Service Calibrations
Service Calibrations
The Printer has several calibration procedures that must be performed under certain conditions.
REMEMBER THAT CERTAIN CALIBRATIONS ARE REQUIRED
EVEN IF AN ASSEMBLY HAS BEEN DISASSEMBLED TO GAIN
ACCESS TO ANOTHER ASSEMBLY OR COMPONENT.
The following is a list of all internal service calibrations available in the Printers. For instructions to enter the service calibrations menu, see Entering the Service Calibrations Menu on page
1Scan Axis Calibration. See Scan Axis Calibration on page
The purpose of this Service Calibration is to carry out a PWM check, and calibrate the intensity of the Line Sensor.
2Service Station Calibration. See Service Station Calibration on page
The purpose of this Service Calibration is to calibrate the Drop Detector (located in the Service Station) in relation to the Carriage Assembly.
3Paper Advance Calibration. See Paper Advance Calibration on page
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.
4Drop Detector Calibration. See Drop Detector Calibration on page
The purpose of this Service Calibration is to calibrate the Drop Detector (located in the Service Station) in relation to the Carriage Assembly.
5Line Sensor Calibration. See Line Sensor Calibration on page
The purpose of this Service Calibration is to calibrate the intensity of the Line Sensor. An incorrect calibration can result in
6Carriage PCA. See Carriage PCA on page
The purpose of this Service Calibration is to reset the ink short thresholds after replacing the Carriage PCA.
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.
