C4400 stuck in scan mode

[duncan_a]

My printer now seems to be permanently in scan/copy mode.

I haver tried full power-down and the very basic reset by means of Cancel+Power buttons but did not find more than language and region options.

It is operating via WiFi by means of using the USB port on my ADSL Router and has functioned in this configuration for more than a year without a problem.

I have seen mention of HP printers being 'hacked' but I don't know if that is a possible factor or not.

I tend to rely on printing things as, following a stroke, I have difficulty processing information off the screen and find it far easier (if very costly) to work from a physical printed page.

Thanks for any help.

Hi! @duncan_a, Welcome to HP forums.

I understand your printer is stuck in scan mode.

Don't worry I'd like to help you out.

Did you make any changes to your printer?

Please try the steps recommended below.

In some cases, removing the ink cartridges and resetting the printer can clear the error message.
Turn on the printer.
Wait until the printer is idle and silent before you continue.
Disconnect the USB cable from the rear of the printer. If your printer has a network or wireless connection, leave it connected.
Remove the ink cartridges from the printer.
With the printer turned on, disconnect the power cord from the rear of the printer and from the wall outlet or power strip.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.
   NOTE:
HP recommends connecting the printer power cord directly to a wall outlet.
Reconnect the power cord to the rear of the printer.
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.
If you receive a prompt to print a calibration page, do so.
If you disconnected the USB cable, reconnect it to the rear of the printer.
Try to print.

If the issue still persists try performing a semi full reset on your printer and check if it helps.

Since the steps to perform semi full reset is confidential, I will send you the steps in a private message. Please watch your inbox for more information.

Let me know if this helps!

Have a great day ahead! 🙂
