Color Registration Procedure
When first installing the machine or moving it to a new location, color drift during printing may occur. Use this function to
correct the color position of each of cyan, magenta and yellow to resolve color drift.
Auto registration and manual registration are available for Color Registration. Color drift can be largely corrected through
auto registration. However, if it is not resolved or to perform more detailed settings, use the manual registration.

once, however, it may cause the serious color drift later.
