Description: Option LCF tray-up motor abnormality: The Option LCF tray-up motor does not run normally or the Option LCF tray does not move normally. (Feeding of any other drawer than the Option LCF is possible.)
Remedy: Is the tray motor driving? (Perform the output check in the test mode: 03-271) ↓ → NO . 1) Check if the connector on the LCF tray motor is not disconnected. 2) Check if the connectors J851 on the LCF board are not disconnected. 3) Check if the connector of the tray-up sensor is not disconnected. 4) Check if the actuator reaches the sensor. 5) Replace the LCF board. 6) Replace the LGC board. YES Is the tray-up sensor working? (Perform the input check in the test mode: 03-[FAX] OFF/[5]/[E] ↓ → NO . 1) Check if the connector of the tray-up sensor is not disconnected. 2) Check if the connectors J851 on the LCF board are not disconnected. 3) Check if the actuator reaches the sensor. 4) Check if the connector pins are not disconnected and the harness is not open circuited. 5) Replace the LCF board. 6) Replace the LGC board. YES 1) Check if the tray lifting mechanism has no abnormality. 2) Replace the LCF board. 3) Replace the LGC board.
Code: C260
Description: Peak detection error: Lighting of the exposure lamp (white reference) is not detected when the power is turned ON.
Remedy: Does the exposure lamp light? (Perform the output check in the test mode: 03-267) ↓ → YES → 1) Check if the connectors on the CCD and SLG boards are disconnected. 2) Check if the shading correction plate is detached or dirty. 3) Check if the conductor pattern on the CCD board is short circuited or open circuited. 4) Check if the conductor pattern on the SLG board is short circuited or open circuited. 5) Replace the lens unit. 6) Replace the SLG board. NO 1) Check if the connectors of the exposure lamp and inverter are disconnected. 2) Check the SLG board if the connector pin CN1 is disconnected and the harness is short circuited or open circuited. 3) Check if the conductor pattern on the SLG board is short circuited or open circuited. 4) Replace the SLG board. 5) Replace the inverter. 6) Replace the exposure lamp.
Code: C270
Description: Carriage home position sensor not turning OFF within a specified period of time: The carriages do not shift from their home position within a specified period of time.
Remedy: Are the carriages slightly moved to the feeding direction? Are the carriages staying at a position other than home position? ll → YES → 1) Check if the conductor pattern on the SLG board is short circuited or open circuited. 2) Replace the SLG board. NO 1) Check if the connector pin is disconnected and the harness is short circuited or open circuited. 2) Check if the conductor pattern on the SLG board is short circuited or open circuited. 3) Replace the SLG board.
Code: C280
Description: Carriage home position sensor not turning ON within a specified period of time: The carriages do not reach their home position within a specified period of time.
Remedy: Do the carriages make a big noise after they arrive at the home position? ↓ → YES → The carriage home position sensor is not turned ON. 1) Check if the connector of the sensor is disconnected. 2) Replace the carriage home position sensor. 3) Check if the conductor pattern on the SLG board is short circuited or open circuited. 4) Replace the SLG board. NO The carriages are stopped at the home position and do not move. 1) Check if the connector pins are disconnected and the harnesses are short circuited or open circuited. 2) Check if the conductor pattern on the SLG board is short circuited or open circuited. 3) Replace the SLG board.
Code: C360
Description: Wire cleaner drive motor abnormality: The wire cleaner drive motor does not run normally or the charger wire cleaner does not move normally.
Remedy: (1) Check if the main charger is not disconnected. (2) Check if the wire cleaner drive motor is driving. (3) Is the wire cleaner position detection switch working? (4) Replace the LGC board.
Code: C370
Description: Transfer belt cam motor abnormality: The transfer belt cam motor does not run normally when the power is turned ON or the copying is started.
Remedy: (1) Is the transport belt unit working normally? (there is no extraneous material or toner clod). (2) Check if the connector of the transfer belt cam motor is not disconnected. (3) Check if the connector CN335 on the LGC board is disconnected. (4) Check if the fuse on the LVPS has blown. (5) Check if the transfer belt release detection sensor and transfer belt contact detection sensor is working properly. (6) Replace the transfer belt cam motor. (7) Replace the LGC board.
