• In the event of a jam in the finisher, it may be necessary to discard waste sheets of partial chunks that
have collected in the compiling station. This is kept to a minimum, and is only necessary in a limited
number of conditions.
• The maximum chunk size can be modified to meet workflow needs; lowering it reduces potential job
recovery waste but increases the number of chunk boundaries, thus affecting stack appearance.
• Small set sizes, whether offset or not, require skipped pitches to be inserted to enable the unloading of
the compiling station onto the stack below. If the set/subset size is less than 4 sheets in a 144 PPM

, or less than 3 sheets in a 120/100 PPM Nuvera

, the system will not achieve full rated speed.
• The BFM can offset between sets, and even within sets (subset offsetting), responding to embedded
“jog” or “offset” commands in the print data stream.
• The BFM supports the use of ‘jam offset sheets’ for identifying where jam interrupts have occurred.
• Since the BFM uses a compiling station, care must be taken to follow job recovery instructions displayed
on the GUI so as to avoid mixing unusable output with good output, and risking delivery of duplicate
output.
• Requests to unload the stacker (via the door button or the GUI) are honored at the next set or chunk
boundary reached, which could be as high as 100 sheets plus 25 sheets of in-process scheduled pages
after the time the unload was requested.
• Any unload (initiated by the operator or due to stack full) will result in a switch to an alternate available
BFM stacker if present

Note: The speeds indicated in the table below are the maximum attainable speeds under normal conditions of
use, when delivered to the top tray. Delivery to the main stacker can achieve equivalent speeds, except for
those paper sizes (as are noted below with an *) for which sheets are not buffered in the BFM compiler
transport between sets. Those papers require up to 4 skips between sets, and that needs to be factored into
performance expectations.
