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, reasjustment is required.

Peform the readjustment in the service mode.

4.3.18 Multi Sensor

iPF6100 / iPF6200 / iPF6000S

a) Removing the multi sensor

1) Remove the screw[1], disconnect the flexible cable[2], and then remove the multi sensor[3].

Since the multi sensor has 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 sensor calibration. Accordingly, carry out the following adjustments in the service mode whenever replacing the carriage unit

or multi sensor.

* The multi sensor reference plate(QL2-1561-000:PLATE, REFLECTION, MULTI-SENSOR) must be replaced at the same time whenever the carriage or the multi

sensor is being replaced.

* When replacing the carriage unit, refer to Adjustment and Setup > Procedure after Removing or Replacing the Carriage Unit.
