Automatically assemble up to 800,000 envelopes per month

Whether you’re processing invoices, personalized direct mail, or highly confidential financial documents into envelopes or flats, the DS-1200 G4i is the ideal solution. Frequent application changeovers or small job runs are quick and easy with a simple touch of a button. Each job is programmed using the graphical touch screen, and most job changes are completed in less time than it takes to load the materials. The simplicity of user controls ensures that set-up time is reduced to seconds rather than hours, significantly reducing the need for a dedicated operator and on-site support.
