PCBs
PCB
CCB (Cartridge Control
Board)
Mounted in the cartridge holder behind the right front
door of the printer. This PCB relays signals between
the control board on top of the printer and the ink
pump motors that supply ink to the ink tanks. It also
relays the ID chip signals that detect whether the ink
cartridges are installed properly in the correct slots of
the cartridge holder.
PCB CTL (Control Board)
Mounted on top of the printer and below the top cover
(protected by a metal plate). Controls overall
operation of the printer, mainly: 1) image data
processing, 2) interface management (USB,
duplexer, bypass tray, PFU, etc.) 3) all sensors,
motors, other devices.
PCB
DIB (Duplex Interface
Board)
Mounted in the duplex unit. This PCB controls the
operation of the duplexer. This PCB also contains the
duplexer cover switch that detects when the duplexer
cover is open and closed. The printer will not operate
if the duplexer is not installed properly, or if the
duplexer cover is open.
PCB
Duplexer Detection
Board
Mounted behind the printer. The metal prongs of the
DIB contact this board make the connection between
the DIB and the duplexer cover switch mounted on
the DIB. This contact must be closed for the printer to
operate. The duplexer is not an option. It must be
installed at all times, even when printing on only one
side.
