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

d) Adjusting the wire roller

To prevent the wire roller mounted on the carriage from contacting the duct and others during carriage operation, perform the following adjusutment whenever tou

have removed or replaced the carriage unit. This adjustment is not required when you have replaced only the multi sensor.

* Make adjustments with the carriage lock released.

* Make adjustments with the tube disconnected from the tube guide.

(1) Loosen the two screws[1].

(2) Turn the gear[2] until the lift cam flag[3] reaches the position shown below.

* Bottom position where the sensor[4] light is blocked by the flag (lowest position to which the carriage unit descends).
