1) Turn off the power, and then move the carriage onto the platen. Refer to "Disassembly/Reassembly > Points to Note on Disassembly and Reassembly > Opening

the Cap/Moving the Wiper Unit".

2) Remove the printhead to protect it.

3) Remove one screw [1] and disconnect one connector [2], and then the multi sensor [3].

b) Removing the Multi Sensor Reference Plate

1) Remove one screw [1], and then remove the multi sensor reference plate [2].

c) Action following the replacement of the carriage unit/multi sensor

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

its optical axis corrected to adjust the image write position. When the carriage unit or multisensor has been replaced or disassembled and reassembled, they require

adjustment.

Execute service mode under the following conditions:

* The multi sensor reference plate(QL2-3160-000:MOUNT, MULTI SENSOR REFERENCE) must be replaced at the same time whenever the carriage or the multi

sensor is being replaced.

- Service mode : SERVICE MODE > ADJUST > GAP CALIB.

- Service mode : SERVICE MODE > ADJUST > PRINT PATTERN > OPTICAL AXIS
