    There is an out of paper sensor (OOPS) plastic lever that operates when there is paper passing through. The OOPS works by the paper pushing a little flag up into an optical sensor. The flag sometimes gets stuck in the up position, into the optical sensor, tricking the printer into thinking there is a jam. Remove the back cover and look up and you will see some black plastic parts and the U-shaped optical sensor. The OOPS flag lever should move freely less than 1/8" travel. One of the little pivot shafts may have come out of the holder.

  1. Turn the printer off and open the access cover.
  2. Look for any obstructions in the paper path and remove them if necessary. (It is possible to move the carrier assembly with the power off.)
  3. Turn the printer on, load some paper, and press the Form Feed button.
  4. Watch the paper as it feeds through and try to determine where the jam is occurring.
  5. Check to see if all the rollers are turning.

    If all the rollers are turning, there may be something in the feed path that you can't see. Go to step 6.
    If not, there is probably a feed motor or a gear problem and the printer may require service.
  6. If the paper is jamming under the carrier assembly, you may be able to fix it using the manual feed slot.
  7. Turn the printer off.
  8. Take a #10 envelope and feed it through the left side of the manual feed slot until it comes right through the printer to the back of the exit rollers.
  9. Move it up and down first, and then slowly move it over to the right side. If something is stuck under the black guide plate, this may work it loose.
Good luck...

Canon Imageclass MF4370dn constant paper jam errors


Dear
Inside the back panel there are paper sensors attached to lever, a small spring connected to lever to keep its home position, the spring may dislocated from its position or the lever sticked to the base. some times a small piece of paper sticked at this may cause the problem.
Thanks.

Paper Jam but not really???


If it's a brand new printer, try removing and reinstalling the printhead. An incorrectly installed printhead will give you a false paper jam error.

Hp 2355 all in one error message


reset to factory defaults, also check the whole printer for paper jams. A paper jam can often casue smaller pieces to get stuck in gears or rollers. The message about opening and closing the lid is how the printer knows you went in to check it and closeing it triggers it to try again. If thers still a jam it will keep giving the message. The fist jam was caused by something, check and make sure there isnt any pieces of plastic broken off inside. If it has a rear access panel, check there also.
