• Code: 33.02.01
• Display: 33.02.01 Used board/disk installed
• Description: Used board disk installed. An encrypted board or disk with existing data previously locked to a different printer has replaced the original. If you continue, data is permanently lost.
• Remedy: 1. Reinstall the used board or disk back into its original printer. 2. To save the data on the board or disk, turn the printer off. replace the board or disk with another board or disk. 3. To delete the data on the board or disk and continue, touch the OK button.

• Code: 41.02.00
• Display: 41.02.00 Error
• Description: A beam detected misprint error occurred.
• Remedy: 1. To clear the error message, touch OK.2. If the error persists, turn the printer off, and then on again.3. If the error returns, check the wire harness from the laser/scanners to the DC controller.

• Code: 41.03.FZ
• Display: 41.03.FZ Unknown Misprint Error
• Description: This is a general misprint error. Either media is loaded off-center with the side guides in the tray or a media width sensor failure occurred from an unknown tray
• Remedy: 1. Reload the tray, verifying that the guides in the tray are flush with the loaded media in the tray.2. Try the print job again. Watch the mechanism to see if it is functioning correctly. If the linkage is broken, replace the paper tray.3. If the error persists, print a Configuration Page and note the paper size for the tray in question. • If the size is not reported correctly, run the tray size sensor test in the Diagnostic menu. • If the tray size sensors test as GOOD, replace the paper tray. • If the tray size sensors test as BAD, check the cable connections between the tray size sensor and the DC Controller. If the cable connections are plugged in correctly and the cables are not compromised, replace the correct component that contains the tray size sensing switches.

• Code: 41.03.YZ
• Display: 41.03.YZ Unexpected size in tray <X>
• Description: The printer detected a different paper size than expected.
• Remedy: 1. Touch OK to use another tray. 2. Print a configuration page to verify the size and type to which the trays are set. 3. Make sure that the tray is loaded with the correct paper size and that the sliding paper guides are correctly adjusted to the correct paper size. 4. Verify that the error is not occurring as a result of an unexpected paper size trigger caused by a multipage feed. 5. Verify that the Toner cartridge and the transfer roller are seated properly. 6. Use the Tray/Bin manual sensor test to verify that the cassette media switch is correctly functioning. 7. Check paper path sensors SR6 and SR9 for proper operation and that they do not stick at all. Replace any damaged sensor or assembly. 8. Check paper width sensors SR13 and SR14 for proper operation and that they do not stick at all. Replace any damaged sensor or assembly. 9. Reconnect the connectors for the media sensor, intermediate-transfer belt, and the DC controller PCA. NOTE: • SR6 Top Sensor connects to DCC on J118. • SR9 Fuser Delivery sensor connects to Fuser PCA on J2603 then to interconnect J50 then to DCC on J116. • SR13 and SR14 Media Width sensors connect to DCC on J118. 10. Test registration assembly motor and clutch. If not function properly replace the registration assembly. If the error persists, replace the lifter assembly.

• Code: 41.04.YZ
• Display: 41.04.YZ Printer Error
• Description: An unknown misprint error occurred on the printer. Y = Type, Z = Tray
• Remedy: 1. Touch OK to clear the error.2. If error does not clear, turn the printer off, and then on again.3. Swap out or re-seat each toner cartridge to test it.4. Check the toner cartridges before replacing any other parts (HP original?, connectors, etc.).5. Re-seat the connections to the laser/scanner and the DC controller.6. If the error persists, replace the affected laser/scanner.7. Replace the DC controller.

• Code: 41.05.YZ
• Display: 41.05.YZ Unexpected type in tray <X>
• Description: The printer can detect the type of paper in the paper path, and it adjusts the print mode accordingly. The printer uses two types of media sensors: • Reflection: Detects the glossiness of the paper. • Transmission: Detects the thickness of the paper. Tray X is loaded with a media type (transparencies, envelopes, etc.) that is different than what they tray is configured to use. Y = Expected type, Z = Detected type
• Remedy: 1. Load the tray with the size and type of paper indicated, or use another tray if available.2. If this message displays and the tray is loaded with the correct paper type, check the print driver settings to make sure they match the tray type settings.3. Check all application and printer settings to make sure that the Type setting is correct.

• Code: 41.XX.YZ
• Display: 41.XX.YZ Error To continue, touch “OK”
• Description: This section covers all other errors of the form 41.XX.YZ not covered in the previous sections. A printer error has occurred. XX = error type Y = fuser mode Z = input tray
• Remedy: 1. To clear the message, touch the OK button.2. If the message displays again, turn the printer off, and then on again.3. If the error persists, replace the DC Controller PCA.
