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, readjustment is required.
Perform the readjustment in the service mode.
Service mode : SERVICE MODE > ADJUST > NOZZLE CHK POS.
