NIB crash

Turn the printer off (using the power switch at the back of the printer), wait 15 seconds and turn the printer on. If the error continues, call HP for technical support to troubleshoot the problem.

A Parallel Port error has occurred. Nothing is wrong with the printer as the error is caused by the PC’s parallel port.

HP recommends printing via the network card because the transmission time via the parallel port is very slow, which may be causing the error.

If using the network card is not possible or acceptable, it is recommended that the parallel port setting in the PC BIOS be set to ECP mode (contact the PC vendor for instructions). This configuration should eliminate or decrease the frequency of this error.

The 040000 class of Error Codes can also be network or Jetdirect related. Follow the additional steps below if the problem is not Parallel related or changes to configuration do not solve the issue.

1. Turn the printer off and unplug the network cable.
2. Turn the printer on.
3. When the printer comes ready, print a demo from the the printer’s front panel. If the error does not come up at that time, it is most likely related to the network. Plug the network cable in and print a test page from the workstation.
4. If the printer does not come ready, turn the printer off, remove the Jetdirect card, and turn the printer back on.
5. If the printer comes to ready, replace the Jetdirect card.
6. If the error returns only when the printer is plugged into the network, the issue is most likely a network issue.
   Check the network settings (IP address, etc.) on the printer, workstation, and server (if applicable). If everything looks ok, perform a cold reset on the Jetdirect card (through the front panel). Reconfigure the IP address.
7. If the error still exists, connect the printer to the workstation using a peer-to-peer connection, using the printer’s IP address, and bypassing the print server. If the error goes away, the issue is with the print server. In this case, the customer should contact his/her IT support.

Explanation

How to Fix :

Drop Detect failure.

Turn the printer off (using the power switch at the back of the printer), wait 15 seconds and turn the printer on. If the error continues, call HP for technical support to troubleshoot the problem.

The Drop Detector is not calibrated or the calibration settings have been lost.

Press ENTER on the printer’s front panel to continue (the printer will still function, although the Drop Detector is not calibrated). If the error persists, call HP for technical support to troubleshoot the problem.

An Error has occurred in the Printhead Drop Detection. This error code appears when the printer detects that the same areas of nozzles do not work in different printheads.

1. Turn the printer off, using the main power switch located on the back of the printer.
2. After 10-15 seconds, turn the main power switch on.
3. If no error appears, attempt to verify printer functionality.
4. If the error re-appears, continue with the remaining steps.
5. Attempt to manually recover the printheads:
   1. Scroll to the Printhead menu icon (icon on the lower right of the front panel display) and press Enter.
   2. Using the Arrow keys, scroll to Recover Printheads and press Enter.
   3. Re-cover the offending printhead(s).
6. Attempt to verify printer functionality.
7. If the error re-appears or problems persist, contact HP support.

Print Mask could not be generated. The mask generation algorithm could not generate the print mask. Possible causes are memory corruption, print mode definition incompatible with mask restrictions (if using an external RIP).

Turn the printer off, wait 15 seconds and turn the printer back on (the error should disappear). If an External RIP is being used, verify printer functionality by using the HP driver (HP-GL/2 or PostScript®). If no errors occur using the HP driver, the RIP is causing the error (contact RIP vendor). Check the status of all printheads and replace any that display the message “XX21 Replace”. If the error persists, call HP for technical support to troubleshoot the problem.

The primer is not calibrated or the calibration settings have been lost.

Turn the printer off (using the power switch at the back of the printer), wait 15 seconds and turn the printer on. If the error continues, call HP for technical support to troubleshoot the problem.
