Dead printer service check
A dead printer is one which, when powered on from a known good electrical outlet, displays no indication of power to
the printer by changes to the LCD, LED, or any movement of the fan or motors. If the printer appears dead but makes
a beeping sound, check the operator panel. See
“Operator panel (displays all diamonds, no beeps, or five beeps)
service check” on page 131.
If a 650-sheet Duo Drawer is installed, then remove the option and check the base printer for correct operation. If the
base printer operates correctly, replace the 650-sheet Duo Drawer.
