I recently loaded this printer onto my computer. We have had the printer for a long time but I don't use it very frequently. Recently I upgraded my computer and OS to Windows 10. I have been trying to install the driver and get the printer working for two days. At first it seemed as if everything was going well, and at that point I tried to set up Wireless printing. This was unsuccessful and I gave up. I had planned on setting up USB (which is fine as I do not use this printer often). But ever since, the printer has been stuck with power on and the status bar on. I have removed and reloaded the C4780 driver several times. I have unplugged the power and the usb cords from the printer several times, even over night without success. I cannot find any information for a hard reset on the printer. Wondering what to do.

Thank you for reaching out to the HP Support community!
- Are you able to remove the ink cartridges from the printer?
Let's try to perform a Power Reset on the printer. This may fix the issue.
- Make sure this printer is plugged into a direct wall, not a surge protector.
- Turn the printer on.
- Wait until the printer is idle and silent before you continue.
- Remove all of your ink cartridges from the printer and close the door.
- With the printer turned on, disconnect the power cord from the rear of the printer.
- Unplug the power cord from the wall outlet.
- Disconnect the USB cable
- Wait at least 60 seconds.
- Plug the power cord back into the wall outlet.
- Reconnect the power cord to the rear of the printer.
- Reconnect the USB cable
- Turn on the printer, if it does not automatically turn on. The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
- Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
- Reinsert the ink cartridges, and then close the ink cartridge access door.
- Check if you can print/copy
- If the issue persists, try connecting the printer to a different wall outlet and check.
