Description: LCF end fence motor abnormality: The LCF end fence motor is not rotating or the LCF end fence is not moving normally. (the case that paper can be fed from any drawer except the LCF)
Causes: LCF end fence motor LCF board LGC board LCF end fence home position sensor LCF end fence stop position sensor
Remedy: 1 Is the LCF end fence motor working? (Perform the output check: 03-207) Yes 2 No • Check if the connector of the LCF end fence motor is disconnected. • Check if any of the connectors CN100, CN101 and CN103 on the LCF board is disconnected. • Check if the connector CN349 on the LGC board is disconnected. • Check if the connector pins are disconnected or the harnesses are open circuited. • Check if the conductor patterns on the LCF board and LGC board are short circuited or open circuited. 2 Are the LCF end fence home/stop position sensors working? (Perform the input check: 03-[ALL]OFF/[0]/[A], /[0]/ [B]) Yes 3 No • Check if the connectors of the sensors are disconnected. • Check if either of the connectors CN100 or CN107 on the LCF board is disconnected. • Check if the connector CN349 on the LGC board is disconnected. • Check if the slit reaches the sensors. • Check if the connector pins are disconnected or the harnesses are open circuited. • Check if the conductor patterns on the LCF board and LGC board are short circuited or open circuited. 3 LGC board • Check if the conductor pattern on the LGC board is short circuited or open circuited.

Description: LCF transport motor abnormality: The LCF transport motor is not rotating normally (when paper can be fed from any drawer except the LCF).
Causes: LCF transport motor LCF board LGC board
Remedy: 1 Is the LCF transport motor working? (Perform the output check: 03-122/172) Yes 2 No • Check if the connector CN112 of the LCF transport motor is disconnected. • Check if the connector CN102 on the LCF board is disconnected. • Check if the signal line connector CN100 on the LCF board is disconnected. • Check if the power line connector CN101 on the LCF board is disconnected. • Check if the connector CN349 on the LGC board is disconnected. • Check if the connector pins are disconnected or the harnesses are open circuited. • Check if the connector pins are disconnected or the harnesses are open circuited. 2 LCF transport motor LGC board • Check if the connector pins are disconnected or the harnesses are open circuited. • Check if the conductor patterns on the LCF transport motor board, LCF board and LGC board are short circuited or open circuited. • Check if the PLL lock signal CN102-3 pin output from the LCF board is always “L” level. • Check if the voltage supplied to the microcomputer input terminal IC103-17 pin is always “L” level.
Code: C260
Description: Peak detection error: Lighting of the exposure lamp (white reference) is not detected when power is turned ON.
Causes: Lens unit SLG board Inverter Exposure lamp
Remedy: 1 Does the exposure lamp light? (Perform the output check: 03-267) Yes 2 No 3 2 CCD board SLG board • Check if the connectors on the CCD and SLG boards are disconnected. • Check if the shading correction plate is dirty. • Check if the conductor pattern on the CCD board is short circuited or open circuited. • Check if the conductor pattern on the SLG board is short circuited or open circuited. 3 Exposure lamp Inverter SLG board • Check if the connectors of the exposure lamp and inverter are disconnected. • Check the SLG board if the connector pin CN21 is disconnected or the harness is short circuited or open circuited. • Check if the conductor pattern on the SLG board is short circuited or open circuited.
Code: C270
Description: (1) Carriage home position sensor not turning OFF within a specified period of time: The carriage does not shift from its home position in a specified time. (2) Downloading firmware with an incorrect model. If the error occurs, the exposure lamp lights twice at the same time.
Causes: SLG board
Remedy: 1 Are the carriages slightly moved to the feeding direction?/Are the carriages staying at a position other than home position? Yes Check if the circuits of the SLG board are abnormal. No 2 2 SLG board • Check if the connector pin is disconnected or the harness is short circuited or open circuited. • Check if the conductor pattern on the SLG board is short circuited or open circuited. • If the model of the firmware downloaded is incorrect, a C270 error (exposure lamp blinks twice) occurs. If the exposure lamp blinks twice, download the correct ROM.
Code: C280
Description: Carriage home position sensor not going ON within a specified time
Causes: Home position sensor SLG board
Remedy: 1 Do the carriages make a big noise after they arrive at the home position? Yes 2 No 3 2 Home position sensor SLG board The carriage home position sensor is not turned ON. • Check if the connector of the sensor is disconnected. • Check if the circuits of the SLG board are abnormal. 3 SLG board The carriages are stopped at the home position and do not move. • Check if the connector pins are disconnected or the harnesses are short circuited or open circuited. • Check if the conductor pattern on the SLG board is short circuited or open circuited.
Code: C290
Description: Scanner fuse blowout: 24V power for the scanning system is not supplied at the scanner warming-up after power-ON.
Causes: Fuse in the scanning system SLG board
Remedy: 1 Power supply unit Check if any fuse in the scanning system is blown out. 2 SLG board Check if the conductor pattern on the SLG board is short circuited or open circuited. Check if the 24V output and the grounding wire are normal.
