Electrical Component Functions
J007/J010/J011 6-42 SM
No. Component Function
MT
Ink Pump Motor (Y) –
DCM5
J007/J010: Not present.
J011: Runs forward to pump yellow (Y) to Print Head
4, reverses to pump Yellow (Y) to Print Head 1.
MT
Maintenance Motor –
MT STM1
Mounted in the maintenance unit. Drives the
maintenance unit: 1) Rotates forward to drive the shaft
that raises and lowers the caps during print head
cleaning, 2) Reverses to drive the simple tube pump
that siphons ink from the print head through the right,
3) Raises and lowers the wiper that removes ink
collected around the print head.
MT
PFU Paper Feed
Motor – STM2
Mounted in the PFU. Drives the pick-up roller and
paper feed rollers that feed paper from the PFU tray
into the printer.
MT
Vertical Motor
(DCM2)
Mounted behind the vertical encoder wheel and to the
left of the PSU. This motor, controlled by the rotation fo
the vertical encoder wheel and SENC board, drives
the paper rollers that drive the transport belt.
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.
PCB HRB (Head Relay Mounted behind the print heads on the carriage. This
