lift plate

No paper pickup, Press check


1. Push the paper far inside / use the priority tray.
2. Check for deterioration of the rubber on the main pickup roller (Replace if needed).
3. Ensure that the main paper pickup roller (view inside the printer from the priority input slot - use a torchlight) is rotating when print command is given / 'check' button is pressed after the error message.
4. The printer will make three attempts, one after the other, to pickup the paper (you should be able to hear the sound of main motor and gear train rotating - if no sound is heard the main motor / gear train is bad).
5. If the paper pickup roller does not rotate - a component in the gear train needs attention / replacement.
6. The gear train is behind the formatter inside the right side cover.
7. Service manual can be downloaded free on the net.

Hp 4L printer won't pickup paper from tray. Sequence- green led light- motor running but with grinding- no movement from pickup roller or foot- finally a misfeed led light.


That is a very common problem with the Laserjet 4L and 4P printers. The sound you hear is caused by a broken motor drive gear. This is a small plastic gear on the drive motor shaft. They can develop a small crack which prevents the motor from turning the gears for paper pickup and toner movement. When the motor tries to turn the broken gear can not turn the other gears and makes the popping or grinding sound when the gear teeth slip. You will need to replace the motor gear, it is available here:

Printer error 59.99


This could be the problem / answer.

0.gif Re: 3500 giving 59.99 error *SOLVED!* by alkemyst (4/10/08 8:16 AM) reply + / - I was reading about the error and another user had an issue with the swing guide plastic falling into the pickup assembly...the swing arm on this printer has in similar shape with the plastic being brittle (I had to use new larger self-tapping screws to fix it properly).

I did this this morning, it only took about 20 mins and was my first time doing this beyond the swingarm guide and removing the Image Drive assembly which gave me some practice :). It's really an easy job IMHO if you have the HP manual downloaded.

Took off the right cover, the right swing arm, left swing arm (probably not needed), the swing rod guide, the unclipped the harnesses on the pick up/feed assembly as well as unloomed the harness and the 5 screws that hold it. Then two more on the solenoid behind it and a cable or two...then that gear that was right off the solenoid had a visible offending piece of plastic, this step is page 224 in the repair manual, steps 16-19 ish, the double gear assembly that is there when you remove the pickup solenoid had the sliver of plastic from the swing arm assembly between the two gears.

Prints great again. The swing arm assembly seems to be falling apart on alot of these...may explain the large amount of 59.99 errors being reported lately.

Paper won't pick up, printer makes grinding noise


Hello,

The problem you are discribing is caused by a broken gear on the drive motor. The small gear cracks after years of printing and will jam the pickup assembly, the sound you hear is the motor trying to force the gear assembly to turn. We have a repair kit with the gear and instructions available for $12.95 including shipping if you want to do the repair yourself. The job should take about 30-45 minutes even if you are not a printer tech. I hope this helps.

My HP laserjet 1200 is making a terrible noise when printing - do you have to oil the rollers?


No Please don't oil any part of the printer, oiling may damage the complete printer first check if the nopise is coming from rear, Top, Front or side.
If noise is coming from Top than possibly top outbin roller are making noise.
If side tham may be toner cartridge or cartridge motor is making.
If noise is coming from rear than either fuser or the gear which rotates the fuser are making noise.
If noise is coming from from than Tray 2 pickup assembly or faulty tray is making noise possibly faulty registration assembly can also mak noise none of the part should be oiled only the faulty part should be replaced.

13 Paper Jam - but there is no paper inside!


I have a long solution (possibly) to your issue:

