4.5.2 Adjusting Feed Roller Eccentricity
0009-9383
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
0009-9384
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
0009-9385
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
