When you try to print to you HP Printer it fails to print and you see the error error 49.4C02 on the lcd screen of the printer.
This is normally down to a corrupt firmware on your printer. Don’t panic you MAY be able to fix this by overwriting the firmware / BIOS of the printer.
We need to re flash this printer so go to the link below and download the flash utility.
It is a single file. Make sure the green ready button is on the printer.
Once downloaded simply double click it, it will show you all the printers installed, select the faulty printer and click flash.
Reset the printer and this should remove the error 49.4C02
