My HP Photosmart C4640 All-in-One is "short-circuiting". The touch-pad menu screen is constantly changing from menu to menu--it scans, then copies, then says "insert memory card", then gives an error code, on and on. I have tried uninstalling the software and drivers, then reinstalling, only to get an error on reinstall. I have Windows 7. Is my printer pooched? It is only 6 years old.

Hello @ila1,
Welcome to the HP Support Forums! 🙂 I understand your HP Photosmart C4640 is in an error state. You have tried uninstalling and reinstalling with no success.
Let's go ahead and try a Hard Reset:
1. Unplug all cables and memory cards from the printer. Unplug the power cord, directly from the back of the printer while the printer is still turned on.
2. Unplug the other end of the cord from the power source.
3. If there is a power module on the power cord, disconnect one end and reconnect it.
4. After 60 seconds, plug the cord directly into a wall outlet (not a surge protector or battery backup as they can cause the printer to lose basic functionality over time).
5. Plug the power cord into the back of the printer.
6. The printer should automatically power back up. If it doesn't, turn it on with the power button.
7. Try making a photocopy (if your printer is an all-in-on printer) before connecting any other cables to the printer.
8. Connect any other needed cables to the printer.
If you are still unable to use the printer, please call our technical support at www.hp.com/contacthp/ as it may be the hardware. If you live outside the US/Canada Region, please click the link below to get the support number for your region. http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html
I hope this helps!

I am sorry the hard reset did not work but I shall try again. It will still print but only if I get the print command in before it starts to go crazy changing from menu to menu.
Thanks for your effort. I shall contact hp.com/contacthp now.
