    The Right Envelope

    These machines normally use a #10 standard commercial envelope with rounded-corner flaps that form a V shape. Envelopes with other kinds of flaps will not work. If you need to change the envelope, we can recommend a low-cost supplier.

    Order process, Warranty, Setup and Delivery

    When you place an order for a FD6404, we want to make sure that your jobs and the stock you use can be handled by the machine. We discuss your process in detail, make any necessary recommendations, and have you send samples of your jobs to the manufacturer. They are tested upon receipt. When approved, Formax will send you a written guarantee that the tested materials work in the machine.

    Upon payment, the FD6404 folder / inserter is sent from the factory. It normally arrives within 10-15 business days. It comes with a 90 day on-site warranty, which includes setup and training by a technician from your local area. If you have a problem during the warranty period, your local technician must be on-site within 24 hours of your call. All parts and labor are covered.

    On-Site Maintenance Agreement

    You can also purchase an annual on-site maintenance agreement that works the same way. All non-consumable parts and labor are covered, and 2 general maintenance visits per year are included. The annual cost of the agreement starts at $2560 for the base model, the 6404-Standard 2.


    If you have been in business for at least 2 years, you have the option of leasing the machine for a period of 2 to 5 years. Fair Market Value and Dollar Buyout leases are available, meaning you can buy the machine at the end of the lease for its fair market value or for $1 respectively. Approval can usually be done very quickly, normally over the phone. Please call for a quote.
