Frequently Asked Questions
Why does the P-5 take fewer sheets than the P-4 version?
Because the cutting head has to do more work per sheet. The P-5 reduces paper to 30 mm² particles against 160 mm² for the P-4, which means far more cutting edges engaging the stack and much more resistance. From the same 0.75 HP motor you get 8 to 10 sheets instead of 12 to 14. This trade is inherent to shredders and applies across every manufacturer, not just MBM.
How many people can share this machine?
Six to ten in normal office use. The 20-gallon bin absorbs a department's daily output without frequent emptying, and the 10.25-inch throat means people can feed documents quickly without lining them up carefully. The 8 to 10 sheet capacity is the pacing constraint rather than the bin, so if several people arrive at once there will be a short queue. That is normal for any P-5 machine.
Does it shred credit cards and CDs?
Credit cards yes, optical media no. MBM lists staples, paper clips and credit cards for the cross-cut 2503 models. CDs and DVDs are rated only for the strip-cut version of this cabinet. A P-5 cutting head has fine teeth that a polycarbonate disk can chip, and shaft damage from unrated material is not something the lifetime shaft warranty is intended to cover.
How often will the 20-gallon bin need emptying?
Less often than any deskside P-5 machine, but more often than the sheet count implies. P-5 confetti is fine and traps a lot of air, so it occupies more volume per sheet destroyed than P-4 waste. MBM does not publish a sheets-per-fill figure for the 2503, so we will not quote one. For a department of eight, plan on emptying it once or twice a week. The machine cuts power automatically when the bin registers full.
Is P-5 required, or would P-4 do?
It depends entirely on what you have committed to. No US regulation names a DIN 66399 level; HIPAA, FACTA and GDPR all require destruction that makes information unreadable and unreconstructable and leave the method to you. P-4 is the common commercial standard. P-5 is what organisations adopt when a client contract or an internal policy specifies it, or when the material is directly identifying and the consequence of exposure is serious. Read your own policy before paying for the finer cut.
Will it fit through a standard doorway?
Yes. The cabinet is 14.75 inches deep, 19.75 inches wide and 34.25 inches tall, which passes through any standard 30-inch or wider door upright. At 78 lb it is a two-person lift or a one-person job with a dolly. It is a floor-standing unit rather than a deskside one, so plan a permanent position for it near the printers or the file room rather than under a desk.
