Epson SC-P800

• Code: 1123
• Description: CR Duty over error
• Causes: The load on the CR motor has exceeded the expected level.P
  • Paper jam (such as paper left on the print path)
  • Increase of load (such as the damaged CR shaft, damaged CR shaft bearing, insufficient grease, the deformed CR sub shaft)
  • CR motor failure (cable failure)
  • CR encoder failure (cable failure)
• Remedy: Visually check whether paper is left on the print path, and remove it if left.
  1. Replace the CR scale.
  2. Replace the driven pulley.
  3. Replace the CR motor.
  4. Lubricate the OIL PAD of the CR unit.
  5. Replace the CR timing belt.
  6. Replace the FFC of the CR encoder.
  7. Replace the CR unit.
  8. Replace the MAIN board.

• Code: 1124
• Description: CR reversing error
• Causes: Drive time of the CR motor exceeding the predetermined time was detected.
  • Firmware becomes out of control.
• Remedy: Replace the MAIN board.

• Code: 1125
• Description: CR home position detection error
• Causes: When the power is ON, the pump cap unit does not operate and the lock of the CR unit cannot be released. Thus, the CR home position cannot be detected.
  • False detection of the home due to paper jam or any other obstacle
  • Misreading of the CR scale
  • The CR lock is damaged.
• Remedy: 1. Is there any paper jammed inside the printer?
  2. Does the CR scale have any scratches or dirt?
  3. Check the reading status of the CR encoder with the Service Program.
  4. Does the CR lock function normally? (Check manually whether the pump unit functions or not.)
  1. Replace the pump cap unit.
  2. Replace the CR scale.
  3. Replace the CR encoder.

• Code: 1126
• Description: CR lock release error
• Causes: The lock of the CR unit cannot be released.
  • Pump unit failure
  • The CR lock is damaged.
• Remedy: 1. Check manually whether the pump unit functions.
  2. Is the CR unit stopped at the home position?
  3. Are there any foreign materials around the pump unit?
  1. Replace the pump cap unit.
  2. Replace the CR scale.

• Code: 1135
• Description: CR encoder test error
• Causes: The output of the CR encoder does not change even though the CR motor is commanded to rotate.
  • CR encoder failure (cable failure)
  • CR motor failure (cable failure)
  • Large CR unit load
• Remedy: Are there any problems, such as the FFC is damaged or disconnected, in the connection below?
  • CR encoder to SUB board (CN1)
  1. Replace the CR motor.
  2. Replace the driven pulley.
  3. Replace the CR timing belt.
  4. Replace the FFC of the CR encoder.
  5. Replace the CR unit.
  6. Replace the MAIN board.

• Code: 1222
• Description: PF drive timeover error
• Causes: Drive time of the PF motor exceeding the predetermined value was detected.
  • Firmware becomes out of control.
• Remedy: Replace the MAIN board.
