Not sure how touch screens operate. Other HP users had same problem but no real fix found on the net. Icons on one half of the screen still work but those on right side don't. Sounds like a part electrical/mechanical failure of the touch screen imo. Been a decent printer scanner till now. Still works as a printer from PC but doesn't want to scan.

anyone come across anything similar? cheers

Which model is it? Its not always a hardware fault its sometimes the touch screen needs recalibrating.

Hewlett Packard photosmart 5515

Can't find details of the software for that one. I guess you have tried the usual firmware update and factory reset tricks.

Some of the printers have a touchscreen calibrate in the desktop support software.

A bodge that works on some hp printers is press and hold the screen on the right side then touch the corresponding position on the left side.

Presumably you can still scan using the desktop software.
