Description
Detects paper passing through the fixing
assembly.
Controls the rotation of the developing rotary.
Detects the level of color toner.
Detects the waste toner cartridge (when full;
light-receiving section).
Detects the waste toner cartridge (when full;
light-emitting section).
Controls the primary charging bias, black
developing bias, and color developing bias.
Controls the primary transfer bias, secondary
transfer bias, secondary pre-transfer charging
bias, fixing separation bias, and ITD cleaning
roller bias.
Relays data among PCBs.
Controls the load on the multifeeder pick-up
mechanism.
Controls the laser scanner, controls the video
interface, and controls the temperature of the
fixing assembly.
Controls the load on the cassette pick-up
mechanism.
Detects the width of paper when the multi-
feeder tray is selected.
Detects the density of toner (each color).
Detects the size of paper in the cassette 2.
Detects the size of paper in the cassette 1.
Relays data among loads.
Detects the presence/against of each color
toner cartridge.
Checks the environment inside the machine.
Relays data among loads.
Controls the separation static eliminating
bias.
Relays data between reader unit and DC
controller PCB.
Assists the DC controller PCB.
