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 card
Blank pages can be caused by a defective printhead assembly,
LVPS/HVPS, or controller card.
• Printhead errors typically result in printer service errors unless there is blockage of the
beam or dust on the lens.
• Blank pages typically are caused by the PC roll not being properly charged. Try a
different PC kit.
Unplug the printer, and check the cable continuity between the LVPS/HVPS connector
marked OPC (at PCN 2) 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, call the next level of service.
Try a different toner cartridge and PC kit.
• If those fail, replace the LVPS/HVPS, controller card, or the printhead in that order.
