Action
Check the ac voltage. If the line voltage is incorrect,
inform the customer.
Inspect the cord for damage. If it is OK, check the
continuity.
Remove the power supply. Check the continuity of
the fuse. Install the power supply.
There is no check you can make of the power sup-
ply while it is removed from the machine.
Check the exit sensor flag for correct operation.
The printer will not turn on unless the flag is pass-
ing through the sensor.
Check the connector pins on the interconnect
board where the power supply plugs in. These pins
may be bent.
Remove the controller board. Turn the printer on. If
the Ready LED comes on, turn off the printer.
Remove any options plugged into the controller
board and re-install the controller board. Turn the
printer on. If the machine powers up normally, one
of the options is defective. Re-install each option
one at a time to determine which one is defective. If
the machine did not power up normally when you
re-installed the controller board, replace the con-
troller board.
