The identification chip of the black (K) ink cartridge.
The identification chip of the cyan (C ink cartridge.
The identification chip of the magenta (M) ink cartridge.
The identification chip of the yellow (Y) ink cartridge.
Mounted inside the multi bypass tray. This is the main control board
that controls operation of the bypass tray and interfaces with the
printer.
Mounted under the operation panel LCD and keypad. Controls
the operation of the operation panel. The right front door sensor
is also mounted on this PCB.
Mounted in the optional paper feed unit. This is the board that
controls operation of the paper feed unit and interfaces with the
printer.
Mounted under the left front cover. Supplies both 37V and 5.1V
power to the HVPS and all motors in the printer.
A small PCB mounted below and slightly to the left of the vertical
encoder wheel. The vertical encoder sensor is mounted and posi-
tioned on this PCB so the rim of the vertical encoder wheel passes
through its gap as the wheel rotates. The sensor reads the code on
the rim of the wheel to control the operation of paper feed timing
and operation of the vertical feed motor.
