Hallo There i have this :  Error Code 0X00759C98 HW WATCHDOG C 

I unplugged the power but  the problem was not solved ...

I have already unplugged the printer from the wall outlet and the USB cord from the PC, taken out the ink cartridges and reset the whole thing, but still not working.

@Tsapte70 Lets start with power reset as per HP standards, here's how we recommend doing it:

• Turn the printer on, if it is not already on.
• Wait until the printer is idle and silent before you continue.
• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
  • NOTE: 
  • HP recommends connecting the printer power cord directly to the wall outlet.
• Reconnect the power cord to the rear of the printer.
• Turn on the printer, if it does not automatically turn on.
• Wait until the printer is idle and silent before you proceed.

If the issue persists, please upgrade the printer firmware:
