Phaser 7700 Color Laser Printer Service Manual
9-291
Diagnostics Mode
Laser Check
This is a gray print with all four colors
turned on at about 25% fill.
Things to look for:
A hue shift that indicates one of the
primary CMYK colors is missing. A
missing primary indicates that the laser
is faulty.
Halftones
This test prints 6 pages of 100% solid
fill of: Yellow, Magenta, Cyan, Black,
Red and Green. This print sequence is
very useful in determining if there is any
streaking of (usually) yellow or cyan
that has interfered with RegiCon
(registration control).
When you get DC685-1 results showing
"A-Patch IN/OUT block counts" of less
than 24 (or "B-Patch IN/OUT block
counts" of less than 4), use these prints
to decide if attention needs to be
focussed on the toner delivery
mechanisms. Until toner is evenly
deposited on the developer roller,
RegiCon cannot pass.
Things to look for:
A “mottled” color, especially on the red
and green pages.
