DATA
ACON_
AC power relay drive signal for fusing unit (Heater lamp) (Drive at LOW) Purpose is
protection against hung up.
DRIVE
ASTB_
Signal identification signal (Used to identify address/data line signals A0
∼
A7 to address
signal or data signal. Address signal at LOW
CONTROL
BSCON
Developing bias voltage control signal (When this voltage is increased, the developing bias
voltage is also increased.)
CONTROL (ANALOG)
CBSON_
Developing bias ON signal (Cyan) (Developing bias voltage is outputted at LOW)
CONTROL
CBSY_
Controller busy (ICU) signal
LOW when in initial operation of ICU immediately after Power ON, and communication
between PCU and ICU is inhibited.
STATUS
CDSEN
Toner concentration sensor detection signal (Cyan) (Output voltage is inversely proportional
to toner concentration.)
SENSE (ANALOG)
CDVF_
Color developing unit fuse cut drive signal (This signal is sued to blow off the fuse. At LOW,
the fuse is blown off.)
DRIVE
CDVFN
Color developing unit fuse cut detection signal (Used to check the fuse to detect that the
developing unit is a new one or not. LOW when new one.)
DETECT
CLJAM_
Paper jam detection signal (Transfer drum cleaner section) (LOW at detection)
DETECT
CLK
Clock signal (For IC10)
CLOCK
CMAGC_
Developing roller clutch drive signal (Cyan) (LOW at drive)
DRIVE
CMD
Command signal from ICU
DATA (COMMAND)
CRDY_
Command signal reception ready signal (LOW when PCU is ready for reception of
command signal (COM).)
STATUS
CTCONS_
Toner supply clutch solenoid drive signal (Cyan) (LOW at drive)
DRIVE
