Turn the printer on and off

To turn on the printer, ensure that the residual current circuit breakers are in the up position and the

power switch at the rear of the printer is turned on. If the printer does not start automatically, press the

Power

button on the front panel.

You can leave the printer on without wasting energy. Leaving it on improves response time. When the

printer has not been used for a certain period of time, it saves power by going into sleep mode. Any

interaction with the printer returns it to active mode, and it can resume printing immediately.

If you want to turn the printer on or off, the normal and recommended method is to use the

Power

button on the front panel.

When you turn off the printer this way, the printheads are automatically stored with the printhead

cleaning cartridge, which prevents them from drying out.

However, if you plan to leave the printer turned off for a long period of time, you are recommended to

turn it off using the

Power

button, and then also turn off the power switch at the rear.
