Question about HP LaserJet 4345mfp Printer
49.4 C18 error
49.XXXX is a fatal catch-all error. Could be firmware problem, network, print job. If the error occurs when you try to print, clear the print queue. If the error occurs when the printer is just sitting idle, reseat the formatter. Try powering on without the network cable attached. If it still happens replace the formatter. Could be a corrupt print job being sent to printer. Print something else.

a 49.xxxx error on an HP means that there is an issue with one or more hard disks. you can try to re-initialise the hard disk(s) by rebooting the printer while holding the green button. when the three leds are lit, release the green button, and navigate using the numerical buttons until you see "initialise hard disks" on the display of the printer. confirm by pressing the green button again. if all goes well, your printer will take two minutes longer than usual to boot. if you still get the same error afterwards, you need to replace the disk.

The 49 code is related to one of three things on this unit.
1. You accidentally used a refurbished toner instead of one directly from the manufacturer which tends to cost a bit more. The certified one from the dealer is known to clear this error code instantly.
2. Your internal memory cash will need to be reset
3.You have internal hardware failure which can not be repaired by the user and must be sent to the manufacturer.
