• Code: 355-00
• Description: ID sensor error If one of the SC codes from 350 to 354 happens when the SP5-995-001 is set to “0” (default), SC355 is issued as the logging SC. This error is not displayed on the panel.
• Causes: • ID sensor defective • ID sensor harness damaged • ID sensor not connected correctly • MPU defective • Laser unit defective • Imaging density fault • HVPS board defective • ID sensor dirt
• Remedy: • Replace the ID sensor. • Reconnect the ID sensor connector.

• Code: 360-01
• Description: TD sensor calibration error The error of the TD sensor calibration is determined if the TD sensor calibration is not out of the target range described below. The TD sensor calibration error is detected three times consecutively, this SC is issued. • Upper threshold (SP2-992-001) • Lower threshold (SP2-992-002)
• Causes: • TD sensor defective • TD sensor harness not connected correctly or damaged • Not initial developer
• Remedy: • Replace the harness of the TD sensor. • Insert the connector of the TD sensor. • Replace the development unit.

• Code: 361-01
• Description: TD sensor output upper limit error (K) TD sensor output: The Vt (SP2-220-004) output continuously exceeds the upper limit threshold value (SP2-992-001) for the time of the upper limit threshold (SP2-992-003).
• Causes: TD sensor is not connected correctly.
• Remedy: • Check if the TD sensor connector is connected. • Check the harness of the TD sensor (disconnected, etc.). • Replace the development unit if some error is detected.

• Code: 362-01
• Description: TD sensor output lower limit error (K) TD sensor output: The Vt (SP2-220-004) output is continuously below the lower limit threshold value (SP2-992-002) for the time of the lower limit threshold (SP2-992-004).
• Causes: TD sensor is not connected correctly.
• Remedy: • Check if the TD sensor connector is connected. • Check the harness of the TD sensor (disconnected, etc.). • Replace the development unit if some error is detected.

• Code: 392-00
• Description: Initial developer setting error • A read error for the ID sensor pattern at the initial developer setting is detected. • If the Vsp output is more than 2.5 V, the machine detects that there is no developer, and displays SC.
• Causes: • ID sensor defective • The OPC drum does not rotate. • The development roller does not rotate.
• Remedy: • Replace the ID sensor. • Replace the developer. • Replace the PCDU.

• Code: 440-00
• Description: Image transfer current error The machine detects "1" (error) 10 times consecutively when monitoring the output error signal every 20 msec (excluding in Sleep mode or with the front door open).
• Causes: Right door not closed correctly PCDU out of position HVPS board defective HVPS board harness defective
• Remedy: • Close the right door correctly. • Reinstall the PCDU correctly or replace the PCDU. • Replace the HVPS board. • Replace the harness of the HVPS board.

• Code: 502-01
• Description: 2nd tray (option) error (lift error) The tray lift sensor does not detect the tray bottom plate or stack of paper for 10 seconds after the machine start to initialize all units. * If the machine detects an error three times consecutively, this SC is issued.
• Causes: • Tray lift motor error or harness disconnected • Tray lift sensor error or harness disconnected • Each harness damaged • Main board defective • Foreign matter, such as paper scrap, is caught between the tray and tray lift motor or in the tray. • Paper set fault • Bottom plate defective • Paper feed roller missing • Tray lift sensor feeler defective
• Remedy: • Reload the paper. • Remove the foreign matter. • Replace the tray lift motor. • Reconnect the connector. • Replace the harness. • Replace the tray lift sensor. • Replace the main board. • Replace the tray. • Replace the paper feed roller. • Replace the tray lift sensor feeler. • Replace the bottom plate.

• Code: 502-02
• Description: 2nd tray (option) error (lowering error) The tray lift sensor does not turn off for 1,000 msec. after the tray bottom plate has started to lower when the upper limit and paper load are simultaneously detected at the power-on or tray installation. * If the machine detects an error five times consecutively, this SC is issued.
• Causes: • Tray lift motor error or harness disconnected • Tray lift sensor error or harness disconnected • Each harness damaged • Main board defective • Foreign matter, such as paper scrap, is caught between the tray and tray lift motor or in the tray. • Paper set fault • Bottom plate defective • Paper feed roller missing • Tray lift sensor feeler defective
• Remedy: • Reload the paper. • Remove the foreign matter. • Replace the tray lift motor. • Reconnect the connector. • Replace the harness. • Replace the tray lift sensor. • Replace the main board. • Replace the paper feed roller. • Replace the tray lift sensor feeler • Replace the tray bottom plate. • Replace the tray.
