No. Component Function
Board) board performs many important functions: 1) contains
the horizontal encoder sensor that reads the horizontal
encoder (the film strip) that controls the
reverse/forward timing of the horizontal motor that
moves the carriage during printing, 2) relays the
readings of the 1st registration sensor mounted on the
left edge of the carriage, 3) contains a small thermistor
that detects the temperature around the print heads, 4)
receives and relays signals from the ink collection tank
to the control board.
PCB
HVPS (High Voltage
Power Supply)
Mounted under the top cover and above the transport
belt. Generates the voltages applied to the transport
belt that hold the paper on the belt during printing. Two
interlock switches, one connected to the top cover and
the other to the duplexer cover, prevent the HVPS
from operating if either or both covers are open.
PCB ID Chip 1 The identification chip of the black (K) ink cartridge.
PCB ID Chip 2 The identification chip of the cyan (C ink cartridge.
PCB ID Chip 3
The identification chip of the magenta (M) ink
cartridge.
PCB ID Chip 4 The identification chip of the yellow (Y) ink cartridge.
PCB
Multi Bypass Tray
Control Board
Mounted inside the multi bypass tray. This is the main
control board that controls operation of the bypass tray
and interfaces with the printer.
PCB
OPU (Operation
Panel Unit
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.
PCB PFU Main Board
Mounted in the optional paper feed unit. This is the
board that controls operation of the paper feed unit
and interfaces with the printer.
PCB
PSU (Power Supply
Unit)
Mounted under the left front cover. Supplies both 37V
and 5.1V power to the HVPS and all motors in the
printer.
PCB
SENC (Sub Scan
Encoder)
A small PCB mounted below and slightly to the left of
the vertical encoder wheel. The vertical encoder
sensor is mounted and positioned 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.
