Print quality service checks
Note:
Ensure the cover closes tightly. A gap in the opening may allow light to expose the photoconductor,
resulting in a ‘dirty’ print. Extreme environmental conditions, temperatures, and humidity will affect the print
quality.

Blank page
FRU
Action
Toner cartridge (not a
FRU)
Remove the toner cartridge, and gently shake it to evenly distribute the toner.
Check for cartridge damage.
Printhead
LVPS/HVPS
Controller board
Blank pages can be caused by a defective printhead assembly,
LVPS/HVPS, or controller board.
• Printhead errors typically result in printer service errors unless there is blockage of the
beam or dust on the lens. Check the lens and opening for blockage.
• Blank pages typically are caused by the PC roll not being properly charged. Try a
different PC kit.
• With the cartridge out, check the spring loaded contacts on the right side for free motion.
None should be ground except for #4 contact from the front.
Unplug the printer, and check the cable continuity between the LVPS/HVPS connector
marked OPC (at CN202) and the corresponding wire form (spring) found about 14 mm
above and to the right of the transfer roll gear.
• If there is not continuity, then call the next level of service.
Try a different toner cartridge and PC kit.
• If those fail, then replace the LVPS/HVPS, controller board, or the printhead in that
order.
