The manual suggested that resending the BIOS update would clear it. Once they finished asking me to do all the things I had already tried, they sent out an engineer. After 3 weeks of undoubtedly expensive engineer call-outs, HP sent a new printer instead.These things cost about £800 to buy, so sending out replacements is not undertaken lightly.Other causes include poor quality parallel cables, poor connections, or homegrown applications.On rareoccasions, the formatter is at fault, which is usually indicated by a 79 Service Error.1.There are several possible reasons why a firmware upgrade might fail: We have walked dozens of technicians through this procedure, when they have called our technical service department, and have been very successful. If for some reason this does not clear the error, then you will need to replace the formatter board.
I understand that this can be caused by faulty cables or corrupt data being sent to it. A critical firmware error has occurred that caused the processor on the formatter to abort operation.
This is the tale of how I started down the long, dark, road of hatred towards HP, and why I think they are largely incompetent at what they do.
If you’ve read more than five posts on this blog you may have noticed that already.
This package contains the files needed for installing the HP Laser Jet P4000 Series Printer Firmware.
If it has been installed, updating (overwrite-installing) may fix problems, add new functions, or expand existing ones.
