Description
The purpose of this Service Calibration is to calibrate the OMAS Module. The calibration process consists
of printing a special calibration plot and then scanning it with the printer.The scanned result values are
compared with the actual printed values to obtain a PASS/FAIL result.
Perform the OMAS Module Calibration as follows:
NOTE: After the Paper Advance Calibration has been performed correctly, you MUST
perform the Clean Drive Roller procedure. If this is NOT done, the Printer will not perform
correctly and could cause Print Quality problems.
NOTE: Before starting the Clean Drive Roller procedure, make sure you first load media into
the Printer that the customer will normally use to print.
NOTE: In order to perform this Calibration, you should order the Paper Advance Calibration
Kit (Part Number Q1273-60296) which contains two cut sheets of HP Universal Instant-dry
Gloss Photo media (36-inches wide by 42-inches long).
NOTE: Disabling the Heaters ‘1.8.2’ will significantly speed up this procedure.
