Hp colour laserjet 4600dn, in this printer coming 51.2c error

The printer counter needs to be reset by going into menu and finding resets. Then toggle down until you come across Transfer Kit & press ok.

You have a failed JetDirect network card (look on back where the network cable plugs in) usually a grey or white slot card with 2 thumb screws (ex: 610n). If this is add-in card, you can buy a replacement and reinstall it. If the network port is built onto the printers fomatter (main board), then you need an authorized HP repair center to replace and set the serial number through service mode.

Power down Machine and restart. If error comes back , you need to order a fusing unit or maintenance kit depending on the pages printed. To get the counts for the last maintenance kit press check mark and scroll to information ,check mark then print configuration page check mark.

That indicates that the printer has a network card problem. You can try rebooting/resetting which can clear it but usually means a trip to the hp repair shop.

No guarantee this will fix your problem, but the last time I experienced this problem it ended up being one of the toner cartridges. I replace her refurb. toners to OEM brand.

From Woody Friesen:
Did the printer have a rough ride? HP's service manual suggests this to be a laser error on the yellow laser scanner, though these printers usually withstand shipping without any problems. Just for grins, if you can get the printer to get to READY again, run the printer through a complete calibration (from the control panel: Configure Device/Print Quality/Calibrate Now). The DC controller circuit board is also a possibility, but given the error code popped up almost as soon as you plugged the machine in suggests the yellow scanner has suffered some sort of mechanical damage from the trip. If the calibrate routine doesn't remedy the problem and you want to be sure, you could do the major disassembly required and swap the yellow scanner with the scanner for another color in the printer and if the error code changes to 51.2M (magenta), 51.2C (cyan) or 51.2K (black) (the code will reflect which scanner you exchanged with the one in the yellow position) you'll have confirmed the scanner is the problem, or if no change, then the DC controller is next in the chain.

Make sure the settings are properly set within the program and printer.

It is a fan failure

try re installing the original software for the printer. sometimes hp drivers get corrupted by either use or anti virus. this normally should fix the problem If it does not please come back

The problem is usually caused by printing a PDF file with fonts/page size/ page formating errors which will cause the printer to display the 49.3048 error. The only way to use the printer is to POR or recycle the power and delete the print job from the server or spooling device and cancel it on the printer before the offending command is issued to the printer again. You can try updating the firmware to the latest version 46.140.5 from the HP website. MIke L.
