• Code: 900.xx
• Description: RIP Software Error. The 900 error may indicate a communication problem (bad cable, network connection, and so on), software issue, or a hardware problem with the controller board/INA. The communication and software aspects should be checked first. Determine if the problem is constant or intermittent.
• Remedy: 1 Reset the ITU electrical disconnect. Turn the printer off. Check the ITU release lever for correct operation. The ITU release lever is the black lever located on the left upper side frame above the ITU opening and can be seen by opening and lowering the MPF assembly. When locked, the lever should be at the 6 o'clock position. When unlocked, it should be in a 3 o'clock position. Undue pressure is not required to operate the lever. Turn the printer off, insert the ITU, move the lever to the 6 o'clock position, and turn the printer back on. Does the 900 error display? Go to step 2 Problem resolved. 2 Disconnect the printer from any external connections. Turn the power off and remove any parallel, USB, or network connections. Turn the printer on. Does the 900 error display? Go to step 4 Go to step 3 3 Run the internal test pages. Print one of the internal test pages from the Utilities Menu. If the printer works correctly while disconnected, have the user or their network administrator verify that there are no jobs in the queue which may be causing the error. Does the error remain? Inform the user or network administrator of the issue. Go to step 4 4 Turn the printer off. Remove any options from the system board, such as additional memory, hard disk drives, or option cards. Does the 900 error persist when the printer is turned on? Go to step 5 Determine which option is causing the 900 error. 5 Restore factory defaults from the Configuration Menu. Warning: When factory defaults or restored, all menu items are returned to the factory default values except: • Display Language. • All settings in the Parallel Menu, Serial Menu, Network Menu, and USB Menu. All downloaded resources (fonts, macros, and symbol sets) in printer memory (RAM) are deleted. (Resources residing in flash memory or on the hard disk are unaffected.) Record the secondary error codes. With the 900 Service RIP Error displayed, press Menu ( ) and together Record the complete list by scrolling with the arrows ( or ). The code may be a very long string of characters and numbers, but is needed for analysis. Contact your next level of support. Problem resolved

• Code: 902.xx...907.xx
• Description: Engine Software
• Remedy: General Engine Software Errors 902 through 907 indicate an unrecoverable engine software error. The system board may cause this type of error. Turn the printer off and on to try and clear the error code. If this does not fix the problem after several attempts, contact your next level of support before replacing the system board.

• Code: 908.xx
• Description: Engine Hardware Failure
• Remedy: General Engine Hardware Error 908 indicates an unrecoverable engine electronic hardware error. The system board may cause this type of error. Turn the printer off and on to try and clear the error code. If this does not fix the problem after several attempts, contact your next level of support before replacing the system board.

• Code: 925.02
• Description: Fan Stalled Fuser fan
• Remedy: 1 Turn the power off, manually spin the fan, and check that it rotates freely. Does the fan rotate freely? Go to step 2 Replace the fuser fan. See “Fuser fan removal”. 2 Check the fuser fan cable connection to the system board JM1 for correct installation. Is the cable installed correctly? Go to step 3 Install the cable correctly. 3 Disconnect the fuser fan from JM1 on the system board, and check the voltages on JM1. Are the voltages correct? Replace the fuser fan. See “Fuser fan removal”. Replace the system board. See “System board removal”.

• Code: 926.01
• Description: Fan Stalled VTB fan
• Remedy: 1 Turn the power off, manually spin the fan, and check that it rotates freely. Does the fan rotate freely? Go to step 2 Replace the VTB fan. See “Vacuum transport belt (VTB) fan removal”. 2 Check the VTB fan cable connection to the system board JY1 for correct installation. Is the cable installed correctly? Go to step 3 Install the cable correctly. 3 Disconnect the VTB fan from JY1 on the system board, and check the voltages on JY1. Are the voltages correct? Replace the VTB fan. See “Vacuum transport belt (VTB) fan removal”. Replace the system board. See “System board removal”.

• Code: 927.03
• Description: Fan Stalled RIP Fan
• Remedy: 1 Turn the power off, manually spin the fan, and check that it rotates freely. Does the fan rotate freely? Go to step 2 Replace the RIP fan. See “RIP fan removal”. 2 Check the RIP fan cable connection to the system board JR1 for correct installation. Is the cable installed correctly? Go to step 3 Install the cable correctly. 3 Disconnect the RIP fan from JR1 on the system board, and check the voltages on JR1. Are the voltages correct? Replace the RIP fan. See “RIP fan removal”.
