PROCESS CONTROL August 2006
6-78
During process control, the creation of the patterns is timed so the Magenta, Cyan
and Yellow patterns are transferred to the ITB at approximately the same time. The
color ID sensor then reads the color ID sensor patterns in the order M, C, Y.
Note that the K pattern is read by the black ID sensor at approximately the same
time the Cyan pattern is being read.
These ID sensors read the following patterns from the ITB:
• 10-grade patterns (x4) during process control
• 16-grade patterns (x4) during process control gamma correction
• ID sensor patterns (x4) at 10 page (and other intervals) for toner supply control
