scanning of the setup sheet.

The plotter positions the cartridge carriage over the media. The carriage remains
there for about 1 minute with the red L
calibration. The plotter then ejects the sheet.
To verify that the calibration has been performed correctly, plot a service configuration
plot, D page 8 23, and look at the field entitled Setup Sheet LED Calibration formula."
