Formax FD 6104 Series Inserter

The User-Friendly Low-Volume Mailing Solution

The FD 6104 inserter offers the latest technology in entry-level tabletop inserters, making it possible for any size company to enjoy the benefits of automated folding and inserting. The affordability of this inserter eliminates the need to send out tens of thousands of mail pieces in order to justify the cost of automation.

The 5” full-color touchscreen control panel features wizard-based software which guides operators through setup and operation. It provides quick access to saved jobs, right on the home screen, while bold icons indicate the status of each feeder. Users can program up to 15 jobs for instant, one-touch operation.

With two fully-automatic sheet feeders and one automatic insert/BRE feeder, it offers a range of folding and inserting capabilities. It processes documents up to 14” in length, producing up to 1,350 envelopes per hour. Electromagnetic double document detection ensures each envelope contains the correct number of documents. The energy-saving mode automatically puts the inserter into standby after one hour of being idle.

An optional Fold-only C-Fold Kit is available for those who need to produce C-folded documents without inserting into an envelope, ideal for brochures and marketing pieces. The kit is easily installed without tools, simply by swapping out the moistener kit.

Don’t waste any more valuable time and money manually folding and inserting. Automate your mailings with the FD 6104 and maximize your company’s efficiency.

            Great product

            The safe is great! It was a gift and he loves it. There were emails communicating the shipping process all the way through. Very smooth and professional service.

            Perfect safe and great service for our needs.

            This safe is perfect for our needs.
            1. Keep items safe from little ones.
            2. Prevent little ones from trying to open.
            3. Keep documents safe in event of fire. (Fire station is only 2min away)
            4. Keep items safe from bad actor's.
            5. Price to performance ratio. (aka. doesn't break the bank).

            The service and price were excellent from armadillo. A bit shy on wanting to buy a safe online but it was easy and outstanding. Would buy from again!
