2.13 Color Drift Detection
The Z71-PCB reflective optical sensor detects color drift. There is one each on the left and right
side in front of the cleaning blade behind the belt unit. A color drift detection pattern is printed
on both ends of the left and right side of the belt. Then the reflective optical sensor reads this
detection pattern to measure the drift level based on black as a standard. The correction value is
then determined based on this measurement. Then the main scanning, sub-scanning, and skewed
color drift correction automatically takes place.
This detection takes place when the power is turned ON, cover is closed, the printer is left un-
used for 2 hours or longer, and every time after printing 400 sheets.
