Power Save Mode and Sleep Mode

Two-phase power conservation enables you to
save on power consumed by the printer.

 Power Save Mode

When your printer is not used for a certain
period of time, it automatically enters the power
save mode to reduce the power consumption.

You can enter the power save mode manually
by pressing the <POWER SAVE> button on the
operator panel.

The <POWER SAVE> button lights up green
while in this mode.

Memo

● By factory default, the time interval before entering the
power save mode is set to 1 minute. For how to change
the time that elapses before the printer enters the power
save mode, refer to “Setting the Time that Elapses Before

Entering the Power Save Mode” P.76.

 When the Printer is Not Used for a

Long Time

When the printer is not used for a long time due
to consecutive holidays or when on vacation, or
when changing or attaching parts in repair or
maintenance, unplug the AC cord.

Memo

● The printer will not be functionally impaired even if left
unplugged for a long time (more than 4 weeks).

 Sleep Mode

Your printer goes from the power save mode to
the sleep mode after a set period of time.

In the sleep mode, the status of your printer is
almost the same as when it is turned off.

The <POWER SAVE> button blinks while in the
sleep mode.

Note

● The printer does not enter the sleep mode if an error
occurs.

Memo

● By factory default, the time interval before entering the
sleep mode is set to 15 minutes. For how to change the
time that elapses before the printer enters the sleep
mode, refer to “Setting the Time that Elapses Before

Entering the Sleep Mode” P.77.

Reference
