Resetting the HP Printer
Switch ON your HP Printer.
Wait until your printer gets to settle down and completes all its internal initializing functions. Once it is ready, it will go silent.
Disconnect the power cord from your printer which is present at the back of the printer while the printer is still in ON mode.
Now unplug the power cable from the main power outlet.
Wait for more than 60 seconds and plug back the power cable in the wall outlet and also connect the power cable of your printer.
Now, switch ON your HP Printer.
