device busy error message

@AMZU87, Welcome to HP Support Community!


Going through your post, it looks like a scanner failure issue with your printer. This happens when the printer gets insufficient power to the scanner or when there is a mechanical issue with the printer scanner mechanism. Try the steps mentioned below to try and fix the issue:

  • Remove the toner cartridges from the printer.
  • With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
  • Remove USB cable, if present.
  • Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
  • Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
  • Turn on the printer and wait till the warm-up period finishes and the printer is idle.

If the issue persists, please reach out to the HP Support in your region regarding the service options for your printer.


Hope this helps!
