49.5001 error on LaserJet 4100

Posted on 2006-03-30

Previously I had my HP LaserJet 4100 connected to a Windows 2000 SP4 machine. It was time to replace the old computer and so I brought in a new Dell Dimension 5150 with XP SP2 on it. This computer did not come with any parallel port cards on it so I purchased a PCI-Parallel port card for my printer (on LPT1). I connected the printer to the new comp and has been printing fine for 2 days. I cam ein this morning and the error on the printer was : "49.5001" error.

I researched this and it seems to be a firmware problem??? Please advise how to fix this problem.

    Accepted Solution

    Per the HP Service Manual the followiing is provided:

    Control Panel Message:

    49.XX Printer Error
    alternates with Cycle Power To Continue


    A firmware error occured.

    Recommended action:

    1.  Press "Cancel Job" to clear the print job from the printer memory.
    2.  Turn the printer off and then turn the printer on.
    3.  Try printing a job from a different software application.  If the job prints, go back to the first application and tryu printing a different file.  (If the message only appears with a certain software application or print job, contact the software vendor for assistance.)
    4.  If the message persists with different software applications and print jobs, disconnect all cables to the printer that connect it to the network or printer.
    5.  Turn the printer off.
    6.  Remove all memory DIMMs or third-party DIMMs from the printer.  (Do not remove the firmware DIMM in the lowest DIMM slot.)
    7.  Remove all EIO devices from the printer.
    8.  Turn the printer on.
    9.  If the error no longer exists, install each DIMM and EIO device one at a time, making sure to turn the printer off and back on as you install each device.
    10.  Replace a DIMM or EIO device if you determine that it causes the error.
    11. Remember to reconnect all cables that connect the printer to the network or computer.
    12.  If the error persists, replace the firmware DIMM.
    13.  Replace the formatter.

    Hope this Helps!!!

    If you have another printer to swap parts with I'd do that before buying anything to definitively identify a bad part.  :-)

    We get this error semi regular an ALL our HP network printers. It is a bad data error. Just do an off/on reset and maybe delete and resubmit the print job currently printing.
