Stripper Contact
This test holds the drum stationary while the stripper solenoid is activated and released. The
drum servo error signal illustrates activation/deactivation timing and how strongly the drum was
contacted by the blade.
R# Definition
Typical

Actions
0
Engage
Displacement (mpts) -35 to 35 Reports the static difference between the
average ya_fe before and after the blade
contacts the drum, indicating how strongly the
blade is interacting with the drum while
pushing onto the drum.
May be an indication as to the condition of the
blade (stiffness, dirty, bent, delaminated, etc.).
Another potential factor could be the solenoid
range of travel or engagement force (solenoid/
solenoid drive strength or return spring
strength).
1
Engage Time (sec) 0 to 0.054 Reports time between engagement of the
stripper solenoid and initial contact between
the blade and the drum.
May indicate the geometry of the mechanism
(i.e. parts out of tolerance, mis-assembled,
bent, etc.), causing an incorrect blade to drum
gap.
2
Engaging Period
(sec) 0 to 0.11 Reports time between stripper solenoid
engagement and the point when the reaction of
the drum to the contact of the blade fades back
into the ripple (noise). Another indication of
blade to drum interaction. The profile shape
(R2/R2) could be a dynamic indication of the
blade/drum interaction as is the static value
reported by R0.
3
Engaging Amplitude
(mpts) 0 to 25 Reports the magnitude of the reaction of the
drum to the contact of the blade. (See R2)
4
Release
Displacement (mpts) -5 to 5 Reports the static difference between the
average ya_fe before and after the blade
disengages from the drum, indicating the
strength of the blade/drum interaction while
pulling off the drum. (See R0).
5
Release Time (sec) 0 to 0.09 Reports the time between the disengagement
of the stripper sol and the point when the blade
begins to withdraw from the drum (see R2).
6
Releasing Period
(sec) -1 to 1 Reports the time between the disengagement
of the stripper sol and the point when the
reaction of the drum to the withdrawal of the
blade fades back into the ripple (see R2).
