The following adjustment procedures need to be performed when parts have been replaced or removed and then reinstalled:
4.5.2 Procedure after Replacing the Carriage Unit or Multi Sensor
0023-2640
iPF765 / iPF760 / iPF750 / iPF755
a) Note on replacing the carriage unit and the multi sensor
- The multi sensor reference plate(QL2-3160: MOUNT, MULTI SENSOR REFERENCE) must be replaced at the same time whenever the carriage or the multi
sensor is being replaced.
b) Multi Sensor Recalibration
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 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 : Photo glossy paper
Media size : Media having a width equal toor larger then that of A2-size paper
2) Paper gap adjustment
- Service mode: SERVICE MODE > ADJUST > GAP CALIB.
c) Carriage Motor Adjustment
- After the carriage and carriage motor and carriage belt and linear encoder sensor has been removed or replaced, execute the following service mode.
Service mode: SERVICE MODE > ADJUST > CR MOTOR COG
4.5.3 Procedure after Replacing the Feed Roller or Feed Roller Encoder
0012-6594
iPF765 / iPF760 / iPF750 / iPF755
Feed roller eccentricity is factory-adjusted (correction of variation in the paper feed amount per rotation). It is necessary to adjust feed roller eccentricity after re-
placing the feed roller encoder or feed roller.
In the service mode, perform automatic adjustment of feed roller eccentricity.
Service mode : SERVICE MODE > ADJUST > PRINT PATTERN > LF TUNING
Media type : Photo glossy paper
If adjustment cannot be done properly by selecting "SERVICE MODE > ADJUST > PRINT PATTERN > LF TUNING" (auto adjustment), carry out manual ad-
justment.
Service mode SERVICE MODE > ADJUST > PRINT PATTERN > LF TUNING2
Media type: Gloss photo paper
Check the printed pattern and enter values for adjustment.
4.5.4 Procedure after Replacing the Head Management Sensor
0013-7146
iPF765 / iPF760 / iPF750 / iPF755
Since the distance between the head management sensor and the carriage unit varies among printers, the optical axis is factory-adjusted to adjust the non-discharging
detection position. When you have replaced the head management sensor or performed assembly/reassembly of surrounding parts that can change the distance be-
tween the head management sensor and the carriage unit, readjustment is required
Perform the readjustment in the service mode.
Service mode : SERVICE MODE > ADJUST > NOZZLE CHK POS.
