A photo-coupler-type encoder is mounted at the top of the rear of the carriage to detect the slit on the linear scale
during carriage movement, thus controlling the print timing.
d) Carriage drive unit
Mechanical misalignment of the printhead in the vertical and horizontal direction and in bidirectional printing
can be corrected by changing the print timing using the "Adjust Printer" option in the Main menu.
The carriage motor (DC motor) moves the carriage back and forth on the platen via the carriage belt.
The carriage home position is the capping position to which the carriage is slowly moved when the power is
turned on.
When the position read on the linear scale is set as the home position for position control, the carriage motor
moves based on control signal output from the main controller.
