Process Control Summary
What is done?
The machine calibrates the TM sensors
The machine makes a 9-grade pattern on the
belt, and the central TM sensor scans these
patterns.
The machine can then calculate the correct
development bias and laser diode power.
MUSIC: The machine then checks for color
registration errors. To do this it makes lines at the
left, center, and right of the transfer belt and
scans these lines with the TM sensors.
