2.3.2.3.2 Structure of Carriage Unit
0012-6265
a) Printhead mount
The printhead is secured to the carriage by the printhead fixer cover and the printhead fixer lever. When the
printhead is secured to the carriage, the signal contact of the head relay PCB is pressed against that of the
printhead to convey print signals. Further, the ink passage from the ink tanks is connected to the printhead via
the ink tubes.
b) Ink port
Ink is supplied to the printhead via an ink tube, which runs between the tube guides via joints to reach the
carriage and follows up its motion.

c) Control unit
The carriage relay PCB is connected to the head relay PCB by means of a flexible cable. The flexible cable
between the main controller and the carriage relay PCB follows up the motion of the carriage together with the
tube guide.
A photocoupler encoder mounted in the lower part of the back of the carriage detects a linear scale reading as
the carriage moves.
d) Carriage drive
Mechanical misregistrations in the vertical/horizontal and bidirectional print positions of the printhead mounted
can be corrected by selecting Adjusting Printer from the [MAIN MENU] to [Adjust Printer].
A DC-operated carriage motor drives the carriage in the horizontal direction of paper by way of the carriage.
The carriage home position, is where the carriage is slowly brought to the right end at power-on initialization.
When the linear scale position is set as a reference home position for use in subsequent position control
operations, the driving of the carriage motor is controlled by control signals generated from the main controller.
