Dead machine service check
A dead machine 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 high-capacity input tray is installed, remove the option and check the base printer for correct
operation. If the base printer operates correctly, go to
“High-capacity feeder input tray service
check” on page 2-56
. If the base printer continues to not operate correctly, remove any other
attached paper handling options.
Warning: Observe all necessary ESD precautions when removing and handling the system board
or any installed option cards or assemblies. See
“Handling ESD-sensitive parts” on
page 4-1

caution if the printer must receive power in order to perform the task.
Remove any input and output paper handling options from the printer.
