Staple Finisher Compiler Section - Lexmark MS911 Service Manual

Exit section paper path for standard print jobs
The motor (staple finisher upper exit) rotates the exit guide lift cams causing the cams to release the eject guides. The
guides swing down due to their weight, and then divert the paper between the upper and lower exit rollers. The motor
(staple finisher upper exit) lowers the upper exit roller to come into contact with the paper. The upper exit roller solenoid
connects the lower exit roller to the motor (staple finisher exit). The motor drives the upper and lower exit rollers to
feed the paper to the bin.
The paper passing through the exit rollers lowers the tamper paper present sensor actuator. As the trailing edge passes
through the roller, the actuator returns to its original position, signaling that the paper is in the bin. The upper exit
roller returns to its home position.

Staple finisher compiler section parts
At the compiler section, the sheets of paper are aligned for offset and staple jobs. The sheets are individually fed and
aligned in the compiler assembly, and then fed out to the exit section.
