c) Removing the multi sensor reference plate

1) Remove screw [1] to remove the multi sensor reference plate [2].

d) Note on replacing the multi sensor

When the multi sensor has been replaced, be sure to replace the multi sensor reference plate(QL2-2840-000:MOUNT, MULTI SENSOR REFERENCE) as well.

f) Action to take after replacing the multi sensor

Because the distance between the multi sensor (in the carriage unit) and the nozzles (in each printhead) is varied from one unit to another, the printer has its optical
