3. PRINTER'S MECHANICAL PARTS

3.1 Overview of the Printer's Mechanical Parts

The printer's mechanical parts consist of the BJ cartridge, carriage, purge section, and
paper feed section. Each part is explained below.

3.1.1 Carriage

The carriage holds one BJ cartridge in place. The carriage belt driven by the carriage
motor (DC motor) moves the carriage horizontally back and forth across the paper.
Regarding the carriage's position control, the initial position is detected when the
carriage goes against the right wall which is the home position.
After that, the carriage position is detected by reading the pulse from the encoder film.
The paper spacing position is read from the carriage position when the carriage goes
against the left wall.

3.1.2 Purge section

The purge section, driven by a dedicated purge motor, consists of the wiper, pump,
cap, and carriage lock.
The wiper maintains the head face surface to ensure high-quality printing. The ink
suction feature enables the ink to be readily ejected from the nozzles.
When the BJ cartridge is not in use, the nozzles are protected by a cap, and the
carriage is locked in place.
The motor's running direction controls the ink suction operation or capping/wiping/
valve open/closing operation.
