• Code: 9600
• Description: When printing with the tray designation set to AUTO, the MP paper empty sensor, T1 paper feed sensor and T2 paper feed sensor all detected that there was no paper set in the MP tray, paper tray 1 and paper tray 2.
• Causes: 1 Main PCB failure
• Remedy: Replace the main PCB ASSY.

• Code: 9700
• Description: When printing from paper tray 1, a paper size not supported for paper tray 1 was specified from the driver.
• Causes: 1 Main PCB failure
• Remedy: Replace the main PCB ASSY.

• Code: 9800
• Description: When printing from paper tray 2, a paper size not supported for paper tray 2 was specified from the driver.
• Causes: 1 Main PCB failure
• Remedy: Replace the main PCB ASSY.

• Code: 9900
• Description: A paper size not supported for duplex printing was specified from the driver.
• Causes: 1 Main PCB failure
• Remedy: Replace the main PCB ASSY.

• Code: 9A00
• Description: There is no paper set in the MP tray while feeding from the MP tray is fixed.
• Causes: 1 MP paper empty actuator 1 or 2 caught in some sections of the machine. 2 Failure of MP paper empty actuator 1 or 2. 3 MP paper empty sensor failure. 4 High-voltage power supply PCB failure. 5 Main PCB failure.
• Remedy: 1 MP paper empty actuator 1 or 2 caught in some sections of the machine Reattach the MP paper empty actuator 1 or 2. 2 Failure of MP paper empty actuator 1 or 2 Replace the MP paper empty actuator 1 or 2. 3 MP paper empty sensor failure Refer to "1.3.10 Check sensor operation (function code: 32)" in Chapter 5 to check the sensor operation. If the sensor operation is faulty, replace the MP paper empty sensor PCB ASSY. 4 High-voltage power supply PCB failure Replace the high-voltage power supply PCB ASSY. 5 Main PCB failure Replace the main PCB ASSY.

• Code: 9F01
• Description: The T1 paper feed sensor detected that paper has run out during faxing or printing a list or report.
• Causes: 1 High-voltage power supply PCB failure. 2 T1 paper feed sensor failure. 3 Main PCB failure.
• Remedy: 1 High-voltage power supply PCB failure Replace the high-voltage power supply PCB ASSY. 2 T1 paper feed sensor failure Replace the T1 paper feed sensor PCB ASSY. 3 Main PCB failure Replace the main PCB ASSY.

• Code: A000
• Description: Image processing cannot be completed correctly because the number of pixels required for image processing is insufficient in the scanned data for the second side of the document.
• Causes: 1 Incorrect correction data for second side CIS. 2 Second side CIS unit failure. 3 Main PCB failure.
• Remedy: 1 Incorrect correction data for second side CIS Execute function code 55. 2 Second side CIS unit failure Replace the second side CIS unit. 3 Main PCB failure Replace the main PCB ASSY.

• Code: A100
• Description: The front cover sensor detected that the front cover was open.
• Causes: 1 Connection failure of the front cover sensor harness. 2 Connection failure of the relay front harness. 3 Front cover sensor attachment failure. 4 Broken rib (inside the front cover) where the front cover sensor is pressed. 5 Front cover sensor failure. 6 Relay front PCB failure. 7 Main PCB failure.
• Remedy: 1 Connection failure of the front cover sensor harness Check the connection of the front cover sensor harness, and reconnect it if necessary. 2 Connection failure of the relay front harness Check the connection of the relay front harness, and reconnect it if necessary. 3 Front cover sensor attachment failure Reattach the front cover sensor. 4 Broken rib (inside the front cover) where the front cover sensor is pressed Replace the front cover. 5 Front cover sensor failure Refer to "1.3.10 Check sensor operation (function code: 32)" in Chapter 5 to check the sensor operation. If the sensor operation is faulty, replace the relay front PCB ASSY. 6 Relay front PCB failure Replace the relay front PCB ASSY. 7 Main PCB failure Replace the main PCB ASSY.
