b) Procedure after replacing the head management sensor
The optical axis is compensated at factory shipment in order to adjust the non-discharge detection position because there are fluctuations among machines
in the distance between the head management sensor and carriage unit. Therefore, adjustment must be made when the head management sensor is replaced
or disassembling/assembling components that may cause error in the distance between the head management sensor and carriage unit.
Enter the service mode as follows:
