Description: Abnormal external LCF tray-up motor (Paper can be fed from cassettes other than the external LCF)
Remedy: Is the tray motor driving? (Perform the output check in the test mode: 03-271) 1. Check if the connector J815 on the LCF tray motor is not disconnected. 2. Check if the connectors J801~804 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. Check if the power (24V) is supplied to 1pin and 2pin of J803. If not, check if the door switch is turned ON and the harness of it is not open-circuited. 6. Replace the LCF board. 7. Replace the LGC board. Is the tray-up sensor working? (Perform the input check in the test mode: 03-[ENERGY SAVER] OFF/[1]/[C] 1. Check if the connector of the tray-up sensor is not disconnected. 2. Check if the connectors J801~804 on the LCF board are not disconnected. 3. Check if the actuator reaches the sensor. 4. Check if the coppector pins are not disconnected and the harness is not open-circuited. 5. Replace the LCF board. 6. Replace the LGC board. 1. Check if the tray lifting mechanism has no abnormality. 2. Replace the LCF board. 3. Replace the LGC board.
Code: C26
Description: Peak detection error
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 dirty. 3. Check if the conductor pattern on the CCD board is short- or open-circuited. 4. Check if the conductor pattern on the SLG board is short- 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 J9 is disconnected and the harness is short- or opencircuited. 3. Check if the conductor pattern on the SLG board is short- or open-circuited. 4. Replace the SLG board. 5. Replace the inverter. 6. Replace the exposure lamp.
Code: C27
Description: Carriage home position sensor not going OFF within a fixed time
Remedy: Are the carriages slightly moved to the feeding direction?/Are the carriages staying at a position other than home position? YES Check if the circuit of the SLG board is abnormal. NO 1. Check if the connector pin is disconnected and the harness is short- or open-circuited. 2. Check if the conductor pattern on the SLG board is short- or open-circuited. 3. Replace the SLG board.
Code: C28
Description: Carriage home position sensor not going ON within a fixed 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. Check if the circuit of the SLG board is abnormal. 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- or open-circuited. 2. Check if the conductor pattern on the SLG board is short- or open-circuited. 3. Replace the SLG board.
Code: C36
Description: Abnormal main charger wire cleaner drive motor
Remedy: (1) Check if the main charger is not disconnected. (2) Check if the wire cleaner drive motor is driving. (3) Replace the LGC board.
