Print quality—solid color page
Service tip: A solid color page is generally caused by a problem in the high voltage system or an incorrect high
voltage in the printing process resulting in toner development on the entire photoconductor drum.
Step Questions / actions Yes No

in question.
Does this fix the problem?
Problem solved. Go to step 2.

Check the high voltage contact from the
HVPS to the photoconductor charge roll.
Ensure the contact springs are properly
mounted and that the charge roll contact
spring is making good contact with the HPVS
spring that runs through the left printer frame
to view the proper mounting and for removal
procedures.
