d) Note on replacing the carriage unit and the multi sensor
When either carriage unit or multi sensor has been replaced, be sure to replace the multi sensor reference plate(QL2-2840: MOUNT, MULTI SENSOR REFER-
ENCE) as well.
e) 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 sensor 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) Carry out the following service mode without media loading.
- Service mode : SERVICE MODE > ADJUST > GAP CALIB.
2) Load the following media.
Media type : Photo glossy paper
Media size : Media having a width equal too larger than that of A2-size paper
3) Carry out the following service mode.
