3-1-5-1. CR Origin Sensor Adjustment

This menu adjusts the detecting position of the Origin Sensor; which defines the origin of the Carriage.
The Origin Sensor detects the sealed area on the Encoder Strip when you turn ON the printer. The position of
the sealed area has been adjusted in manufacturing but the position may shift by dismounting the Encoder
PCB and replacing the Encoder Strip. Execute this adjustment after you modify the printer. Be sure to execute
this after you replace the Main PCB.
Without this adjustment, the position of the Caps and print may shift in horizontal direction. If you find that only
the capping position should shift, adjust the position of the Maintenance Unit first.
