Action
Check the input sensor flag for proper position and
operation. The flag is visible if you open the manual
feed tray. The position of the flag should be in the
paper path such that when printing, the paper
pushes the flag down. Replace the flag if it is dam-
aged.
The input sensor is mounted on the interconnect
board. The sensor flag swings through the sensor
as the paper makes contact with the flag. If it is
operating correctly, replace the following FRUs in
the order shown:
1. Interconnect Board
2. Engine Board
