Letter openers, from a desk to a mail center

Designed for small and medium operations opening 200 to 2,000 pieces a day, the LO-210 is a compact tabletop unit. Milling technology produces a smooth, feathered edge and opens envelopes edge to edge for easy extraction, and the chips go to a large bin so the work area stays clear.

The LO-410 opens mail of mixed sizes and thicknesses at up to 400 envelopes a minute and can print receipt information on each envelope. The large 5.5-inch display gives simple navigation to job functions; with the integrated inkjet printer it counts mail as it is processed, or imprints the time and date.

Milling technology prevents cut contents and produces a smooth, soft, feathered edge, and the chip tray holds the waste from 3,500 envelopes before it needs emptying.

The LO-440's large input hopper has three belts that adjust to different envelope sizes on the fly, so you do not presort. Stack everything together, tap one edge to push the contents away from the cutting side, and load the batch. It handles envelopes up to 10 by 14 inches and 3/8 inch thick, which covers most flats and overnight envelopes.

Dual hardened high-speed-steel blades resist nicks from clips and staples, cut the full length of the envelope and sharpen themselves. The cutting width is adjustable, so the contents are not damaged.

The Postmark 3056 removes up to 3 mm of the envelope edge with a milling cutter and deposits the chips in a waste bin. A mixed-thickness separator passes one envelope at a time for cleaner cuts. It opens mixed mail from the smallest to the largest, flats included, up to 6 mm thick.

Solid metal construction throughout, made of steel, with two motors for performance and a longer life.

The 3068 opens up to 32,000 envelopes an hour theoretically, 10,000 in production, with the same milling cutter and mixed-thickness separator as the 3056, in a floor-standing unit with the stand and waste bin included.

Resettable, batch, rate and lifetime counters; on-demand and delayed feeding; the cutter switches off for counting; and the speed is variable. An optional 12 mm print head prints the date, time or a bitmap on each envelope.

The 3078 is the fastest Postmark opener: 36,000 envelopes an hour theoretical, 20,000 in production. A reverse-flow conveyor brings the opened envelopes back to the operator, who feeds and unloads from one spot, which raises production by about 40 percent.

The 306 has the speed and features for high-volume incoming mail centers: 40,000 pieces an hour, including large flats and overnights up to half an inch thick. Milling cutting leaves safe, soft-feathered edges and protects the contents.

The 306s sorter option separates opened mail into two output paths by programmable length, width or thickness, so clean and exception mail are grouped before distribution.
