110 Theory of operation Q2431-90912
The jogger guide motor (M1101) moves the jogger guides to the waiting position, and the stapler/
stacker driver PCA again activates the paddle motor (M1101) counterclockwise to engage the
upper and lower delivery rollers.

At a specific time after the paper inlet sensor (PS1101) detects the leading edge of the media,
the stapler/stacker PCA changes the speed of the feed motor (M1103) to synchronize the feed
rollers with the speeds of the other stapler/stacker motors and rollers. The stapler/stacker PCA
then activates the paddle motor (M1101) counterclockwise to again disengage the upper and
lower delivery rollers. The delivery deflector returns to its normal position.
