C03## Master Board/Harness Malfunctions
•
The copier performs a self-diagnostic sequence to determine if the microprocessor out-
puts a signal to each of the IC ports on Master Board PWB-A properly. It is intended for
detecting the following malfunctions (C03##).
•
Any malfunction is detected when the “Controller Board Check” available from the “I/O
Check” function of the Tech. Rep. mode is executed.
•
If the microprocessor fails to output any of these signals or if any of the electronic compo-
nents on the board (driver IC, etc.) is faulty, the copier determines that there is a faulty
condition existing and shows the corresponding malfunction code on the Touch Panel.
•
C0350, C0351 or C0352 is displayed when there is a communication fault between the
copier and paper feeder option or Duplex Unit, and is detected as an isolated malfunction
when the Power Switch is turned ON.
