Chapter 44-344.5 Adjustment and Setup Items4.5.1 Adjustment Item List 0017-8323iPF9000 / iPF9000S / iPF9100The following adjustment procedures need to be performed when parts have been replaced or remove and then reinstalled:T-4-24.5.2 Action to take after replacing the Carriage Unit or Multi Sensor 0013-7133iPF9000 / iPF9000S / iPF9100a) Note on replacing the carriage unit and the multi sensorThe multi sensor reference plate must be replaced at the same time whenever the carriage or the multi sensor is being replaced.b) Multi Sensor RecalibrationBecause 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 opticalaxis corrected and paper gap adjustment sensor gain and calibration adjusted prior to shipment. When the carriage unit or multi sensor has been replaced, theyshould 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 AXISMedia type: Gloss photo paper2) Paper gap adjustment- Service mode: SERVICE MODE > ADJUST > GAP CALIB.4.5.3 Action to take after replacing the Feed Roller Encoder or Feed Roller 0012-6594iPF9000 / iPF9000S / iPF9100Action to take after replacing the feed roller encoder or feed rollerFeed 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 TUNINGMedia type : Photo glossy paperIf 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 TUNING2Media type: Gloss photo paperCheck the printed pattern and enter values for adjustment.4.5.4 Action to take after replacing the Head Management Sensor 0013-7146iPF9000 / iPF9000S / iPF9100Since the distance between the head management sensor and the carriage unit varies among printers, the optical axis is factory-adjusted to adjust the non-dischargingdetection 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 requiredPerform the readjustment in the service mode.Service mode : SERVICE MODE > ADJUST > NOZZLE CHK POS.Adjustment item Adjustment timingMulti sensor recalibration Multi sensor replacement/removalCarriage unit replacement/removalAdjusting feed roller eccentricity Feed rollerFeed roller encoderHead management sensor recalibration Head management sensor replacement/removalCarriage unit replacement/removal
