“Currently printing at low speed due to low voltage power supply.”

Printing has slowed down because the power supply voltage is low.

This is not a malfunction. You can continue printing although the printing speed is low.

“Internal cooling fan is active.”

Large print runs will cause the machine's interior to heat up, triggering the cooling fan.

The fan will emit noise, but this is normal and the machine will be operable while the fan is running.

The amount of paper that can be printed and the total operation time until the fan starts running depends on the temperature of the location at which the machine is installed.

“Printing was stopped due to the power supply being low voltage. Turn the main power switch off then on.”

Printing has stopped because the power supply voltage is low.

Turn off the power, and then turn it on again.

“Self checking...”

The machine is performing image adjustment operations.

The machine may perform periodic maintenance during operations. The frequency and duration of maintenance depends on the humidity, temperature, and printing factors such as number of prints, paper size, and paper type. Wait for the machine to resume operation.
