3.2 When Adjustment of the Print Head Position is Required

a) Overview

When replacing the print heads, the point of ink ejection may be off, preventing clean characters,

depending on the state in which BJ cartridge is installed. In order to eliminate this drift, it is necessary to

adjust the head position after attaching the BJ cartridge. Set 2 or more sheets of normal paper sized A4 or

LTR on the Auto Sheet Feeder, and perform head position adjustment following the steps in Fig. 4-4.
