Service Manual

Inspect the printhead shutter for proper operation and make sure the 
actuator on top of the cartridge is present and extends into the 
printhead shroud when the printer top cover is closed. A failed 
printhead will cause a 931 Service error rather than blank output.

Check the continuity of the HVPS cable. The HVPS and transfer roll 
contacts should be clean and spring back when pressed. Make sure 
the transfer roll contact under the left bearing is making contact with 
the HVPS.

Make the following voltage checks while running the print test 
continuously and again while idling.
