Symptom Cause/Remedy
The printer is not on. Is the power switch or power switch off?
Switch the main power on. Then, switch the power on by pressing the <|> side of the
power switch.
Is the power cord firmly plugged into the power outlet?
Switch the power and the main power off, and then disconnect and reconnect the power
cord from the power outlet and the printer. Next, switch the main power and the power
on.
Is the printer plugged into a power outlet that supplies the proper voltage?

control panel to exit Energy Saver mode.
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?

cannot be removed without dismantling the printer, contact our Customer Support
Center or your dealer.

the printer.
On the control panel, set the Sleep mode trigger time to more than 60 minutes, and let

causes the condensation to evaporate.
