Registration Control (RegiCon) Adjustment Overview

The DC685 RegiCon tests are the means by which registration is
accomplished. Registration means establishing the alignment of the four
primary colors with regard to horizontal and vertical positioning, tilt or skew,
length of lines and linearity. When the registration process is completed, all
color planes are positioned properly.
Note For any registration procedure to succeed, the printer
must print with no image defects. Verify by printing color
solid fill pages, see "Print Color Test Prints" on
page 9-289. To resolve a print image problem, see "Print
Image Quality Problems" on page 3-108.
The printer registration process consists of the Belt Edge Learn, Coarse Skew
Adjustment, Fine Skew Adjustment, In/Out Skew Adjustment, and Center
Skew Adjustment, with each test reporting success. On failure of any of Skew
Adjustment, the Coarse RegiCon Initialization must be performed.

Coarse RegiCon Initialization

Coarse RegiCon Initialization is the procedure by which the printer aligns the
magenta, yellow and black vertical and horizontal scan lines to the cyan
reference scan line. Horizontal and vertical alignment ensures that the
magenta, yellow and black lines are superimposed on Cyan.

Note Cyan is the reference color to which all other colors are
aligned.
