Limitations of the BLM 35/50 system, cont.
• Staple leg offset outside the 1,0mm specication can occur on thicker sets. To check if the unit
performs within specication produce a book made from 4 sheets of 80 gsm plain paper.
• For thick books with a thin cover, the cover can be “pulled back” during the registration process
in the Face Trimmer. This can result in the cover sheet not being trimmed. Recommendation is
to use a heavier cover for thick books (over approx. 15 sheets).
• For some media, the legs of the staples may not be properly clinched causing the legs of the
staple to be spaced away from the inner sheet. This phenomenon occurs on extra thick books
over 40 sheets made from “soft” paper (recycled and some non-coated media mostly).
• The BookFold roller can pick up “colour” from the rst staple during the BookFold process.
After one full revolution of the BookFold roller, the colour is smeared off on the spine of the
booklet. This phenomenon occurs more for some coated media and for higher BookFold
modes.
• The “pressure foot” in the BookFold Module can cause a shiny mark on sensitive media. This
phenomenon has been observed on Glossy media.
• Thick booklets that are not square folded may have a higher tendency to be scratched.
• Sensitive media may pick up toner or residue while being transported through the paper path.
Cleaning the paper path and conducting some preventative maintenance may help improve the
situation.
