3. PRINTER'S MECHANICAL SYSTEM

3.1 Overview

The printer's mechanical system is comprised of the BJ cartridges, carriage unit, purge

unit, paper-feed unit, and drive switching unit. The following describes each of these

units:

3.1.1 BJ cartridge unit

There are 3 types of BJ cartridges: the Black BJ cartridge with 160 nozzles and a 360

dpi nozzle pitch, the Color BJ cartridge with 48 nozzles and a 360 dpi pitch per color

(yellow, magenta, and cyan), and the Photo BJ cartridge with 48 nozzles and a 360dpi

nozzle pitch per color (photo-black, photo-magenta, and photo-cyan). The user can

install the cartridges in accordance to his/her printing needs. Always install the

Color BJ cartridge on the right side of the carriage. The left side of the carriage is for

either the Black BJ cartridge or Photo BJ cartridge, depending on the specific printing

requirements. Each BJ cartridge has detachable ink tanks, making it possible to

replace only the ink tank.

3.1.2 Carriage unit

The carriage, with two BJ cartridges installed in it, moves back and forth, along the

horizontal width of the paper, by the carriage belt driven by the carriage motor. The

carriage position is controlled by the carriage motor drive pulses after its initial

position is detected by the home position sensor mounted on the carriage board. The

print signals from the control board will be transmitted via the carriage ribbon cable

to the BJ cartridges installed in the carriage. The carriage controls the paper feed

motor drive switching unit, driving of the paper feed and purge unit, and switching of

the auto-sheet feeder drive. The carriage also controls the position for which capping,

wiping, or pumping is performed by the purge unit for BJ cartridge maintenance.
