During automatic line position adjustment, the line patterns below are created eight times on the transfer belt. The spaces

between the lines (KK, CC, MM, YY, KC, KM, KY) are measured by the front, center, and rear ID sensors. The controller

takes the average of the spaces, then adjusts the following positions and magnification :

Sub scan line position for CMY

Main scan line position for CMY

Magnification ratio for CMY

Skew for CMY

The transfer belt-cleaning unit cleans the transfer belt after the patterns are measured.

KK, CC, MM, YY: Spaces between two lines of the same color.

KC, KM, KY: Spaces between a black line and each color line.
