Frequently Asked Questions
What exactly does the metal detection do?
HSM describes it as protecting the cutting unit: if metal parts such as staples are inserted, the device stops so the object can be removed before operation continues. It is an interlock, not a filter. It does not sort your paper for you, and it will stop the machine mid-stack, so it is most valuable where the input is genuinely unpredictable rather than as a substitute for basic preparation.
Does metal detection mean I cannot shred stapled paperwork?
This is the practical question buyers should ask before ordering, and we will not guess at the sensitivity threshold. HSM lists paper as the material for the paper head on this article and describes the detector as triggering on metal parts such as staples. Confirm with HSM or with us how the detector behaves with ordinary staples in your intended workflow, because a detector that halts on every staple would change how your team uses the machine.
How does it differ from article 1885121M?
Metal detection is the only functional difference. Both are P-6 at 0.78 x 11 mm with 13 to 15 sheets per pass, both carry the separate 2 x 2 mm OMDD unit at O-6 and T-6, and both use the same 330 mm throat, 145 litre bin and 1300 W drive. HSM's published weight differs between the two articles and we have flagged that with the manufacturer rather than reconcile it ourselves.
Will it destroy USB sticks?
HSM lists CDs and DVDs, credit and loyalty cards and floppy disks for the 2 x 2 mm OMDD unit on this article. USB sticks are not among the materials we can verify for this article, so do not assume it. If solid-state media destruction is a requirement, specify it separately rather than relying on a media slot designed around optical discs.
Is it NSA approved?
No. NSA/CSS 02-01 requires a maximum 1 mm x 5 mm particle and listing on the NSA Evaluated Products List. This machine cuts paper to 0.78 x 11 mm, longer than the 5 mm limit, and does not appear on the list. The P40i entry on the July 2025 EPL is the L6 (1 x 5 mm) OMDD Combi configuration.
What maintenance does it need?
Refill the automatic oiler with HSM cutting block special oil, empty the 145 litre paper container and the separate media container, and clear the intake when the metal detector trips. There is no manual roller oiling routine. The machine carries a 3-year SECURIO warranty; the lifetime cutting-roller warranty stops at P-5 and so does not apply here.
