Check for cartridge damage. Blank pages can be caused by a defective printhead assembly, LVPS/HVPS, or controller card. • Printhead errors typically result in printer service errors. • 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 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.
