and driver lines are stopped.)
DETECT/SWITCH
DVMLK_
LOW when developing motor rotation reaches the specified level (normal rotation).
STATUS

Clock signal for NV-RAM
CLOCL
FMSDA
NV-RAM data signal (Various control data, counter data, etc.)
DATA
FSCOM
Fusing motor drive power (+24V)
POWER
FSMA
Fusing motor drive signal A (Pulse signal)
DRIVE
FSMA_
Fusing motor drive signal A_ (Pulse signal)
DRIVE
FSMB
Fusing motor drive signal B (Pulse signal)
DRIVE
FSMB_
Fusing motor drive signal B_ (Pulse signal)
DRIVE
FSMD
Fusing motor drive clock signal
CLOCK
FSMDA
Fusing motor drive control signal A (Pulse signal)
CONTROL
FSMDA_
Fusing motor drive control signal A_ (Pulse signal)
CONTROL
FSMDB
Fusing motor drive control signal B (Pulse signal)
CONTROL
FSMDB_
Fusing motor drive control signal B_ (Pulse signal)
CONTROL
FSUF_
Fusing unit fuse cut drive signal (Used to blow off the fuse at LOW.)
DRIVE
FSUFN
Fusing 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
GAMMA
Image density sensor detection signal (During image correction, toner patch image density
is detected. During print operation, paper jam detection is performed.)
In color toner image detection, the greater the toner concentration is, the higher the sensor
output is. In black toner image density detection, on the contrary, if the sensor output
remains at high level during printing, it is judged as a paper jam.
SENSE (ANALOG)
GBL_
Main charger grid voltage control signal (Output voltage switch signal)
CONTROL
GBM_
Main charger grid voltage control signal (Output voltage switch signal)
CONTROL
