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 Value Actions 0 Engage -35 to 35 Reports the static difference between the Displacement (mpts) 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 0 to 25 (mpts) Reports the magnitude of the reaction of the drum to the contact of the blade. (See R2) 4 Release -5 to 5 Displacement (mpts) 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). 4-44 WorkCentre C2424 Service Manual
