Frequently Asked Questions
Is a 400 mm feed opening actually useful, or is it marketing?
It is useful in two situations. First, when a machine is shared and people feed loose handfuls rather than neat stacks - a wide throat tolerates that. Second, when you shred anything wider than letter or A4, such as tabloid printouts, wide fanfold stationery or folded plans. If you only ever shred neat letter-size stacks, the 310 mm throat on the Pure 630 does the same job.
How does P-2 compare to P-4 in practice?
DIN 66399 caps P-2 at 800 mm2 of particle area and P-4 at 160 mm2 - a factor of five. A 5.8 mm strip runs the full length of the page, so a determined reconstruction of a P-2 output is tedious but demonstrably possible. P-4 particles are 4.5 x 30 mm fragments that carry a few characters each. Choose on the sensitivity of the paper, not on speed.
Will tabloid or ledger paper fit?
Yes. Ledger is 279 mm wide and A3 is 297 mm, so both fit inside the 400 mm opening fed portrait, without folding. US letter and legal are 216 mm and pose no difficulty at all. That 400 mm figure is the main practical advantage of this chassis over the Pure 630's 310 mm, and it also means wide fanfold and continuous stationery go straight in. Anything wider than 400 mm still has to be folded or torn.
How often will the bin fill?
HSM rates the 145 litre bin at about 1,085 shredded sheets in this strip cut. Strip waste is bulky, so a mailroom pushing several hundred pages a day will be emptying it every day or two. If bin changes are the bottleneck, the Pure 740 max carries 240 litres.
Does it need a cool-down period?
No. The Pure 740 is built for continuous operation rather than the intermittent duty cycles quoted on consumer shredders. Sustained shredding is within its design envelope; the machine will stop for an overloaded feed or a full bin, which is normal behaviour, not thermal protection.
Can I put a whole ring binder through it?
No. Remove the binder mechanism first. The rollers are rated for staples and paper clips, not for ring binder hardware, plastic combs or bulldog clips. Feeding those is one of the few ways to damage a head that otherwise carries a lifetime warranty.
