Power Supply Operations

Precautions When Operating the Power Supply

Always keep the main power switched on.
Never switch off the main power. When the main power is on, the automatic maintenance function is carried
out periodically. If the automatic maintenance is not carried out, the printer may malfunction. For example,
the print heads may be damaged.
2
Never switch off the main power or unplug the power cord suddenly while operation is
in progress.
Switching off the main power or unplugging the power cord suddenly while operation is in progress may
damage the print heads. Be sure to first switch off the sub power. If the main power is accidentally switched
off, immediately turn the main and sub power back on.

Sleep Mode (Power-saving Feature)

This machine is provided with a power-saving feature that switches to a low-power "sleep mode" when a
fixed interval passes with no operation. The factory default for the time after which the machine switches to
sleep mode is 30 minutes. When the machine is in sleep mode, the sub power switch flashes slowly. Using
the operation panel or sending printing data from the computer restores the machine to its normal mode.
This sleep mode setting can be changed. However, we recommend setting the activation time for sleep mode
to 30 minutes or less to reduce power consumption and prevent problems such as overheating.
