b) Procedure after replacing the head management sensor
Since the distance between the head management sensor and the carriage unit varies among printers, the optical axis is factory-adjusted to adjust the non-discharging
detection position. When you have replaced the head management sensor or performed assembly/reassembly of surrounding parts that can change the distance be-
tween the head management sensor and the carriage unit, reasjustment is required.
Peform the readjustment in the service mode.
