3. Pre-heat mode and sleep mode
operations
A. Operation timing
This machine has a pre-heat mode and a sleep mode to save the
power consumption when copying (printing) is not performed.
power consumption when copying (printing) is not performed.
The shift timing to the pre-heat mode and the sleep mode can be
set with the user program with the non-operating state as the start
point.
set with the user program with the non-operating state as the start
point.
The timing of the two modes can be separately set. It is possible to
shift from the normal mode directly to the sleep mode without pass-
ing through the pre-heat mode.
shift from the normal mode directly to the sleep mode without pass-
ing through the pre-heat mode.
(Pre-heat mode cancel conditions)
In the following cases, the pre-heat mode is canceled.
(Sleep mode cancel condition)
In the following cases, the sleep mode is canceled.
(Sleep mode shift timing extending condition)
When the non-operation of copying and printing continues and the
following case occurs within 10 min of entering the sleep mode, set
the sleep mode timer to 10 min again, and extend the shift timing to
the sleep mode.
following case occurs within 10 min of entering the sleep mode, set
the sleep mode timer to 10 min again, and extend the shift timing to
the sleep mode.
