5 CCW Off fe settling
time (sec).
0.010 to
0.20
0 to .5 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.
6 Time to CW On
peak fe (sec).
0.010 to
0.06
0 to .05 Reports a time that indicates
how long it takes the MP motor
servo system to react to the
sudden addition of the deskew
shaft load. Larger values may
indicate a slipping or slow to
engage clutch.
7 CW On peak fe. -950 to
-450
-7.0 to
-2.0
Reports the peak effort required
to accelerate the deskew shaft
load. A smaller value could
indicate a slipping clutch.
8 CW On fe settling
time (sec).
0.010 to
0.20
0 to .2 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.
9 CW On average fe. -610 to
-220
-3 to 1.3 Reports the average effort
required to rotate the deskew
shaft in the CW 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).
Deskew Shaft (Continued)
Runs the media path drive train and engages the deskew clutch on the fly then disengages the
clutch. The test is repeated in both directions to determine clutch characteristics, steady state
drive requirements, bearing status, etc.
