Limitations in the MX-BM50 system
• The Plockmatic MX-BM50 Production Booklet Maker is suited for customers whose
booklet making needs will not exceed an average 20,000 booklets per month.
• If sheets entering the MX-BM50 are not uniform and square the booklet quality will vary
accordingly.
• The maximum recommended number of sheets that can be folded without stapling is 5
sheets of 80 gsm. If there is very low friction between the sheets, running non stapled
sets may be difficult.
• Staple position may vary on the spine when being square folded with the BookFold
MX-FD50 module, especially on thicker booklets. Moving staple position so staple is
centered on the spine will reduce this phenomenon.
• Staple may be radius shaped (bent) when running with Book Fold module. Moving sta-
ple position so staple is centered on the spine will reduce this phenomenon.
• Covers may show marking along the spine of the booklet from the clamp in the MX-
FD50 module. The more pages in the booklet, the more evident the marking. The use
of “protection sheet” eliminates this marking.
• For some white coated stock, such as “Silk type” two sided coated paper, occasional
fold roller marks may be observed on the “top side” of the book. . The use of “protection
sheet” eliminates this marking.
• Simplex booklets are not supported.
The double feed sensor should be turned off when feeding cover 200 gsm or more from
the MX-CF50 module. You may also have to turn off this function if you have heavy
dark area coverage or covers with different images on them.
• For jobs with multiple sheets of 200 gsm or heavier the MX-FD50 module is recom-
mended for an acceptable output. If MX-FD50 module is present in the configuration
the Book Fold shall be turned ON or feed problem at output may occur.
• The protection sheet function may not function correctly with thicker booklets. If there is
very low friction between the protection sheet and the set, functionality may be poor.
• Heavy weight media will show image crack in the spine, pre-crease the cover to avoid cracking.
• Thick books made from coated stock with high friction between each sheet may show
permanent “wave like” deformation of the sheets.
• Marks from the fold knife may appear on sensitive media on the inner sheet.
• Marks from side guide motion may appear on sensitive media, the use of protection
sheet eliminates this.
