QUENCHING LAMPS
No. Component Function
QL1 Quenching Lamp : K
Eliminates electrical charge and neutralizes the surface of the
drum in the Black PCU.
QL2 Quenching Lamp: C
Eliminates electrical charge and neutralizes the surface of the
drum in the Cyan PCU.
QL3 Quenching Lamp: M
Eliminates electrical charge and neutralizes the surface of the
drum in the Magenta PCU.
QL4 Quenching Lamp: Y
Eliminates electrical charge and neutralizes the surface of the
drum in the Yellow PCU.
SENSORS
No. Component Function
S1 ID Sensor: Black
Reads 1) light reflected from the bare surface of the ITB, and
2) reads light reflected from the black ID sensor patterns on the
ITB.
S2 ID Sensor: Color
Reads 1) light reflected from the bare surface of the ITB, and
2) reads light reflected from the color ID sensor patterns on the
ITB. This sensor has one additional receptor to collect diffuse
light reflected from color toner to improve calculation of the
toner density.
S3 ITB Lift Sensor (FC)
This sensor switches the ITB lift motor off when the ITB comes
into contact the drums of the four PCUs.
