39 Chapter 2: Basic Operation
Points to Keep in Mind When Switching the Power On and Off
Do not switch off the main power while the sub power is switched on. The print heads may be left uncapped (that is, the printing
carriage may remain over the platen). If the machine is allow to stand to with the print heads uncapped for a prolonged period,
the print heads may become irreversibly clogged.
Before switching off the main power, be sure to hold down the [POWER] key for one second or longer to switch off the sub
power.
If the printing carriage stops while over the platen, press the [POWER] key to reset the power. The printing carriage moves and
the print heads are capped.
If the printing carriage does not move even when you reset the power using the [POWER] key, refer to "7-1 What to Do If" and
see "What to Do When the Print Head Carriage Does Not Move."
2-2 Switching the Power On and Off
Switching On the Power
Leave the main power switch turned on, and use the
[POWER] key to switch the power on and off in day-to-
day use.
