This Service Utility checks that the Embedded SpectroPhotometer (ESP) is functioning within predefined
color specifications. The test involves measuring the lightness of the white of the paper.
NOTE: To perform this test correctly the printer must have the latest firmware available.
1. Make sure that the paper loaded is suitable for the test: there are certain paper types that cannot
be used for this type of test. The best results can be acheived by using HP Universal Instant-dry
Gloss Paper (part number Q1273-60232). There are some other paper types that can be used:
