Stripper Contact (Continued)
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.

-12.3 to Reports the magnitude of the reaction of the
5.85 drum to the blade withdrawal (see R3).
Typical
Value Actions
MFG Reports the distance the pm motor was moved
Only (raising the dm unit), before a Y-axis reaction
was detected. Shows that the dm is raising,
provides blade/drum gap information.
Typical
Value Actions
0.08 to Reports amount of variation of the motor
0.6 following error over the recording interval.
0.3 to 0.8 Reports the motor following error average
value of the recording interval.
0.34 to Reports amount of variation of the motor drive
1.3 voltage over the recording interval.
-.75 to Reports average value of motor drive voltage
-1.5 over the recording interval.
0.25 to Reports variation of motor drive power over the
1.8 recording interval.
0.5 to 3.0 Reports average value of motor drive power
over the recording interval.
