Paper Jams

Paper Jams; copiers, fax, printers

Here is a problem that is universal.   First we will try to determine where the jam is occurring.  Make 1 copy or print at a time until you find where the jam is happening.  If you make multiple copies/prints you will be deceived and be looking in an area that isn’t causing the issue.  If it is jamming at the paper feed area,  remove all of the paper  and look for folded or torn paper.  Fan the paper and square the paper up and install it in the tray nicely.   Too many times I have seen paper installed half- hazerdly and cause the jamming.  If  the tray is Brocken or the copier /printer thinks it is a different size can also cause jamming.   Now,  if none of those are causing the problem the best thing to do is to replace the feed rollers, or at least clean them.   You should use Soapy water or also try WD-40 it works well, but never Alcohol it will dry out the tread on your rollers.    Replace them if the tread is worn is really the best way to do it.

If it is jamming in the exit or fuser assembly can be caused by five things.
Bad separation fingers ; These can also be called; Separation Claws, Scrapers, Pick off Pawls.  The fingers are small ceramic claws that ride against the upper roller.   They are normally spring  loaded.  When these go bad it will do an accordion type of jam.  They could be worn , broken or out of position.  There  is normally a spring on them for pressure to the upper heat roller.

  1. Bad heat rollers; The teflon coating will wear off and the paper will stick and cause jamming.
  2. Brocken gear(s); If the gear is broken the paper can’t get through.
  3. Sensor or sensor lever flag; This should be the last thing you check, uncommon fault.  Test with simulations , multi meter or replace with known good sensor.
  4. Dirty Fuser entrance guide;  This will cause wrinkling, creases in paper and  jamming.

It could be many other things that is causing the jamming issue but when you have a paper jamming problem I always begin with the feed. This is the primary start point for the paper path. Always keep it simple. Begin with making one copy or print at a time to determine where the problem lies. Try cleaning the rubber good first with wd-40 or replacing the rollers if you have them.
