A shift is made only in response to the passage of time (auto low-power shift time) selected
in user mode.
The power used by the machine is reduced to enable the machine to remain in a state that
satisfies the standards under Energy Star.The power supplied to the reader unit will remain
ON except the +24V power, which the reader unit uses to generate internal power. (All
operations remain at rest.)
The printer unit keeps the temperature of the fixing unit to a specific level (190 deg C) which
is lower than when the machine is in normal operating mode.
A shift is made in response to the passage of time (auto sleep shift time) specified in user
mode or in response to a press on the control panel software power switch.
In sleep mode 1 (relatively higher power consumption), the fixing assembly is totally
deprived of power. The DC controller PCB, however, remains supplied with power.
In sleep mode 2 (relatively lower power consumption), on the other hand, the printer unit
(including the fixing assembly) remains OFF; the main controller PCB is supplied with all-
night power as indicated in the table:
