Service Calibrations
The Printer has several calibration procedures that must be performed under
certain conditions.
The following is a list of all internal service calibrations available in the
Printers. Instructions for entering the service calibrations menu are given on
Page 4-4.
1 Scan Axis Calibration  Page 4-4
The purpose of this Service Calibration is to carry out a PWM check, and
calibrate the intensity of the Line Sensor.
2 Service Station Calibration  Page 4-5
The purpose of this Service Calibration is to calibrate the Drop Detector
(located in the Service Station) in relation to the Carriage Assembly.
3 Paper Advance Calibration  Page 4-6
The purpose of this Service Calibration is to calibrate the nominal advance
of the media. This calibration is necessary to control the exact movement of
the media in order to avoid print quality problems like banding.
4 Drop Detector Calibration  Page 4-12
The purpose of this Service Calibration is to calibrate the Drop Detector
(located in the Service Station) in relation to the Carriage Assembly.
5 Line Sensor Calibration  Page 4-15
The purpose of this Service Calibration is to calibrate the intensity of the Line
Sensor. An incorrect calibration can result in edge-detection failures during
media loading and incorrect reading of prints that are used for alignment or
calibration.
6 Carriage Setup  Page 4-18
The purpose of this Service Calibration is to reset the ink short thresholds
after replacing the Carriage PCA.
7 Color Sensor  Page 4-18
The purpose of this Service Calibration is to calibrate the Color Sensor.
REMEMBER THAT CERTAIN CALIBRATIONS ARE REQUIRED
EVEN IF AN ASSEMBLY HAS BEEN DISASSEMBLED TO GAIN
ACCESS TO ANOTHER ASSEMBLY OR COMPONENT.
If ALL the Calibrations need to be performed (for example,
when both the Formatter and the Print Mech PCA have been
replaced), you must perform them in the following order:
 Drop Detector/Service Station Calibration.
 Line Sensor/Scan Axis Calibration.
 Paper Advance Calibration.
