Results Interpretation/Actions
Reports the tray status (present,
plate not lifted, etc.). See Paper
Path Status test for a description
of the configuration encoding.
Reports the highest peak during
the first quarter of the lifting
interval.
Reports the interval between
the initial power min (when the
plate is not yet engaged), and
the point where the lifting power
becomes a constant.
Reports the average power over
the center ¾ of the lifting
interval.
Reports the interval from the
motor start time until the
required lift power starts to
increase due to the initial
contact with the nudger roller
assembly.
Reports the interval from the
motor start time until plate lifted
is indicated.
Reports the average stall power
during the overlifting interval
Results Interpretation/Actions
Reports the height of the initial
peak when starting rotation of
the dm drive gear.
Reports the time since the start
of CCW motion until the peak
was detected.
