11 Bottom Encounter
Distance (uin)
-2500 to
-1800
-4250 to -
3900
Reports the distance up from the
upper limit of travel at which the
wiper first encounters the lower
travel limit.
12 Turnaround
Recovery time (sec)
0.001 to
0.250
-0.05 to
.35
Reports the time following the
start of the turnaround motion
that the motion drive error return
to normal in the opposite
direction.
Paper Path Drive
This test moves the gear train in one direction while capturing data, does a reversal to capture
reversal transient data, then operates in the other direction.

level in the foreword direction.
1 Up Motion Drive
Error Ripple (watts)
0 to 1.5 Reports the average drive ripple
level in the forward direction.
2 Reverse Drive
Power Level (watts)
-4.0 to
-1.0
Reports the average power in the
reverse direction.
3 Down Motion Drive
Error Ripple (watts)
0 to 1.5 Reports the average drive ripple

4 Swing Arm
Transition Time (sec)
.03 to .06 Reports the time that the lower
portion of the paper path drive is
disconnected while the swing
arm transitions to the other drive
position.
Wiper Drive (Continued)
This test moves the wiper drive mechanism through the complete range of its motion in each
direction and does an “on the fly” reversal to verify operability.
