b) Paper thickness adjustment
The clearance between the head face of the BJ cartridge and the paper varies with
the thickness of the paper. Smaller clearance improves the printing quality however,
paper contacting the head face risks spoiling print quality or damaging the BJ
cartridge head face. This printer is equipped with a 2-position paper thickness
selector to provide constant paper clearance. The carriage shaft is supported by
means of an eccentric bearing. The paper thickness selector turns this eccentric
bearing to move the carriage up and down in order to adjust the head-to-paper
distance.
