2.3.3 Adjustable bushings supporting the carriage shaft

The adjustable bushings supporting the carriage shaft are adjusted and secured to
the printer frame so that the ideal gap, or head gap, between the BJ cartridge nozzle
and platen is maintained for best print quality.
The fixing screws are painted red to protect against careless removal. Do not loosen
the fixing screws.

2.3.4 Feed gear

Be careful not to touch the gears in the paper feed unit, especially the feed roller gear,
during disassembling or reassembly. Although covered, even slight damage to it could
affect paper feeding when printing at high resolution.
