HP DJ500 Problem

   Hello,
   yesterday eventually the head-moving motor of my HP Deskjet 500 ran hot
   and in effect either the motor of the carriage or its controller are out 
   of order, the printer completely turns off, if he's trying to move the 
   carriage to the resting position (because he has to drive up that tiny 
   rubber-cap a little hill). Without the head installed the printer stops
   working, complaining about paper-jam.
   Two questions:

   -- the problem arose while the printer was idle and attached to an
      OS/2-running compatible with the beta-test-DJ-driver from IBM installed.
      I experienced various software Problems with it, has anyone experienced
      hardware problems (perhaps like the above)?
   -- has anyone experience in fixing such motor-troubles or information about
      the controlling technique used by HP in the DJ500 (It's a TI 298KV
      controller, but I cannot figure out how the sense signals are 
      connencted).

  Thanks in advance,
  MC
