Unfortunately HP Technicians are the only ones who can help, this is a EPROM error code and there are no tools available to the public.

    I found this also, It might help

    To initialize NVRAM
    1. Remove any installed accessories (for example, a stapler/stacker).
    2. Turn the printer power off.
    3. Hold down the DOWN ARROW ( ) button, and then turn the printer power on. Continue
    holding down the DOWN ARROW ( ) button until all three printer control panel lights flash
    once and then remain on. This might take up to 10 seconds.
    4. Press the UP ARROW ( ) button.
    5. Press the PAUSE/RESUME button. The display should show SKIP DISK LOAD.
    6. Press the UP ARROW ( ) button until NVRAM INIT is highlighted.
    7. Press the SELECT ( ) button. The printer initializes NVRAM and then continues its
    power-on sequence.

Service Error 49.4CF2


Usual solution is to update the firmware of the printer. The quickest solution is to use a different printer driver. So if using PCL, try Post Script (or the other way around).

Hp Laser Jet 4350dtn network printer is showing Service Error 49.4C02 how do I fix


Does it occur on any print job or one in particular. If it happens with one job, that job has a problem. It isn't the printer.
If it is all printing go the www.hp.com. then go to "support and drivers". Then select your printer, select your operating system, select firmware. Upgrade your firmware. Make sure that you read the instructions and DO NOT touch the printer while it is upgrading.
If the firmware upgrade completes and the errors continue, you will need to replace the formatter.

49.FF95 Service error in HP Laserjet 4350dtn printer. Pls help me what is the exact error.


It's a critical firmware error. Try printing another job. If that one works, something is corrupt with the first job. Still failing remove any extra DIMMs from the formatter. Don't remove the one in slot J1. That's the firmware DIMM. try to print. If it works, reinstall the DIMM and try again. Failure = bad DIMM. You may want to try a firmware upgrade. If everything keeps failing you'll have to replace the formatter.

HP Laser jet 4350 dtn printer gets 59.40 error. I


Print Cartridge Motor Error.
Try removing then re-installing the cartridge. If that does not work then you will need to try a different toner cartridge as the toner cartridge is "locked up". These are the most common solutions. If none of these work then you have a cartridge drive problem and will need to contact a service center.

Replaced fuser unit on HP 4350dtn and now get a 50.5 error.


Hello,

The 50.5 error indicates "wrong fuser installed" on a 4350DTN printer the correct fuser is RM1-1082, it will not work with RM1-0101 even if the 0101 fits the printer. Remove the fuser and look for a small label giving the part number and check it. If you need to get a fuser let me know, we have them in stock.

Service error 49.4C02


General 49 errors are formatter related. It can be caused by software, bad memory. See if you can isolate if its one app. maybe even one document that has a problem. If all cause swap the dimms except the lowest 2 which are the firmware. And try. Next Print config. Check firmware version and call HP to see if there is a revision upgrade. Last and most expensive is replace the formatter.

HP Laserjet 4350dtn Print Quality poor


Most likely the fuser has lost part of the teflon from the heat roller. Having said that, the first step in any print quality issues is to change the toner cartridge. good luck!
