4.5 Adjustment and Setup Items

4.5.1 Procedure after Replacing the Feed Roller HP Sensor or Feed Roller
Encoder

Procedure after replacing the feed roller HP sensor or feed roller encoder

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 replacing the feed roller HP sensor or feed roller encoder.
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
Media size : Media having awidth equal to or larger than that of A2-size paper

4.5.2 Procedure after Replacing the Carriage Unit or Multi Sensor

a) Multi Sensor Recalibration
Since multi sensors have individual electrical specificity, the following are recalibrated at the factory, namely,
the optical axis of the sensor, the sensor gain for measuring the printhead height and color reproduction.
Accordingly, carry out the following adjustments in the service mode whenever replacing the carriage unit or
multi sensor.
The multi sensor reference plate must be replaced at the same time whenever the carriage or the multi
sensor is being replaced.
-Service mode : SERVICE MODE > ADJUST > GAP CALIB
-Service mode : SERVICE MODE > ADJUST > SENSOR CALIB
Test chart : CL-7( Tool No. : FY9-9323 Use anew chart.)
-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

4.5.3 Procedure after Replacing the Head Management Sensor

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
between the head management sensor and the carriage unit, reasjustment is required
Peform the readjustment in the service mode.
Service mode : SERVICE MODE > ADJUST > NOZZLE CHK POS.
