The stacker consists of the following main modules:
Face-up bin
Output bin
Offset module

66 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 sheets as they
are flipped to the face-down bin. This face-up bin has a capacity of 125 sheets of media (75
2
g/m , or 20 lb).
Face-down (stacker) bin—The face-down bin can collect print jobs with or without offset. The
bin has a capacity of 3,000 sheets (75 g/m
2
m , or 20 lb) of ledger paper.
Offset module—The offset module offsets print requests on a job-by-job basis as the print
job is transported to the stacker 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 route the jobs to the stacker bin correctly.
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.
Controller PCA—The controller PCA controls the entire unit. All 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 110 Vac to 220 Vac.
