4-20 WorkCentre C2424 Service Manual
1
CCW On peak fe. 25 to 100 Reports the peak effort required to accelerate
the wiper shaft load. A smaller value could
indicate a slipping clutch.
2
CCW On fe settling
time (sec). -2.1 to
0.25 Reports the time it takes the MP motor servo
system to "settle down" following the sudden
addition of the wiper shaft load.
A longer time could indicate a looseness in the
wiper shaft assembly or a slipping clutch.
3
CCW On average fe. 10 to 50 Reports the average effort required to rotate
the wiper 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).
4
CCW On fe ripple. 25 to 100 Reports the variation of effort needed to rotate
the wiper 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).
5
CCW Off fe setting
time (sec). 0.01to
0.20 Reports the time it takes the MP motor servo
system to “settle down” after the sudden
release of the wiper shaft load. A larger value
may show a dragging or slow to release clutch.
6
Time to CW On
peak fe (sec). 0.005 to
0.20 Reports how long it takes the MP motor servo
system to react to the sudden addition of the
wiper shaft load.
Larger values may indicate a slipping or slow to
engage clutch.
7
CW On peak fe. -275 to
-10
Reports the peak effort required to accelerate
the wiper shaft load.
A smaller value could indicate a slipping clutch.
8
CW On fe settling
time (sec).
0.01 to
0.20
Reports the time it takes the MP motor servo
system to "settle down" following the sudden
addition of the wiper shaft load.
A longer time could indicate a looseness in the
wiper shaft assembly or a slipping clutch.
Wiper Shaft (Continued)
Runs the media path drive train and engages the head maintenance 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.