Error 13 Paper Jam
  • Paper jams can occur in 3 places: Entry, registration and exit.
  • If the paper isn't picking up out of the paper tray, visually inspect the pickup roller. If it looks shiny, replace it. You should also replace the separation pad as they work together. On the 4L/4P/5P/6P the pickup roller has a plastic shaft that breaks. You'll have to replace the whole pickup assembly. This requires major disassembly of the printer. Check our printer repair kits for your model printer. If you don't see it listed, email us.
  • If you have an HP 4/4+/5 with an optional 500 sheet feeder that's jamming, check the balance knob adjustment. Center it with a full **** of paper for proper operation.
  • If the paper is jamming at registration or anywhere between pickup and exit it could be a number of things. Check the paper path for torn bits of paper or label residue. On the II/III series, remove the metal registration guide plate (2 screws) and check underneath it. If the pickup rollers are moderately worn, the paper will stop just short of the registration roller. On the 4L/4P/5P/6P remove the screw holding the oblique roller assembly (Inside front of printer) and pull out and inspect the assembly and the area under it. On the HP 4/4+/5 pivot up the metal plate and check underneath it. Check the roller assembly on the left side for torn scraps of paper (a flashlight or torch is necessary).
  • Make sure paper cassettes are firmly seated, corner tabs aren't bent. Some trays have lifting springs that could pop out if tray has been dropped.
  • On HP IIP/IIP+/IIIP printers if the paper scrunches up at the toner cartridge you'll need our Inside Accordion Jam Repair Kit.
  • Check your software settings in the program you are attempting to print from. Do you have the correct paper size specified? If you have a different paper size than what is in the tray, you'll get a paper jam.
  • Exit jams are frequently caused by exit sensors. These sensors are typically mounted on the fuser assembly or adjacent to it. They are plastic arms that block and unblock an optical sensor. The arms can get stuck or knocked out of place when clearing paper jams. The optical sensors can also get dirt blocking the photo cell. Clean the sensor and check for free movement and proper installation of the sensor arms.
  • On HP II/III series exit jams are mostly caused by worn gears. The best way to troubleshoot this is to defeat the door interlock (see door interlock photo on troubleshooting page). Press down on the arm on the top right of the fuser. Initiate a test page. While holding down the arm, press one of the metal cartridge detect switches just below the door interlock. Watch the movement of the gears. You will get a 51 error because the door is open. Recycle power to get rid of error. There is an arm gear on the lower right of the fuser that can shed teeth. There is also a 14 tooth gear below the large gear on top of the fuser. You can also manually rotate the large gear and check for binding or crunching. If that happens, then replace the 14 tooth gear. On the door, there are some delivery coupler gears that mate with the fuser and drive the exit roller. Check the gears for excessive wear. Replace if necessary. If the paper gets almost all the way out and jams, replace the exit roller or the exit roller assembly. If the error occurs after fuser replacement, check and see if the connector on the left of the fuser is properly mated with the one in the printer.
  • On HP IIP/IIP+/IIIP printers if the paper has accordion folds on the bottom and jams on exit, order our Top Output Accordion Jam Repair Kit.
  • On HP 4/4+/5 printers the most common cause of exit jams is the exit assembly. Order our 4/4+/5 Exit Jam Repair Kit. Exit jams in the fuser can be caused by a broken fuser drive gear or a broken gear on the fuser. Remove the fuser and check the gear inside the printer for broken teeth. Manually turn the gears on the fuser and check for smooth operation. Check the paper exit sensor arm for proper mounting and free movement.
  • Check to make sure the rear door is closed on the printer. Open doors can cause 13 paper jam indications.
  • On the 5L/6L check the registration sensor arm below the pickup roller. Also check the exit sensor arm (bottom center of the fuser). These arms frequently get stuck or dislodged clearing paper jams. On these printers, if you are experiencing frequent paper jams, order our 5L/6L Multi-Sheet/No Feed Repair Kit
All this comes from:

Good luck with it, I love the HP LaserJet 4 series of printers. I used to warm my coffee on the top of the fuser when I was doing large print jobs :-)

If this information helps, please give me a rating, thanks!

Paper pickup in tray 2 not working


This is an issue i've seen many times.

The gear that drives the lower tray barely conacts the gear in the main body.

You cannot buy just the gears, you will have to buy a new option cassette assembly.

If you lift the printer off of the lower cassette you'll see the suspect gears.

HP Laserjet 4100 series , paper jam output tray.( on top of the printer ). The roller under the topcover is turning the wrong way. The paper can't get out of the printer, and jams between the upper roller...


Hi F_bulsara,
First thing to try is to flip the paper over in the input tray. There are 2 sides to paper. One side may curl a bit too much due to heat of the fuser and get caught near the output rollers.

Unless the Output Assembly was assembled wrong, it is impossible for the rollers to turn the wrong way. The gear in the fuser drives the output assembly. The top rollers are rolling out.
If the rollers are not rolling, then one of the gears must be broken or missing. The output rolllers might need cleaning.

Next check the fuser unit. Disconnect power to printer and turn printer round. Remove the back output tray and the two small covers (left and right). Undo the 2 screws that hold the fuser in place. Pull the fuser out. Check the gears on side of the fuser. A broken gear in the fuser could cause this problem.

Continuous Paper Pick Up


Paper pickup solenoid plunger out of position remove covers locate solenoid on the right hand side of machine as looking from behind( Could be the other side as not got machine in front of me) and check that the plunger is in its correct position. If not refit replace covers and check.

Note sometimes the plunger falls to the bottom of the printer loosing the tension spring. What causes the problem you have is that the plunger does not lock the pickup gear into position and the engine drives that pickup gear all the time causing to pickup paper all the time.

Thanks Jason
