Plotter displays: SERVO INIT ERROR message on power-up.

A.    Check for obstructions which might not allow the carriage to move left-
      to-right and grit drum roller to rotate.
       
B.    Examine the pinch rollers.

      1.    Turn off power to plotter.

      2.    Unclamp the pinch rollers. 

      3.    Remove media from plotter. 

      4.    Verify that pinch rollers move freely. Clean, if necessary.

      5.    Turn on plotter power.

      6.    Reload media into plotter.

C.    If the customer hears a grinding noise, a servo motor may be binding or
      there is an incorrect power being supplied to the circuitry.  It may
      also be that the service (cleaning) station is mounted too high.  
      None of these are user serviceable.  On Site service is required.

D.    If the servo motor wiring connector cables are not making a good
      connection, then they can be simply reconnected. The connections are
      all under the right end bell. If the customer is proficient, then they
      may perform the following steps:
      
      1.    Unplug the power cord from the plotter.
      
      2.    Remove the right end bell (there are four screws underneath the
            right end bell and two on the back which connect to the y-axis
            cover plate).
      
      3.    Press on each connector to ensure that each connector is tight.
      
      4.    Reattach the right end bell.
      
      5.    Plug in the power cord.

Some indications of a bad power supply:
