MX-7000N  PROCESS CONTROL SENSOR, REGISTRATION SENSOR SECTION  N – 2
2. Operational descriptions
A. Process control sensor control
The shutter is provided on the monochrome (PCS_K) and color
(PCS_CL) process control sensor. When the shutter is opened (the
image density is corrected), the toner patch formed on the transfer
belt is scanned by the process control sensor and the information is
passed to the PCU.
When the shutter is closed, the gray resin section on the back of
the shutter is scanned to perform calibration of the sensor itself.
The shutter operation is controlled by the process control shutter
solenoid (PCSS).
B. Registration sensor control
The registration sensor is attached to the F side (REG_F) and the
R side (REG_R). When the shutter is opened, the registration
image formed on the transfer belt is scanned by the sensor and the
information is passed to the PCU.
3. Disassembly and assembly
A. Process control registration sensor unit
