306 Automatic Letter Opener


The 306 offers the speed and features needed in high volume incoming mail centers. Able to open 100 letters in under 10 seconds (40,000 pieces per hour), this machine will make quick work of all your envelopes, including large flats and overnights up to ½” thick.

Milling cutting means your opened mail has safe, soft-feathered edges, while preventing damage to envelope contents.

The enhanced sorter option (Model 306s) adds the ability to separate opened mail into two different output paths based on programmable length, width and/or thickness. This lets you group “clean” and “exception” mail before distributing to recipients.

The 306s is the world’s fastest envelope opener/sorter, making it the appropriate automation solution for mail centers with large volumes of inbound mail.

Standard Features

High Speed for High-Volume Incoming Mail: The 306 blasts through envelopes so fast, you may have trouble keeping the feeder full. At up to 40,000 envelopes/hour, this satisfies the needs of most large volume mail centers.

Advanced Cutting Technology: The milling cutter has eight cut-depth positions, and is able to cut to depths as small as 1/10 inch, preventing damage to envelope contents. The cutter makes soft, feathered edges on the envelope openings, which guards against paper cuts, and generates waste as tiny paper chips. It includes a “no-cut” position for envelope counting modes.

Control Panel: The 306 comes with a user-friendly control panel and sharp LCD display with integrated software that makes setting flexible job criteria easy. It supports multiple users with password security.

Retractable, Ergonomic Mail Tray Holders: Operators will appreciate the integrated slide-out mail tray holders that position input and output bins right where they’re needed.

Optional Features

Sorting: The optional sorter (Model 306s) allows mail separation based on pre-configurable criteria, including envelope height or length or thickness—for example, separating “clean” reply mail of specific dimensions from other “exception” mail. Applications include claims processing, remittance, and mail voting. The 306s can also run in “sort only” mode, which separates mail, but does not open it.

Batching separates the mail into batches based on piece counts.

Output Conveyor: The 90° conveyor gives the 306s model expanded output capacity for extending uninterrupted runs.

Reports Printer: Optional report printing lets you print hard copies of processing statistics, which is important for environments like election voting where every step needs an audit trail.

Integrated Envelope Printer: Adding the high-speed printer lets you add text to envelopes during processing. For example, date/time stamps, barcodes, department number OR sequence codes. This is useful for industries and applications like insurance, elections, invoice payments, and government agencies.
