Signal Name Description
/HEAT Control si
g
nal which switches on and off the Heater Quartz.
The Heater Quartz is switched on when this si
g
nal is Low and
off when Hi
g
h.
NO TONER Si
g
nal from the Sensor Toner in the Cartrid
g
e Assembl
y
EP.
(CRU). This si
g
nal is Low when toner is detected in the
Cartrid
g
e Assembl
y
EP. (CRU) and Hi
g
h when the toner is not
detected (runnin
g
out).
/PRE REG Si
g
nal from the Sensor Pre-re
g
. in the P/H section. This si
g
nal
is Hi
g
h when paper is not detected b
y
the Sensor Pre-re
g
. and
becomes Low when detected.
/CR Control si
g
nal which switches on and off the Bias Char
g
e
volta
g
e (DC component) applied to the BCR. The Bias Char
g
e
volta
g
e (DC) is not applied when this si
g
nal is Hi
g
h and applied
when Low.
/FAN Switches the speed of the Fan IOT between Hi
g
h and Low.
When this si
g
nal is Low, the drivin
g
volta
g
e to the Fan (FAN) is
24 VDC, and the Fan rotates at Hi
g
h speed.
When this si
g
nal is Hi
g
h, the drivin
g
volta
g
e to the Fan (FAN) is
12 VDC, and the Fan rotates at Low speed.
/DB AC Control si
g
nal which switches on and off the Development Bias
volta
g
e (AC component) applied to the Ma
g
. Roll. The
Development Bias volta
g
e (AC) is not applied when this si
g
nal
is Hi
g
h and applied when Low.
/DB DC Control si
g
nal which switches on and off the Development Bias
volta
g
e (DC component) applied to the Ma
g
. Roll. The
Development Bias volta
g
e (DC) is not applied when this si
g
nal
is Hi
g
h and applied when Low.
Fan Alarm Monitor si
g
nal (Fan Alarm) from the Fan IOT which rises Hi
g
h
when the Fan stops.
5V-LD +5V power suppl
y
for drivin
g
the LD (interrupted when the Exit
Cover is open)
NO PAPER 1 Si
g
nal from the Sensor No-paper for Cassette 1. This si
g
nal is
Low when paper is detected and becomes Hi
g
h when paper is
not detected (the Cassette is empt
y
).
/REG IN Si
g
nal from the Sensor Re
g
istration. This si
g
nal is Hi
g
h when
paper is not detected b
y
the Sensor Re
g
istration and becomes
Low when detected.
