Dead printer service check
A dead printer is a condition where the display is blank, the LED on the operator panel is off, no fans turn, no
motors turn, and the fuser lamp does not come on.
If a 500-sheet option assembly (C52x models) or a 550-sheet option assembly (C53x models) is installed,
remove the option and check the base printer for correct operation. If the base printer operates correctly, replace
the 500-sheet option assembly.
Warning:
Observe all necessary ESD precautions when removing and handling the system card or any
installed option cards or assemblies. See
“Handling ESD-sensitive parts” on page 4-1
.
Remove any input and output paper handling options from the printer.
