AP4 high-volume in-line digital address printer
The Formax AP4 is an in-line digital address printer for production mail. It runs up to 26,000 #10 envelopes or 34,000 postcards per hour at resolutions up to 600 x 600 DPI.
The print head is a 2 pen plus 4 pen plus 2 pen stitched design with a 4" H x 50" L imaging area, so the address, return address, indicia, and taglines all print in one pass. It runs on an in-line transport deck, stores up to 16GB of jobs, monitors ink level on screen, and takes pieces up to 1/2" thick. That combination is what puts it in busy mailrooms, commercial printers, and lettershops.

AP4 vs AP4F: which model fits
The Formax AP4 on this page runs up to 26,000 #10 envelopes per hour as an inline digital address printer, priced at $23,195. The AP4F is the companion model that adds an integrated friction feeder for standalone high-volume feeding, so it suits shops running address jobs off-line rather than in an inline finishing setup.
If you feed envelopes from an existing inline system, the AP4 is the right fit. If you need built-in feeding for standalone runs, ask us to compare the AP4F throughput tier and pricing before you order.
