Vertical and Horizontal Color Registration

Phaser 6300/6350/6360 Color Laser Printer Service Manual
Vertical Color Registration
Vertical color registration adjustment is performed automatically when the
Color Registration page is printed or when a different Imaging Unit is
detected. No process for manual vertical color registration adjustment is
available. See the procedure on page 5-29 if problems persist with vertical
registration. Vertical color registration settings are stored in the Engine
Control Board's NVRAM.
Horizontal Color Registration
There are two adjustment options for horizontal
color registration, automatic and manual. The
values for these settings are stored in the
Image Processor Board's NVRAM.
Automatic registration calibration uses the CTD
(ADC) Sensor to measure the distance
between black in relation to the other colors
placed on the Transfer Roller. The accuracy of
this process is 2400 dpi (four times more
accurate than the manual process). However, if
the horizontal registration alignment is too far
out of adjustment, the automatic process fails
(the sensor does not detect the colors and fails
to correctly align the colors). In this case, adjust
the horizontal registration manually.
The manual registration calibration process has
an accuracy of 600 dpi. Use this procedure
whenever the Laser Unit has been removed or
replaced or the automatic process fails.
The Color Registration menu is used to adjust
the registration of cyan, magenta and yellow
against black. Settings range from -7 to +7 (left
to right). Zero(0) indicates the current color
registration setting.
Print the Color Registration page from the
Troubleshooting
menu.
