3. PRINTER MECHANICAL SYSTEM
3.1 Overview
This section explains the printer’s mechanical components.
3.1.1 Mechanical components
1) BJ cartridge
The printer comes with three types of BJ cartridges: black, color, and photo.  The
user installs the black or color BJ cartridge according to the required application.
The black BJ cartridge has an integrated head while the color BJ cartridge has
replaceable ink cartridges.
2) Purge unit
Driven by the carriage motor, the purge unit helps to maintain high-quality printing
by capping and wiping the BJ cartridge’s bubble jet face.  It ensures that the ink in
the nozzles is ejected easily.
When the printer is not in use, the purge unit caps the BJ cartridge’s nozzles for
protection.
3) Carriage
Driven by the carriage motor, the carriage moves horizontally across the paper.
Through the carriage ribbon cable, the printing signals from the logic board are
transmitted to the BJ cartridge in the carriage.
By controlling the purge unit's slide lock pin, the carriage controls the engagement
of the paper feed motor’s drive power between the paper feed/purge unit and the
sheet feeder.
