Outline of Color Misalignment Adjustment Method
Adjustment patterns printed on a transfer belt are read using sensors that are installed inside a
sensor shutter placed under a transfer belt unit, for adjusting color misalignments. The sensor
detects the patterns for adjusting color misalignments.
Auto-Start timing for Color registration
• In power-on
• When a cover is closed after the cover is open in a short time
• When printing 400 pages or more after the previous implementation
Toner amounts on the produced patterns, contamination of the sensor with toner, problems with
opening or closing of the sensor shutter, or other reasons, a color misalignment adjustment error
may occur. No control panel display of the error is provided. In such cases, adjustments on any
color misalignments (Section 5.4.2.6) are forced to be executed by the Self-diagnostic Mode and
displayed errors must be checked.
