Cover closed switch/cable service check
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 2-96
. 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:
When you see this symbol, there is a danger from hazardous voltage in the area of the
printer where you are working. Unplug the printer before you begin, or use caution if the printer must
receive power in order to perform the task.
Remove any input and output paper handling options from the printer.

Cover closed switch/cable
assembly
Check the cover closed switch for proper mechanical operation. If
incorrect, repair as necessary. Disconnect the cover closed switch
cable from J8 at the system board and measure the voltage at J8-3.
It measures approxi5 V dc. If the voltage is incorrect, replace
the system board. If the voltage is correct, check the voltage at J8-1.
If the voltage measures greater than +1.0 V dc, replace the system
board. If the voltage is correct, check the continuity between J8-1
and J8-3 on the cable. If no change in continuity occurs as the switch
is activated, replace the cover open switch/cable assembly. If the
continuity changes as the switch is activated, replace the system
board.
