Printhead
Printhead cable
HVPS board
LVPS board
Engine board (E320/E322)
Controller card (E220/E321/E323)
Blank pages can be caused by a
defective printhead assembly, HVPS,
LVPS, engine board (E320/E322) or
controller card
(E220/E321/E323).
• Printhead errors typically result in
printer service errors.
• Blank pages typically are caused
by the PC roll not being properly
charged.
Unplug the printer and check
continuity between the HVPS solder
pads marked DC (below fan) and the
corresponding pin inside the printer.
• If there is not continuity, remove
the HVPS and clean/replace
springs.
Try a different cartridge. If it fails,
replace the HVPS.
