(14)To take the paper feed chute off the platen frame, do the following:

-Disconnect the main-sensor harness from the sensor PCB while pressing down the PCB with your finger, then remove the harness guide and take out the harness from the cable clamps.

NOTE: Pulling up the main-sensor harness without pressing down the sensor PCB will cause the PCB to work out of the paper feed chute.

NOTE: Once removed, the harness guide will become unusable and a new one will have to be put back in.
