5-10 Service Calibrations HP DesignJet CP Series Printers
C03. Line Sensor
The purpose of this calibration is to calibrate the intensity of the line sensor
in the carriage PCA. An incorrect calibration can result in edge-detection
failures during media loading and incorrect reading of prints that are used
for alignment or calibration.
This calibration also identifies which type of Line Sensor has been installed
and stores this information in the EEROM.
Perform the line sensor calibration whenever the:
D Edge detect procedure fails during media loading.
D Carriage is disassembled or replaced.
D Electronics Module is replaced.
D Banding is detected in prints.
D Misalignment between colors is detected.
D There is a color consistency problem between prints.
Load white media before performing this calibration.
Perform the Line Sensor Calibration as follows:
MAKE SURE THAT THE WINDOW IS CLOSED BEFORE YOU
PERFORM THIS CALIBRATION.
REPLACE THE LENS COVER BEFORE YOU PERFORM THIS
CALIBRATION IN ORDER TO PREVENT ANY AEROSOL
PROBLEMS.

2 If media is not loaded the calibration will stop and the message “Load
Media” will be displayed on the front-panel. Load media in order to
continue the calibration.
3 While the Calibration is being performed, a row of “***” will be displayed
on the front-panel.
4 Once the Calibration is completed, a message similar to the following is
displayed on the front-panel.
