Line Sensor Calibration

The purpose of this Service 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.

Perform the Line Sensor Calibration whenever:

„Edge detect procedure fails during media loading.

„Carriage is disassembled or replaced.

„Line Sensor is disassembled or replaced.

„Banding is detected in prints.

„Misalignment between colors is detected.

Service calibrations also need to be performed after removing or replacing certain printer components. If you have removed or replaced printer components, check the Service Calibration Guide to Removal and Installation on page 6-5 to see which tests and calibrations you need to perform.

Perform the Line Sensor Calibration as follows:

Make sure you load one of the following media into the Printer before performing this calibration:

„HP Bond Paper.

„HP Glossy Media.

„HP Coated Paper.

„HP Productivity Photo Gloss.

„HP Heavyweight Coated Paper.

„HP Super Heavyweight Coated Paper.

„HP Bright White Inkjet Paper.
