Wiring Data

• 24VDC Supply Interruption by the Interlock Switch when the Rear Cover, Top Cover, OCT
Rear Cover, or the 2000 Sheet Feeder Rear Cover is open, the Interlock Switch is deactuated
to open the 24 VDC supply circuit between the LVPS and the Print Engine Controller PWB. As
the result, 24 VDC supply to the Print Engine Controller PWB, and hence Motors, Clutches,
and Solenoids are stopped. However, the Fans are always supplied with 24 VDC without being
interrupted by the deactuation of the Interlock Switch.

/FAN LOW ON(L) 24V

Fan speed switching signal that switches the speed of rotation of
the Fuser Fan and LVPS Fan between High and Low: Low speed,
High: High speed

/FAN HIGH ON(L) 24V

Fan speed switching signal that switches the speed of rotation of
the Fuser Fan and LVPS Fan between High and Low: High
speed, High: Low speed

Description

FAN ON

ages, 24V for High speed and 15V for Low speed

/FAN ALM (TTL)

Fan monitor signal. Goes Low when the rotation of the Fuser Fan or
LVPS Fan is abnormal
