3,000-sheet stapler/stacker

Main modules
The 3,000-sheet stapler/stacker consists of the following main modules:
Face-up bin
Face-down or stacker bin
Accumulator

62 Theory of operation
Face-up bin—This bin collects the documents face-up, with the printed information toward
the user. Finished documents are not routed to this bin, but the bin supports the sheets as
they are flipped to the face-down bin. This face-up bin has a capacity of 125 sheets of media
2
(75 g/m , or 20 lb).
Face-down (stacker) bin—Collated and stapled jobs are routed to the face-down (stacker)
bin. The bin has a capacity of 3,000 sheets (75 g/m
2
sheets (75 g/m , or 20 lb) of ledger/A3 paper.
Accumulator—The accumulator collects the sheets in the accumulator bed and registers a
whole job or copy. Additionally, the accumulator transports the job to the stapler module
when a stapling option is selected, and can also offset print jobs. After finishing, the
accumulator routes the print job to the face-down bin.
Stack holder—The stack holder holds the sheets that are in the face-down bin.
Flipper—The flipper module flips sheets of paper from a face-up position to a face-down
position. This function is necessary in order to accumulate the job correctly and to
accommodate staples.
Paper path—The paper-path module routes the print job after the media leaves the flipper
module if the printed media is face-down. If the media is face-up, the print job is routed
directly from the flipper module to the face-up bin.
Stapler and carriage—This module is used to staple print jobs. The stapler is mounted in a
carriage that moves from side to side. The side-to-side motion accommodates stapling in
various positions on the edge of the print job that is in the accumulator.
Controller PCA—The controller PCA controls the entire unit. All stapler/stacker-module
cables are connected to the controller PCA.
Power supply—This is the main power supply for the device. The power supply is universal,
which means that it can work with products that use from 110 Vac to 220 Vac.
