3.4 Carriage

3.4.1 Carriage 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.
