b) 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.
