Fatal Error Code 13: HCPP Driver Error
This error occurs when the Mechanism Control ASIC detects that a
single phase of the HCPP motor was energized for longer than the
allowed period of time. This indicates a malfunction of either the HCPP
motor, or ROM Board driver circuitry, or both.
Check and replace both of the following, and replace all malfunctioning
parts. Do not replace the motor until the driver circuitry has been tested.
1. HCPP MOTOR (p.168).
2. ROM BOARD (p.137).
Fatal Error Code 14: HCPP Error
This error is indicated when the HCPP Sensor detects that the paper
paths do not switch during a paper path switching operation.
Check the following in the order below, testing functionality at each
step. If either the HCPP motor or driver circuit on the ROM Board have
failed, always check both before installing the replacement part.
1. Check connectors CNSEN1 (PPSS signal input) and CNSEN2 (drive
signal output) on the ROM Board. See
2. Check the HCPP sensor connector CNPPSS on the Sensor Board.
See Figure 4-10 on page 137.
3. Check the HCPP Sensor.
4. Check the HCPP motor and the HCPP driver circuit on the ROM
board. Replace the HCPP MOTOR (p.168)
(p.137).

Fatal Error Code 15: OC Driver Error
This error occurs when the Mechanism Control ASIC detects that a
single phase of the OC Motor was energized for longer than the allowed
period of time. This indicates a malfunction of either the HCPP motor,
or ROM Board driver circuitry (TA10: STA485A), or both.
1. Check OC motor connector CNO/C on the Sensor Board. See
4-10 on page 137.
2. Check both the OC motor and the OC motor driver circuitry on the
ROM Board. To replace the ROM BOARD, See
BOARD (p.137). If necessary, replace the
Fatal Error Code 16: OC Error
This error is indicated when the Mechanism Control ASIC determines
that the Roller unit failed to open or close. This error is caused by a
sensor failure (OC Sensor 1 or OC Sensor 2), an OC motor failure, or an
OC motor driver circuit failure.
Check the following in the order below, testing functionality at each
step. Check both the OC motor and OC motor driver circuit before
replacing either, since a failure in one can cause a failure in the other.
1. Check connectors CNOCS1, CNOCS2, and CNO/C on the Sensor
Board. See Figure 4-13 on page
2. Check connectors CNSEN1 (OC Sensor 1/ OC Sensor 2 signal
input) and CNSEN2 (drive signal output) on the ROM Board. See
Figure 4-10 on page 137.
3. Check both the OC driver circuit and OC motor before replacing
either, since a failure in one can cause a failure in the other. If
necessary, replace the OC MOTOR
or both.
