e-STUDIO170F Circuit Description

7.3.6
Super Power Save Circuit
Fig.7-24
This machine is equipped with power save functions to control the power consumption by cutting off the
power of the circuits not used while in the standby state. For the power save functions, there are the
printer power save function, which cuts off only the supply of power to the fuser and the super power
save function, which cuts off the supply of power to any circuits other than the minimum required.
For the printer power save function, refer to
P.7-28 "7.3.4 Fuser Control Circuit" in this chapter.
Consisting of the Sub-CPU (IC56) as the central component, the super power save circuit cuts off the
supply of +24V and ±12V, and +5V to other than the super power save circuit when the facsimile
machine has been in the standby state for a fixed time (auto power save mode) or the SUPER
ENERGY SAVER key has been pressed (manual power save mode), thereby greatly reducing the
power consumption.
