• Code: SC231
• Description: FGATE OFF error The FGATE signal did not turn OFF within 9 sec. after the writing procesended.
• Causes: • GAVD defective • Image processing ASIC defective • IPU, controller board not connected correctly or defective • Harness between IPU and LDB defective
• Remedy: • Turn the power off/on. • Replace the IPU board. • Replace the controller board.

• Code: SC240
• Description: LD error: During LD lighting /During initialization of P-MAC
• Causes: • LD degradation (LD broken, shift of output characteristics etc.) • The interface harness damaged or not connected correctly. • LD driver defective
• Remedy: • Cycle the main power off/on • Replace the LD unit • Replace the harness • Replace the IPU board

• Code: SC270
• Description: GAVD communication error When machine starts or cancels the energy saving
• Causes: • GAVD defective • CPU defective • BCU defective
• Remedy: • Cycle the main power off/on • Replace the IPU board • Replace the controller board • Replace the BCU board • Set the FCC between BCU - IPU

• Code: SC302
• Description: Charge level output error The PWM output level was detected higher than 50% after 10 consecutive samplings.
• Causes: • high voltage power supply board defective • Harness of the high voltage power supply board (power pack) is loose, broken. • PCU connection loose or broken
• Remedy: • Cycle the main power off/on • Replace the high voltage power supply board • Replace the harness of the power pack. • Replace the harness of the PCU. • Replace the PCU.

• Code: SC355
• Description: ID sensor error • One of the following conditions occurred when the ID sensor pattern was calibrated during printing: Vsp > 2.5V, Vsg < 2.5V, Vsp = 0V, Vsg = 0V • The following conditions occurred simultaneously when the ID sensor pattern was calibrated during printing: Vsg = 5V, PWM = 0 (LED current drop) • Error occurred during automatic adjustment of Vsg: Vsg output did not attain 4V, even with PWM = 1023 (maximum current for LED) Vsg output was greater than 4V, even with PWM=1 (no current for the LED)
• Causes: • ID sensor dirty or defective • ID sensor harness disconnected, or connector damaged • BCU defective • High voltage power supply board (power pack) defective • Scanning system or image creation system malfunction
• Remedy: • Replace the ID sensor harness. • Replace the ID sensor. • Replace the harness of the high voltage power supply board (power pack). • Replace the harness of the BCU. • Replace the BCU.

• Code: SC389
• Description: TD sensor error 1 TD sensor output was less than 0.5V, or more than 0.5V 10 times in succession. If the fax unit is installed, this SC is issued immediately. If the fax unit is not installed, this SC is issued after the prescribed number of copies has printed.
• Causes: • TD sensor abnormal • Poor connection of the TD sensor harness
• Remedy: • Replace the TD sensor. • Replace the harness of the TD sensor.

• Code: SC390
• Description: TD sensor error 2 The TD sensor outputs less than 0.5V or more than 4.0V 10 times consecutively during copying. Note: If the fax option is installed, this SC is issued immediately. If the fax option is not installed, this SC is issued after the prescribed number of pages is copied.
• Causes: • TD sensor abnormal • Poor connection of the TD sensor harness
• Remedy: • Replace the TD sensor. • Replace the harness of the TD sensor.

• Code: SC391
