Toner Patch Sensing (TPS) is a
diagnostic mechanism that
automatically adjusts the printer
toner density and alignment
settings.
When TPS executes, the printer
generates toner patches on the
transfer belt. Then, it uses these to
calculate the appropriate amount of
adjustment, if necessary.
When an event initiates a TPS
operation, the printer performs a
toner density calibration or an
alignment calibration, or both of the
calibrations.
