15
Developing roller
Attaches toner to the latent
electrostatic images on the OPC
drum to convert them into visible
images.
16
Transfer roller
Transfers toner images on the
OPC drum to paper.
17
Transfer pressure
spring
Applies a pressure to the transfer
roller, paper, and the OPC drum to
improve transfer efficiency.
18
Separation electrode
Reduces the paper charging
potential to facilitate separation of
paper from the OPC drum.
19
Temperature fuse 1
(fusing section)
Mold
Assures safety in overheating.
20
Temperature fuse 2
(fusing section)
Mold
Assures safety in overheating.
21
Pressure roller
Applies a pressure to the heat
roller and paper to improve fusing
efficiency.
22
Fusing pressure
spring
Applies a pressure to the heat
roller paper, and the pressure
roller to improve transfer efficiency.
23
Paper exit roller
Discharges paper after fusing.
24
POUT
POUT IN

MHPS
Scanner home
position sensor
Photo
transmission
sensor
Detects the scanner home
position. By this signal the image
scanning operation is controlled.

30
SL SENSOR
PDA/PDK
Scanner lamp light
quantity sensor
Photo diode
Detects the scanner lamp light
quantity. This signal is inputted to
the scanner lamp control PWB to
control the scanner lamp drive
voltage to maintain a constant
level of light quantity.
HIGH (5V) when
the home position
is detected.
31
Scanner lamp
Radiates light necessary for the
CCD to scan the document
images.
32
Lens
Transfers document images to
CCD.
33
CCD
SENSOR
CCD OUT
CCD (image) sensor
CCD
