Reports how long it takes the
MP motor servo system to react
to the sudden addition of the
deskew shaft load.
Larger values may show a
slipping/slow to engage clutch.
Reports peak effort needed to
accelerate the deskew shaft
load. A smaller value could
indicate a slipping clutch.
Reports the time it takes the MP
motor servo system to "settle
down" after the sudden addition
of the deskew shaft load.
A longer time could indicate a
looseness in the deskew shaft
assembly or a slipping clutch.
Reports the average effort
required to rotate the deskew
shaft in the CCW direction at a
constant velocity.
An unusual value could indicate
a difference in the composition
and/or number of the rollers, the
nip pressure, or out of range
mechanical dimensions due to
wear or contamination (such as
paper dust increasing the
effective diameter of a roller).
Reports the variation of effort
required to rotate the deskew
shaft in the CCW 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 deskew shaft load.
A larger value can indicate a
slow to release or dragging
clutch.
