B. Capping Function

1. Outline

The carriage of this machine stands by at the home position. Duming this time, the caps of
the purge unit are pressed against the BJ print heads to prevent the nozzles from drying out and
to keep out dust.

2. Operation

When printing is completed, the carriage is returned to the home position and all the caps are
lifted and pushed against the head face. The caps are lifted and lowered by the movement of the
carriage.
