Adjustments
Vertical and Horizontal Color Registration
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 5-28) 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 two ADC Sensors to measure the distance
between black in relation to the other colors placed on the Transfer Unit belt. The
accuracy of this process is 600 dpi. 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.
