Question about HP LaserJet 4L Printer

Open Question

Hello, My HP 4L printer is not consistent with the paper jam problems, it often stops at the first take up roller, it also stops after entry while being squarely positioned before it reaches the toner drum, it sometime stops halfway during the output on the document tray having only fused only part of the page. I Have carefully looked at the gear worm on the drive motor, other than a hairline crack at the shaft end, it looks very much in operating order and (it seems still fastened to the shaft) since the pickup gear is quite a distance from it, I checked all th sensor arms and their all O.K. I have placed a new original toner cartridge as well. I have tried better quality paper. I have reset using both the top and the side engine reset. Finally, I don't want to purchase a new motor and waste my money if I then have been left no choice but to have a repair technician fix it.

Thhis error is usually due to a dirty photcell (sensor) in the tray 2 paper feed assembly or a broken sensor flag in the same assembly. Start be removing all cartridges and the transfer belt. Look in the bottom of the printer below the lowest cartridge slot for a removeable cover. That's the area your problem is probably in. I have incuded a link to a free PDF of complete service manual below. Good luck.

Clear the printer queue on the computer (double-click the printer icon in the tray or in the Printers and Faxes folder and cancel all documents listed). Then power off the printer and disconnect the power - remove the paper from the paper tray until you have the printer memory cleared as to not waste paper.

Hp Lazerjet 4L constant paper jams


These machines can be problematic. They are old. Pick up rollers is the common issue. Remove the tray and look up into the machine and you will see the rollers. If they have a slick place on them, replacing them will probably solve your problem. Also make sure the paper path is clean from any paper dusk and or small bits of paper. Doesn't take much to cause a jam.

HP LJ 4L paper jam light flashes indicating a peper jam after printer makes a grinding noise. What can be the problem?


You may be right about the worn gear as a factor but I used to have a LJ 4 and whenever it indicated a paper jam it was always right. In some cases, the jam was a tiny scrap of paper deep inside. It took a flashlight and examination of every bit of the paper path to find it

Constant paper jam. Jams at wheel just as paper starts to go in. I have taken apart what I can and see no issues.


I'm having the same problem with my trusty and work horse LaserJet 4L. I've checked to make sure the corners of the stack are under the metal clips, I've made sure the paper size guide is securely in the proper notch. I can NOT make sure the paper is pushed down to the bottom of the cassette. It doesn't stay there - could that be the problem? Or perhaps something with the wheel/roller on the left (just as the paper goes in)? Ideas? Help much appreciated.

Consistent paper jam near paper entry point. sometimes it doesn't even leave the paper tray just stops there.


You need to clean the rubber roller that feeds paper, unplug the printer, tip up on the back with paper tray out, use a damp rag to clean the 1 or 2 rollers that are just above where the paper sits inside.

HP 4L printer indicates no paper when the tray has


When you removed the paper jam, was the paper torn? If so, did you ensure that you found all the pieces. (Put the piece of paper back together like a puzzle to verify). There could be a piece of paper stuck in the printer that is causing the paper sensor to fail.
The other possibility is that when you removed the paper jam, something became dislodged in the printer. Forcefully removing paper from the printer can cause this.

Have a hp laserjet 4l paper jam problem.No paper is jamed inside.Press the reset button,goes through its cycle process. See the D shape roller sensor working,but no paper is being pick-up.Hear a funny...


I have had a similar problem. The 4L has an inherent fault in the motor drive gear. It is made of nylon and has probably developed a hair line crack. As a result the gear slips when the printer starts up and tries to feed paper. I have replaced this part some years ago by replacing the whole motor and gear. I did find the replacement parts on eBay today. Here's the url:

http://stores.shop.ebay.com/Laserprinterkits-Printer-Repair__W0QQ_armrsZ1QQ_fsubZ4

The manual is also on line at another place. But when you order the parts you get a manual on CD. I am not the guy selling the parts but need them too that's how I found them.

Good luck.

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

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!
