3.4 Carriage

3.4.1 Carriage functions

1) Print head installation
The carriage holds the BJ cartridge mechanically with the carriage ribbon cable, and
is connected to the circuit on the logic board.
2) Carriage driver
Driven by the carriage motor and carriage belt, the carriage moves across the paper
horizontally.
3) Paper thickness adjustment
With the paper thickness lever at the top of the carriage, the gap between the paper
and printing head can be adjusted.
4) Paper feed motor driver
When the carriage moves to the cleaning position at the right end, the slide arm is
unlocked. The paper feed motor's drive power, normally used for paper feeding
during printing, can be diverted to drive the purge unit and sheet feeder.
