Sc996 No Input From The Horizontal Encoder Sensor; Sc997 Horizontal Encoder Abnormal; Sc999 Maintenance Stepper Motor Out Of Position - Ricoh J001 Service Manual

3. Replace encoder sensor.
4. Replace vertical motor.

SC996 No input from the horizontal encoder sensor

Description: The input from the horizontal encoder sensor could not be detected.
Probable Cause: No input from horizontal encoder sensor, encoder sensor signal did not
change, encoder strip is dirty or scratched, horizontal motor not rotating.
Location: Encoder film strip, horizontal motor, control board, encoder sensor
Procedure:
1. Cycle printer on/off, check result.
2. Confirm film encoder not loose.
3. Replace horizontal motor.

SC997 Horizontal encoder abnormal

Description: One of the following:
The horizontal motor switched on at power on so the horizontal encoder sensor could
detect any foreign matter on the horizontal encoder strip but the motor could not switch
off.
When the printer was turned on, or after it left the energy save mode, the horizontal
motor could not stop when it was seeking the home position.
Probable Cause: Encoder sensor signal did not change, or encoder strip is dirty or
scratched.
Location: Encoder film strip, control board, encoder sensor
Procedure:
1. Cycle printer on/off, check result.
2. Replace encoder sensor.
3. Check encoder film position.
4. Check carriage FFC (Flat Film Connector).

SC999 Maintenance stepper motor out of position

Description: Maintenance HP sensor motor failed to detect the motor position even though
the motor was rotating.
Probable Cause: Maintenance motor not rotating, maintenance motor HP sensor signal did
not change, cap did not separate from carriage.
Location: Maintenance unit, control board
