3.4.1Carriage functions

1) Attachment of print heads

The carriage mechanically attaches the BJ cartridges, which are connected to the logic board by ribbon cables.

2) Carriage drive

The carriage moves horizontally across the print media driven by the carriage motor via a carriage belt.

3) Paper feed motor drive switching

When the carriage moves further to the right of the capping position, it moves the slide lock lever of the purge unit right to release the transmission arm lock and switch the drive from the paper feed motor to the sheet feeder and purge unit.

4) BJ cartridge maintenance

In the BJC-7100 printer, the ink optimizer head wiper is operated according to the position of the carriage.

When the carriage moves left, the side of the ink optimizer head presses against the wiper lever on the left of the printer to set the wiper. When the carriage then moves right, the hook on the bottom of the carriage pulls the latch lever so that the ink optimizer head wiper wipes the face of the ink optimizer head.
