Staple mode feed and delivery

In this mode, two to fifteen pages of media are stapled into one set and the stacks are then delivered to the delivery bin.

After the leading edge of the media reaches the fixing delivery sensor (PS108) in the printer the DC controller PCA sends a signal to the stapler/stacker driver PCA. The stapler/stacker driver PCA activates the deflector solenoid (SL101) for a specific amount of time to move the delivery deflector into place, which routes the media to the stapler/stacker rather than the printer’s top output bin.

The stapler/stacker driver PCA activates the paddle motor (M1101) to rotate (counterclockwise) the upper and lower delivery rollers to disengage them. It also activates the stacker motor (which rotates at the same speed as the printer’s main motor) to rotate the feed and delivery rollers.
