Description: BLACK PC Drum sensor malfunction - The output from the Black PC Drive Main and Sub Sensors remains unchanged for a continuous period of 1,000 ms while the Main Motor is turning stably and the Lock signal is active (LOW-0).
Causes: • Transport Drive Assy • Mechanical Control Board (PWB-M) • Harness
Remedy: 1 Check if the Detect Light Shield Plate has damages and is properly installed, and correct as necessary. - - 2 Check the Transport Drive Assy connector for proper connection and correct as necessary. - - 3 Check the PWB-M connector for proper connection and correct as necessary. - - 4 Change the cable that connects Transport Drive Assy and PWB-M. - - 5 Change Transport Drive Assy - - 6 Change PWB-M
Code: E630
Description: IDC Sensor (front) failure - All outputs of Sensor photo-receiver section from the detection point (unprinted surface on the Image Transfer Belt) are 0.5 V or less, or 4.3 V or more at output checking during IDC Sensor adjustment. - All outputs of Sensor photo-receiver section from the detection point (unprinted surface on the Image Transfer Belt) are 1.9 V or less, or 4.4 V or more at density setting during IDC Sensor adjustment. - The output of Sensor photo-receiver section from the detection point (toner pattern on the Image Transfer Belt) is 1.0 V or less after the adjustment.
Causes: IDC Sensor
Remedy: 1 Check that the IDC Sensor is properly installed and correct as necessary. - - 2 Check if the IDC sensor is dirty and correct as necessary. - - 3 Check the IDC Sensor connector for proper connection and correct as necessary. - - 4 Check the PWB-M connector for proper connection and correct as necessary. - - 5 Change the cable that connects IDC Sensor and PWB-M. - - 6 Change the IDC Sensor.
Code: E631
Description: IDC Sensor (back) failure - All outputs of Sensor photo-receiver section from the detection point (unprinted surface on the Image Transfer Belt) are 0.5 V or less, or 4.3 V or more at output checking during IDC Sensor adjustment. - All outputs of Sensor photo-receiver section from the detection point (unprinted surface on the Image Transfer Belt) are 1.9 V or less, or 4.4 V or more at density setting during IDC Sensor adjustment. - The output of Sensor photo-receiver section from the detection point (toner pattern on the Image Transfer Belt) is 1.0 V or less after the adjustment.
Causes: IDC Sensor
Remedy: 1 Check that the IDC Sensor is properly installed and correct as necessary. - - 2 Check if the IDC sensor is dirty and correct as necessary. - - 3 Check the IDC Sensor connector for proper connection and correct as necessary. - - 4 Check the PWB-M connector for proper connection and correct as necessary. - - 5 Change the cable that connects IDC Sensor and PWB-M. - - 6 Change the IDC Sensor.
Code: E640
Description: Color Shift Test Pattern failure - The number of points detected in the main scan direction is more or less than the specified value during main scan direction registration correction. - The number of points detected in the sub scan direction is more or less than the specified value during sub scan direction registration correction.
Causes: • Transfer Belt Unit • IDC Sensor • Photoconductor Unit • PH Unit
Remedy: 1 Check if Transfer Belt has damages and correct as necessary. - - 2 Check that the IDC Sensor is properly installed and correct as necessary. - - 3 Check if the IDC sensor is dirty and correct as necessary. - - 4 Check the IDC Sensor connector for proper connection and correct as necessary. - - 5 Check the PWB-M connector for proper connection and correct as necessary. - - 6 Change the cable that connects IDC Sensor and PWB-M. 7 Change IDC Sensor. 8 Change Photoconductor Unit. 9 Change PH Unit.
Code: E641
Description: Color Shift Adjust failure - The color shift amount is greater than the specified range during main scan direction registration correction. - The color shift amount is greater than the specified range during sub scan direction registration correction. - The skew correction amount is greater than the specified value.
Causes: • PH Unit (displacement) • Transfer Belt Unit
Remedy: 1 Execute the correction of skew. - - 2 Check if Transfer Belt has damages and correct as necessary.
Code: E701
Description: MP tray Rise Descent Error - The Bypass Lift-Up Sensor is not blocked even when the Vertical Transport Motor has turned for a given number of pulses after the sequence to move the Paper Lifting Plate from the standby position to the feed position was started. - The Bypass Lift-Up Sensor is not unblocked even when the Vertical Transport Motor has turned for a given number of pulses after the sequence to move the Paper Lifting Plate from the feed position to the standby position was started.
Causes: • MP tray Lift-up Sensor (PC14) • Vertical Transport Motor (M2-PC) • Control Board (PWB-Z-PC)
Remedy: 1 Check the M2-PC connector for proper connection and correct as necessary. - - 2 Check the connector of M2-PC for proper drive coupling and correct as necessary. - - 3 PC14 I/O check, Sensor check PWB-M CNTRY1-10 (ON) C-10 4 M2-PC operation check PWB-Z PJ5Z PC-5~8 Q-22 5 Change PWB-Z-PC.
