Identifying the output bins
The device has two output locations: the stacker bin and the booklet
bin.
The default stacker bin (bin 1) provides 1,000 sheets of stacking
capacity and delivers documents face up or face down, depending on
which option is selected in the driver.
The booklet bin (bin 2) provides folding and saddle stitching for 40
booklets composed of up to 5 sheets (20 finished pages) of paper. A
stacking guide automatically adjusts to accommodate the size of the
booklet in production.
The stapler serves both bins, and staples as many as 50 sheets of
paper per document or 10 pages per saddle-stitched document.
A sensor causes the printer to stop when the device bins are full.
Operation continues when you remove all media from the bin.
Note Transparencies, envelopes, labels, prepunched paper and cut-sheet
paper are supported in the stacker bin (bin 1).
Note If you print envelopes, remove all envelopes from the bin once the job
is complete to maintain stacking quality.
