1.4 Turning the Printer On/Off
1.4.1 Turning the printer on
With the printer plugged in to a power source, press the POWER button to turn on the
printer. When the printer turns on, it starts the initializing operation.
If a BJ cartridge is not installed, the
indicator blinks in green to indicate that the
printer is ready to have the BJ cartridge installed and the carriage will move to the
cartridge replacement position. If a BJ cartridge is already installed, the
indicator will
light in green to indicate that the printer is in standby status.
When the printer is turned on after more than 72 hours have passed since the last
head cleaning (the first head cleaning is performed 24 hours after a color BJ cartridge
is installed), it automatically carries out head cleaning. The
indicator blinks in green
while head cleaning is performed.
1.4.2 Turning the printer off
Press the POWER button to turn off the printer.
When the printer is turned off, it executes a power-off sequence operation to cap the
nozzles of the BJ cartridge for their protection and to prevent ink leakage. The
indicator blinks in green to indicate that the power-off sequence is under progress.
When the power-off sequence is complete, the indicator goes out. Make sure the
indicator is off first before unplugging the AC power cord.
Never turn off the printer by unplugging the AC power cord before
pressing the
POWER button . This will cause the printer to turn off before it
can cap the BJ cartridge and as a result the ink will leak out or dry out
and clog the nozzles.
If the AC power cord has been unplugged to turn off the printer, plug in the AC power
cord, press the
POWER button to turn on the printer, and then turn it off again.
If the POWER button is pressed while the head is being cleaned, the indicator continues
blinking in green until the head cleaning is completed. After cleaning is completed,
the BJ cartridge is capped and the printer turns off. Any error occurring after the
power-off sequence starts is ignored and the printer is turned off.
CAUTION
Figure 3-11 Caution! Do not unplug the AC power cord
without pressing the POWER button first
