HP forum: Scan link failed to wired PC

I have an HP Officejet Pro L7780 All-in-One Printer (Model No CBO39A - serial Number MY841850QQ) Bought new 13/11/08.

It is hard wired in to my WIN7 ultimate 64bit PC as is my wife's PC Win7 ultimate 32 bit. Also 2 laptops use the device by WiFi. A maximum of only two devices operate at once.

All functions have worked perfectly after professional installation and setup ever since.

THis is a purely domestic i.e.light useage situation.


Early in January 2011 the scan function to the WIN7 64 bit PC failed.

Both I and my professional contractors (who incidentally have the same model in their office) have carried out all the usual tests and steps, culminating in repeated un-installation and re-installation of the device, un-installation of the HP software suite (downloaded each time) and re-installation, booting and rebooting of the PC.

It still refuses to scan when requested, from the PC HP control centre to the PC.


The professional contractors are beaten. I have found to my horror that HP do not seem interested in helping other than for a fee. This for which when bought was a pricey item not a cheapo and after only a couple of years of very light use.

The extended error information the setup produces is

8,[(1,0,-2147221164)]

Am I doomed to throw out this otherwise excellent piece of expensive kit or does anyone out there have a clue please as to how to solve my problem
