    Paper jam at the fuser part

  • Anonymous Mar 29, 2014

    My paper jams are in the fuser and on the transfer unit. It has been about 9 months since I replaced the transfer unit for the first time after 8 years of use.

1. Faulty/blocked fuser exit sensor or faulty/blocked POB sensor. The printer thinks paper is present at one of these sensors when there should not be paper present
Verify that the fuser exit sensor is not stuck
If both sensors are working correctly, the most likely cause is the POB sensor is being blocked by the transfer unit. This can happen if the sensor is out of position, or if the transfer unit's white plastic baffle is out of position. Try bending the POB sensor bracket outward slightly to clear the baffle and retest.

The error 010-311 appeared. i reseated the fuser unit several times. no success. any ideas?


Hi Anonymous,
If you have a spare Fuser Unit I would suspect you install that and try it.
Have you had a jam in the fuser in the past in which case check the paper sensors are working correctly by activating them with a sliver of paper.
I have known the exit sensor to be jammed and only when you remove the exit transfer unit to the finisher will it be obvious.
If that is a but daunting then you might need to call in Xerox.
Good Luck.

How do i fix the little black piece that broke off of the fuser exit sensor on my Xante Ilumina?


Amanda,
The problem is related to the paper exit assy. Their is no problem with your fuser assy. Take a look at the exit document related to your problem. Usually that is cause when removing a paper jam, that switch flags break for pulling the paper in the back direction. You would have to replace the paper out exit swicth black actuator.

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!

I have a Lexmark t644 Jamming!


If it jamms passing the fuser you have to check the exit sensor, there are 2 sensor at fuser exit, you can see them taking off the rear cover, one is for paper size and the other is for paper jams, check them both or replace them.

If it jams before the sheet passes the fuser it may a sensor in the black plate under the cartridge, or the pass rollers at the left side of the printer.

Before everythig try cleaning them with an air compressor or with an spray cleaner with isopropilic alcohol.

Hope it helps you...

Sharp-275 Not a simple paper jam


This sounds like you may have a bad jam detect sensor, there is a sensor on the exit end of the fuser on the right and the flag for this is located in the middle of the exit guide on the fuser this gives us most of those types of jams.

Hope that helps...
