100/120/144 EA Digital Production System - Customer Expectations Document

Output
• Paper sizes supported to the main tray (stapled and unstapled):
Process direction - 7.0 to 18.5 in. (178 mm to 470 mm)
Cross Process direction - 8.0 to 12 in. (203 mm to 305 mm)
• Smaller sizes (down to A5 and Statement) or larger sizes (including SRA3) can be run to the top tray.
• Mixed sized output allows stacking of different size pages, both in the process and cross-process
direction, in a single job.
• When stapling sets with mixed size stock, the stock must be the same dimension in the Across Feed
direction, and the dimension differences should be within 13mm (½”) in the feed direction.
• To have the BFM staple correctly, the output must be 1-N facedown.
• Envelopes can only be sent open flap trailing to the Top Tray, and should be limited to 15, or mis-
stacking may occur.
• The BFM / BFM Plus does not offset paper sizes larger than 11”x17" / A3. This means that 12”x18” or
12x18.5” cannot be offset. For these sizes, the software ignores any offset programming selection, and
runs without offsetting.
• Banner and slip sheets should be greater than or equal to 90 gsm (24 lb bond)
• Slip-sheets must be the same size as the body sheets
• Stapler capacity is reduced for coated papers and paper heavier than 20 lb. bond (75 gsm).
• For reliable stacking, stack size should be limited for certain jobs:
--Offset single sheet jobs should be limited to 100 sheets. (20 lb bond or 75 gsm)
--Stapled sets of 15 sheets or smaller are limited by machine control to 100 sets.
--Stapled sets of coated stocks stack less well, and should be managed to 50 by the operator.
--Stapled sets should be offset stacked.
--The stack height limitation can be operator adjusted.
• Automatic bin limits control the number of sheets collected and compiled in the finisher when running
unfinished sets to optimize the set drop performance and improve job recovery.
Tabs
The tabs cross process length must be the same as the body of the document. The tab can be no longer
than 0.5” (13mm) in the process direction beyond the body of the document. Tabs sized for use with 8.5” x
11” and A4 stock, long edge feed, are supported
Transparencies
Transparencies run to the stacker must have a slip-sheet between each one.
Stapling
• The BFM is delivered with a 5000 staple cartridge of 100-sheet staples installed in each of the two
staplers.
• Staples for up to 30 sheets and for up to 100 sheets are available. Stapled jobs over 100 sheets are
inhibited. The machine does not detect staple size. The operator must manage jobs to be within
capability of the loaded staple size.
• Some marking of the staple onto an adjacent set may be seen.
• Not all stapler failure modes are detected by the machine logic. The customer may find some
occurrence of unstapled sets in the output.
Carbonless
• In the DPS BFM configuration, curl that faces up poses more of a problem than curl that faces down.
To avoid up curl, 2, 3 and 4 part Carbonless should be run to the BFM in an N to1 mode and use
reverse collated versions of the recommended Xerox media. See compatible media tables in this
document.
Additional notes related to DocuPrint migration
The BFM is a set-level device. It is designed to collect sheets into set-sized chunks (using the compiling
station), optionally staple and/or offset the chunks, and then place those on to the stack below. It can reliably
stack unfinished output, and it supports unloading and auto-switching to another available BFM Stacker;
however, the following should be noted:
• Since it is a set-level device, boundaries between chunks in a stack may be visible.
