The printer is not on. Is power switched off?
Switch the power on by pressing the <|> side of the power switch.
Is the power cord firmly plugged into the power outlet?

power outlet and the printer. Next, switch the printer on.

If this does not remedy the problem, check if the power cord is firmly plugged into the
power outlet, and reboot the printer.
If the problem still persists, there may be a problem with the printer. Contact our
Customer Support Center or your dealer.
The printer makes odd noise. Is the printer installed on a level surface?
Install the printer on a level and sturdy surface.

Is there a foreign object inside the printer?

dismantling the printer, contact our Customer Support Center or your dealer.
Condensation has formed in
the printer.

the condensation to evaporate.
