2.2.1.3 PS Control Function
This power supply circuit enables to supply the voltage to the 5V, 3.3V and 42V lines
for about 30 seconds by using the secondary power supply even if the power is turned
off with the power switch on the operation panel. This procedure ensures the following
operation even if the printer's power switch is turned off while printing.
When the CR unit is not at the home position while the printer is printing, the
CR unit stops printing, then the power is shut down after returning to the
home position and finishing the locking action.
When the papers are stored in the printer mechanism in the condition supplied
by the ASF even if the printer is not printing, the paper is ejected and then the
power is shut down.
2.2.1.4 Power saving mode
The power supply circuit activates the power saving mode by the signal ESAVE from
the control circuit. The +42V line repeats rise/fall in the power saving mode.
