• Code: 84
• Description: Replace Photoconductor
• Remedy: This message displays when the photoconductor is at the end of life. The photoconductor must be replaced.

• Code: 88
• Description: Toner Low
• Remedy: This message displays when toner low occurs and the toner low alarm is activated. Press or Start to clear the message and continue printing. Press Stop to cancel the job being processed.

• Code: 900
• Description: Service RIP software
• Remedy: Server firmware problem. Turn off the MFP for one minute. If that does not fix the problem, contact the next level of support.

• Code: 900
• Description: Service (No Modem)
• Remedy: Modem Controller card Ensure the phone line is properly connected to the top RJ-11 jack of the modem and phone jack on the wall. Ensure the modem cable is properly connected to the J69 on the modem card and J69 on the controller card. Check the connectors on both cards for damage. Check pin 1 on J69 for +5V. Check pins 3 and 4 for +3.3V. Pins 2, 9, 14, 18, 22, and 27 should be ground. If voltages are present, replace the modem card. If the voltages are not present, replace the controller card.

• Code: 902
• Description: General engine software failure
• Remedy: An unrecoverable engine software error. Reset the MFP (POR). If the problem continues, replace the controller card. A 902.33 error will occur if Tray 2 is set as the default, and Tray2 is improperly, or not attached to the MFP.

• Code: 914
• Description: DC Pick Motor
• Remedy: Verify motor is plugged into controller card correctly. Also, check the load condition. Replace the drawer 2 assembly.

• Code: 917
• Description: Transfer roll
• Remedy: The most likely cause is a faulty HVPS. It may also indicate a problem in the transfer roll area. Transfer roll Check transfer roll area for debris, and clean as necessary. Verify continuity between the spring below the left side bearing and the transfer roll shaft. Verify continuity in the spring and the cable connection on the LVPS/HVPS. Inspect the roll for signs of wear or damage, and replace if necessary.

• Code: 920
• Description: Fuser Error Indicates that the fuser is below temperature when printing.
• Remedy: Lamp cable LVPS/HVPS Fuser Unplug the MFP and disconnect the fuser lamp cable plug from the LVPS/HVPS board connector CN102. Check for continuity across the fuser lamp by checking across the connector pins. • If there is continuity, go to Step 1: Continuity. • If there is no continuity, go to Step 2: No continuity. Step 1: Continuity Turn the MFP on with only the fuser power disconnected. Measure the voltage at connector CN102 on the LVPS/HVPS. It should match the line voltage. If line voltage is not present, see “LVPS/HVPS service check” for more information. Make sure the fuser thermistor is correctly connected to the controller board. If the problem persists, disconnect the thermistor cable at J15 and check for less than +5 V dc on pin 1. Pin 2 should be ground. If line voltage is incorrect on pin 1, see “Controller card service check” for more information. Step 2: No continuity Check the lamp cable for continuity. • If correct, replace the fuser. • If incorrect, replace the lamp cable. Disconnect the thermistor cable from J15 on the controller card. Measure the resistance across the ends of the thermistor cable. See “Controller card” for more information. Replace the fuser assembly if the resistance is lower than 1K ohm or shorted. Note: Resistance measures approximately 240K ohms when cool and 1.4K ohms hot.
