Still Supported by All For Mailers

Even though this model is no longer in current production, All For Mailers still stands behind it. As a veteran-owned dealer whose people have been in the mailing and print-finishing industry since 1991, we help keep your equipment running with genuine parts, supplies, and experienced service support.

Looking to upgrade? Our current Formax 6608 Series carries this modular, high-capacity design forward with faster setup and modern feeder options — ask us for a quote.

Straight talk: some parts for the Formax FD 6604 Series are getting hard to find — but it was built to last. These were genuinely well-made units, and a well-cared-for one may run for years yet. It’s off the current price lists, and while we can still source many parts, certain components — most often boards, displays and electronics — are increasingly scarce. We can often keep one running. We just can’t promise it indefinitely.

Protect what you have. These machines were built to last, and the mechanics will outlive the electronics every time. If you’re running one, put it on a quality surge protector, and add static protection — especially in dry winter air or on high-speed paper handling. Power spikes and static are what kill boards, and on these machines a board may not be replaceable at any price. It’s the cheapest insurance there is for equipment you can’t simply reorder.

Already own one? Call 866-430-2874 before you commit to a major repair — we’ll tell you honestly whether the part exists and whether the repair is worth it. SuppliesForMailers.com still stocks consumables.

Shopping today? We’d steer you toward a current, supported platform — the Formax FD 6104, FD 6210, FD 6306, FD 6308, FD 6406 and FD 6608. Tell us your volume and piece sizes and we’ll match you to the right machine, with parts, service and lifetime phone support behind it.
