4.5 Adjustment and Setup Items

4.5.1 Adjustment of head holder tilt lever

This adjustment is performed when the edge sections of the image are not sharp when printing in Draft mode (2-pass).

After adjusting the head holder tilt lever, mark the number visible from the window of the head holder tilt lever with the number inside the sensor cover.

4.5.2 Adjusting Feed Roller Eccentricity

The decentration of the feed roller (fluctuation in the amount of media fed per rotation) is compensated at factory shipment in order to improve media feed

precision. Therefore, adjustment must be made when the feed roller, feed roller HP sensor, or feed roller encoder which affect the decentration

compensation is replaced or disassembled/assembled.

Enter the service mode under the following condition:

Service mode: SERVICE MODE > ADJUST > PRINT PATTERN > LF

Carriage: LOW position

Media type: Photo Glossy Paper

Media size: 24 inch

4.5.3 Adjusting the Registration Sensor Optical Axis

The optical axis is compensated to adjust the image printing position at factory shipment because there are fluctuations among machines in the distance

between the registration sensor (in the carriage unit) and nozzle (in the print head). Therefore, adjustment must be performed when replacing or

disassembling/assembling the carriage unit or registration sensor.

Enter the service mode under the following condition:

Service mode: SERVICE MODE > ADJUST > PRINT PATTERN > OPTICAL AXIS

Head height: LOW position

Media type: Photo Glossy Paper

Media size: 24 inch

4.5.4 Adjusting the Head Management Sensor Optical Axis

The optical axis is compensated at factory shipment in order to adjust the non-discharge detection position because there are fluctuations among machines

in the distance between the head management sensor and carriage unit. Therefore, adjustment must be made when the head management sensor is replaced

or disassembling/assembling components that may cause error in the distance between the head management sensor and carriage unit.

Enter the service mode as follows:

Service mode: SERVICE MODE > ADJUST > NOZZLE CHK POS. > YES
