• Code: 13.B2.DD
• Display: 13.B2.DD Jam in top cover area
• Description: Paper stay jam at top/registration sensor from the duplexer. This jam occurs when the paper does not reach the TOP sensor (SR9) within the designated amount of time from the Duplexer.
• Remedy: 1. Open the top cover, remove any jammed paper, and then close the top cover. NOTE: Do not remove the toner cartridge. 2. Make sure that the duplexer is seated properly and check for obstructions in the paper path. 3. Use the Components tests to activate the duplex feed motor (listen for the motor to rotate). If the motor is not properly functioning, replace the duplexer. 4. Use the Manual sensor tests to toggle the duplexer sensors (SR1DU, SR2DU). If the sensors are not properly functioning, replace the duplexer. 5. Make sure that the registration assembly shutter is properly functioning. Replace the registration assembly if necessary. 6. Check the toner cartridge for damage. Replace the cartridge if necessary. 7. Use the Manual sensor tests to toggle the TOP sensor (SR9). If the sensor is not properly functioning, replace the high-voltage power supply. 8. Inspect the connector (J62) on the DC controller PCA, and connector (J901) on the high-voltage power supply. 9. Use the Components tests to activate the drum motor (listen for the motor to rotate). If the motor is not properly functioning, replace the main drive assembly.

• Code: 13.B2.DX
• Display: 13.B2.DX Jam in top cover area
• Description: Paper delay jam at top/registration sensor- This jam occurs when the leading edge of the media does not reach the TOP sensor (SR9) within the designated amount of time from Tray 4, 5, or 6. X indicates the source tray - 4 = Tray 4 - 5 = Tray 5 - 6 = Tray 6
• Remedy: 1. Open the top cover, and then remove any jammed paper. IMPORTANT: Do not remove the toner cartridge. Make sure that you remove any jammed paper from the top cover area before proceeding to avoid tearing partially picked paper. Close the top cover. 2. Check for obstructions in the paper path from the source tray. 3. Check the pickup, feed, and separation rollers from the source tray. Replace the rollers if they are worn or defective. 4. Make sure that the registration assembly shutter is properly functioning. Replace the registration assembly if necessary. 5. Use the Components tests to activate the pickup motor and the pickup solenoid/clutch (listen for the motor/solenoid to rotate/move) for the source tray. If the motor or solenoid are not properly functioning, replace the motor or solenoid. 6. Use the Manual sensor tests to toggle the TOP sensor (SR9). If the sensor is not properly functioning, replace the high-voltage power supply. 7. Inspect the connector (J62) on the DC controller PCA, and connector (J901) on the high-voltage power supply. 8. Use the Components tests to activate the drum motor (listen for the motor to rotate). If the motor is not properly functioning, replace the main drive assembly.

• Code: 13.B2.FF
• Display: 13.B2.FF Jam in top cover area
• Description: TOP sensor (SR9) residual jam. This jam occurs when paper exists at any of the paper path jam sensors when the product power is turned on or after a jam re-evaluation.
• Remedy: 1. Open the top cover, and then remove the toner cartridge. Remove any jammed paper, and then close the top cover. 2. Use the Manual sensor tests to toggle the TOP sensor (SR9). If the sensor is not properly functioning, replace the high-voltage power supply. 3. Inspect the connector (J62) on the DC controller PCA, and connector (J901) on the high-voltage power supply.

• Code: 13.B4.FF
• Display: 13.B4.FF Jam in top cover area
• Description: Loop sensor (SR6) residual jam. This jam occurs when paper exists at any of the paper path jam sensors when the product power is turned on or after a jam re-evaluation.
• Remedy: 1. Open the top cover, and then remove the toner cartridge. Remove any jammed paper, and then close the top cover. 2. Inspect the connector (J62) on the DC controller PCA, and connector (J901) on the high-voltage power supply. 3. Use the Manual sensor tests to toggle the loop sensor (SR6). If the sensor or lever are not properly functioning, replace the high-voltage power supply.

• Code: 13.B9.AX
• Display: 13.B9.AX Fuser area jam
• Description: Fuser or duplexer stay jam- This jam occurs when the engine detects a paper stay jam at the fuser output sensor (SR12)- Most likely there is an accordion jam in the fuser exit path. X indicates the fuser mode - 2 = Normal - 3 = Light media 1 - 3 = Light media 2 - 4 = Heavy media 1 - 5 = Heavy media 2 - B = Transparency - D = Envelope 1 - D = Envelope 2
• Remedy: 1. Open the left door, remove any jammed paper, and then close the left door. 2. Check the paper path and rollers at the fuser and at the paper delivery assembly for a blockage or damage. Replace the fuser or paper delivery assembly if necessary. 3. Use the Manual sensor tests to toggle the fuser output sensor (SR12) and the paper delivery output sensor (SR3). If a sensor is not properly functioning, replace the appropriate assembly. 4. Use the Components tests to activate the fuser drive motor and duplex feed motor (listen for the motor to rotate). If the motor is not functioning properly, replace the fuser motor or duplexer.

• Code: 13.B9.CX
• Display: 13.B9.CX Fuser wrap jam
• Description: This jam occurs when the paper leaves the fuser output sensor (SR12) before a designated amount of time after the paper reached the fuser output sensor (the paper is wrapped around the fuser roller). X indicates the fuser mode - 2 = Normal - 3 = Light media 1 - 3 = Light media 2 - 4 = Heavy media 1 - 5 = Heavy media 2 - B = Transparency - D = Envelope 1 - D = Envelope 2
• Remedy: 1. Remove the duplexer (if installed). Remove the left door, and then remove the fuser. Remove any jammed paper from the fuser, and then reinstall the fuser. NOTE: Remove any other jammed paper from the fuser area. Reinstall the left door, and duplexer (if removed). Close the left door. 2. Perform a cleaning page procedure to clean the fuser rollers. 3. Use the Manual sensor tests to toggle the fuser output sensor (SR12). If the sensor is not properly functioning, replace the fuser. 4. If the error persist, the fuser pressure roller might be damaged. Replace the fuser.

• Code: 13.B9.DD
• Display: 13.B9.DD Fuser area jam (top cover)
• Description: This jam occurs when the leading edge of the page does not reach the fuser output sensor (SR12) in the designated amount of time.
• Remedy: 1. Open the left door to release fuser roller pressure. IMPORTANT: Do not attempt to remove the jammed paper. Open the top cover, and then remove the toner cartridge. Remove any jammed paper, and then reinstall the toner cartridge. Close the top cover and left door. 2. Check the paper path and rollers at the fuser and duplexer for damage. Replace the fuser or duplexer if necessary. 3. Use the Manual sensor tests to toggle the fuser output sensor (SR12). If the sensor is not properly functioning, replace the fuser. 4. Inspect the following connectors: - Fuser, J1 - Fuser motor, J1100 - DC controller, J6 and J47 - High-voltage power supply, J902 5. Use the Components tests to activate the duplex feed motor (listen for the motor to rotate). If the motor is not properly functioning, replace the duplexer.
