Frequently Asked Questions
Is 2 x 15 mm really P-5 and not P-6?
Yes, P-5. The particle area is 30 mm², exactly at the P-5 ceiling of 30 mm². P-6 requires 10 mm² or less with a particle width of 1 mm or less, which a 2 mm wide cut cannot meet regardless of its length. Anyone describing a 2 x 15 mm cut as P-6 has the standard wrong.
Why does capacity drop so much versus the P-4 model?
The cutters are making about five times as many cuts per sheet. Same 1 HP motor, much finer geometry, so the sheet count has to fall — 14 to 17 sheets against 22 to 25, both measured on 70 gsm paper. If that gap is going to hurt, either accept P-4 or move up to the 3105, which uses a 2.125 HP motor to hold 24 to 26 sheets at the same P-5 cut size.
Can it shred CDs, DVDs or ID badges?
No for optical media. MBM confirms only the strip-cut and 4 x 40 mm cross-cut 3104 models for CDs and DVDs; this 2 x 15 mm build is not on that list. Credit cards and similar PVC cards are fine, as are staples and paper clips. If you need to destroy discs and P-5 paper on the same machine, this pairing is not available in the 3104 and you should look at a separate media shredder.
Does P-5 satisfy HIPAA or GLBA?
Both regulations require that protected information be rendered unreadable and unreconstructable rather than naming a DIN level, so P-4 is normally accepted and P-5 exceeds the usual bar comfortably. Where P-5 becomes worth specifying is when a client contract, a state agency requirement or an internal risk assessment names it. Check the wording that binds you before paying for a security level you do not need.
What maintenance does it need?
Very little. There is no oiler and no oil to buy, no bags required, and the shafts are covered by MBM’s lifetime warranty on this cut type. Practical maintenance amounts to emptying the 32-gallon bin, keeping paper clips out of the bin area, and not forcing more than the ECC indicator says the cutters will take.
Will it take legal-size and tabloid paper?
Yes. The 12-inch feed opening accepts letter, A4 and legal in normal orientation, and tabloid at 11 inches wide also passes. Remember that wider sheets consume more of the cutters’ capacity, so a stack of tabloid will hit the limit at fewer sheets than the quoted 14 to 17.
