Reports the average effort
needed to rotate the tray 2 pick
shaft in the pick direction at a
constant velocity. An unusual
value could indicate a binding
shaft, missing pressure springs,
hard/dirty rollers, extra friction in
the pick truck assembly.
Reports the variation of effort
required to rotate the tray 2 pick
shaft in the pick direction at a
constant velocity. A larger value
could indicate particles in the
gears or non uniform
contamination of a roller
(causing a lump).
Reports the time it takes the MP
motor servo system to "settle
down" after the sudden release
of the tray 2 pick shaft load.
A larger value could indicate a
dragging or slow to release
clutch.
Reports the time between the
activation of the tray 2 lift motor
and the detection of the raised
lift plate. Out of range values
may indicate a problem with the
lifting mechanism (which could
effect the following friction
measurement), or media left in
the tray.
Reports the peak effort required
to drive the pick shaft when the
nudger roller is in contact with
the separator pad.
A smaller value could indicate a
slipping clutch, missing nudger
assembly pressure spring, or
glazed/dirty roller/pad.
