Operating Manual Introduction
Thank You
Thank you for purchasing the MBM 256 LS “Light Set” document folder.
Properly used and maintained, this machine will provide many years of
reliable service.
Description
The 256 LS imparts both standard and custom folds to cut-sheet documents from 3.25" x 5" (A6) up to 11" x 17" (A3).
Fold type and dimensions are set using the scales on the top tables and documents to be folded are stacked between guides on the feed table. The feed rolls
take the top sheet from the stack and feed it into the folding process. Finished
documents exit the folding process and are neatly stacked on the exit conveyor.
Product Features
The 256 LS incorporates advanced features for ease of operation, office
friendliness and reliability.
• Variable operating speed.
• Standard folds easily set with fold knob, paper size knob, and guide lights.
• Large, 400 sheet, document capacity.
• Top feed system takes a square stack of documents – no fanning needed.
• Fold tables are arranged in a “V” pattern for easy operator access and visibility.
• Quick, flip-slide-snap macro adjustments for paper stops in the center of
the fold tables.
• Convenient micro adjustment knobs for paper stops at the top ends of the
fold tables.
• Easy paper thickness and skew adjustments.
• Out-feed stacking rollers at the exit conveyor self-set for standard folds.
They can also be adjusted for custom folds.
• Powered exit conveyor provides neat stacking.
• Extended exit tray accumulates a large output.
• Insulated for noise reduction.
• Heavy gauge steel chassis for an extremely strong machine assuring perfect alignment.
• Split style fold tables allow easy maintenance by removal of only the top
portion of the tables – easy, light and free of power connections.
• Removable top roller for easy access and cleaning.

legal size sheets into business envelopes. This fold cannot be
made in sheets smaller than legal size.
EXIT END
The left end of the folding machine where the folded documents
exit the machine.
FEED END
The right end of the folding machine where the flat documents
are placed to enter the folding process.
FOLD TABLE

Any of the five folds for which icons are shown on the fold table
scales when made in standard (8.5" x 11", 8.5" x 14" & 11" x
17") size sheets. Those five folds become custom folds when
made in other sheet sizes as do variations of the five folds in any
size sheet.

machine.
ZIG-ZAG FOLD
A fold that divides the sheet into three panels with the front of the
top part of the sheet facing out and the front of the bottom part

or accordion fold.)
