c) Note on replacing the carriage unit and the multi sensor
When either carriage unit or multisensor has been replaced, be sure to replace the multisensor reference plate as well.
d) Action to take after replacing the carriage unit and 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
axis corrected and paper gap adjustment sensor gain and color calibration adjusted prior to shipment. When the carriage unit or multi sensor has been replaced,
they should require adjustment.
Execute service mode under the following conditions to launch automatic adjustment:
1) Optical axis correction
- Service mode: SERVICE MODE > ADJUST > PRINT PATTERN > OPTICAL AXIS
Media type: Gloss photo paper
2) Paper gap adjustment
- Service mode: SERVICE MODE > ADJUST > GAP CALIB.
