Error 2200 for my Dell all-in-one 926 printer

When I moved to a new place, my dell printer started to give an error message “Error 2200” every it starts. I tried to google around and found the solution on this page:

Basically the steps are:

  1. Switched off the printer.
  2. Unplugged the power.
  3. Press the power button for 15 seconds.
  4. plugged in back the power.
  5. Turn on.
