1-1. Basic Structure
The BP unit is comprised of the transfer belt, transfer belt motor, belt platen, transfer belt fan (6), and the belt HP
sensor.
1. Paper received from the registration rollers is transferred and conveyed to the paper elevation unit or optional
face up paper ejection unit.
2. The BP section supports transfer of maintenance unit and is raised and lowered along with the maintenance
unit.
3. Coming into contact with the head holder contact pins maintains adequate distance and parallelism between
the heads and the paper transfer surface and parallelism between the drive and driven roller shafts.
4. If paper jams occur, the BP unit will be lowered.
5. While the transfer belt is being driven, the belt HP sensor detects the belt position once per revolution to adjust
ink ejection timing.
