   There are various plastic "paddle" sensors along the paper path that   
   are used to detect paper jams or misfeeds.  If the rubber paper feed   
   roller slips slightly when trying to feet a page, the printer will   
   detect that the paper is "late".  The printer then declares a paper   
   jam.  If it correctly feeds a few pages, but then jams, my guess would   
   be the same as the other Jeff's.  You might have lint, dust, clay   
   paper coating, loose toner, shreded paper, insects, etc that are   
   causing the rubber rollers to slip on the paper.   
      
   For the CP1515, it's likely that the rubber has been polished smooth   
   by the slightly abrasive paper.  That will also make the roller slip.   
   Try removing the rubber part of the roller from the plastic drum and   
   flipping it over.  That should give the roller a 2nd life.  However,   
   what works every time is to purchase and install a rebuild kit.  At a   
   minimum, you need at least the feed roller RM1-4426 and the separation   
   roller RM1-4425. For example:   
      
      
   I can think of a few uncommon failures that might cause a paper jam   
   indication.  Try roller cleaning and replacement before we go down the   
   rabbit hole.
