Signal Name
Description
5V-LD
+5V power source to the Laser Diode (0V when the Front Cover is
open or when the Fuser Unit is not in place)
STS
Signal from the temperature sensor which detects the temperature of
the Fuser Heat Roll (analog signal)
BTR SIG
Signal for setting the Transfer Current (analog signal)
/REFEED SNR
Signal for monitoring the paper passing through the Duplex Unit (Low
level when paper is at the sensor, and HIGH level when paper is not
at the sensor)
NO PAP1
Signal for detecting the presence/absence of paper in Tray 1
/BCR DC ON
Signal for switching on or off the application of the Charge Voltage
(DC component) to the BCR (Normally LOW level, and HIGH level
only when applying the charge voltage)
/DB AC ON
Signal for switching on or off the application of the Development
Voltage (AC component) to the Magnet Roll (Normally LOW level,
and HIGH level only when the Development Voltage is applied)
BTR +/- ON
Signal for switching the polarity of the Transfer Voltage (LOW level
when selecting “+” and HIGH level when selecting “-”)
/BCR AC ON
Signal for switching on or off the application of the Charge Voltage
(AC component) to the BCR (Normally LOW level, and HIGH level
only when applying the Charge Voltage)
/BTR ON
Signal for switching on or off the application of the Transfer Voltage
(Normally LOW level, and HIGH level only when applying the
Transfer Voltage)
/DB DC ON
Signal for switching on or off the application of the Developing
Voltage (Normally LOW level, and HIGH level only when applying the
Transfer Voltage)
CRU SNR
Signal for detecting if the CRU is in place or not (LOW level when the
CRU is in place and HIGH level when the CRU is not in place)
/EXIT SNR
Signal for monitoring the paper passing the exit part of the Fuser Unit
/DUP PRES
Signal for detecting if the Duplex Unit is installed or not (LOW level
when the Duplex Unit is in place and HIGH level when the Duplex
Unit is not in place)
/DTS ON
Signal for switching on or off the application of a voltage to the
eliminator plate (Normally LOW level, and HIGH level only when
applying the voltage)
BTR MONITOR
Signal used for measuring the Transfer Current on the BTR (analog
signal)
/DUP MOT ON
Signal for switching on or off the Motor of the Duplex Unit
DUP MOT CLK
Reference clock for driving the Motor of the Duplex Unit
5V-INTLK
