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. See page 153
for
instructions on how to enter the service calibrations menu.
1. Scan Axis Calibration ⇒ See page 154
The purpose of this Service Calibration is to carry out a PWM check, and calibrate the intensity of
the Line Sensor.
2. Paper Advance Calibration ⇒ See page 157
The purpose of this Service Calibration is to calibrate the nominal advance of the media. This cali-
bration is necessary to control the exact movement of the media in order to avoid print quality prob-
lems like banding.
3. Drop Detector Calibration ⇒ See page 162
The purpose of this Service Calibration is to calibrate the Drop Detector (located in the Service Sta-
tion) in relation to the Carriage Assembly.
4. Line Sensor Calibration ⇒ See page 163
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.
5. Vacuum Calibration ⇒ See page 166
The purpose of this Service Calibration is to set the default nominal and real values of the Vacuum
Fan.
6. OMAS Calibration ⇒ See page 167
The purpose of this Service Calibration is to calibrate the Optical Media Advance Sensor.
7. Primer Calibration ⇒ See page 173
8. The purpose of this Service Calibration is to calibrate the Primer.
9. Platen Blue Line Calibration ⇒ See page 177
The purpose of this Service Calibration is to calibrate the blue line which is marked on the Print
Platen.
NOTE: REMEMBER THAT CERTAIN CALIBRATIONS ARE REQUIRED EVEN IF AN ASSEMBLY
HAS BEEN DISASSEMBLED TO GAIN ACCESS TO ANOTHER ASSEMBLY OR COMPONENT.
NOTE: If ALL the Calibrations need to be performed (for example, when both the HDD and
the ISS PCA have been replaced), you must perform them in the following order:
•
Vacuum Calibration.
• Drop Detector/Service Station Calibration.
• Line Sensor/Scan Axis Calibration.
• Paper Advance Calibration.
• Platen Blue Line Calibration.
