Mint 310 Series Mailing System

Designed for demanding mail centers, the Mint 310 Series Mailing Systems combine high processing speeds with a user-friendly interface. The Mint 310 Series is available in two models, Mint 310 and Mint 310 Expert, both with an automatic envelope feeder that can handle mixed size mail input. Each system meets the latest USPS requirements for Intelligent Mail Indicia (IMI) and Dimensional Weighing (DIM).

Dynamic, High-Volume Mailing System

The Mint 310 processes up to 140 letters per minute (lpm), and the Mint 310 Expert handles up to 175 lpm. Each system features an integrated 10 # Differential Weighing Platform which automatically calculates the correct postage for each piece. Optional 30 and 70 lb. weighing platforms are available.

The user-friendly interface includes a large, color touchscreen with intuitive prompts and shortcut keys to eliminate extra keystrokes and increase efficiency. The Mint 310 automatically receives updates by connecting via LAN every 72 hours, keeping postage rates  up to date. In addition to postage, users can personalize mailings with ad slogans, custom text messages, QR codes or company logos. Users can store up to 9 job imprints that can be easily recalled via the touchscreen.

The Mint 310 helps manage your mailing budget with 100 standard departmental accounts, with options of up to 300 or 500 accounts. Additional standard features include an envelope moistener, an expandable catch tray to hold mail up to 10” x 13”, low-ink email alerts, and eco-friendly low energy sleep mode.

An optional Dynamic Scale weighs, measures, and classifies mail pieces on-the-fly for fast processing with less handling by the operator. With the Dynamic Scale, the Mint 310 processes up to 75 lpm, while the Mint 310 Expert processes up to 110 lpm.
