The Intimus TSI-4S Medium-Volume 2 Feed Station Folder-Inserter is a versatile, medium-volume desktop mail processing system engineered to automate and streamline the tasks of folding, collating, and inserting mail for offices and mailrooms that handle a range of correspondence types. As part of the TSI-4S family, this configuration adds a second FlexFeed® sheet feeder (alongside the standard insert feeder) to provide greater flexibility in handling multi-document mailings such as invoices with inserts, marketing letters, and transactional packets. With an intuitive 7″ color touchscreen and Load’n’Go® automatic setup, operators can quickly configure jobs, recall stored programs, and minimize training time – making it accessible for daily use even for non-technical users.

Designed for productivity, the system can process up to 2,500 envelopes per hour with the optional premium upgrade, and supports a wide variety of fold types including letter (C-fold), Z-fold, single, double parallel, and no fold, accommodating diverse mailing requirements. The FlexFeed® multi-format feeders handle a broad range of paper sizes and weights, while optional CIS scanning and secure’n’Feed double detection enhance mail integrity and reduce errors. Its compact footprint, quiet operation, and expandability with additional output options (like side exit or high-capacity vertical stacker) make the TSI-4S 2 Feed Station Folder-Inserter a reliable choice for offices aiming to boost efficiency and consistency in in-house mail production.
