DPI Hawk M7 4.25" Inkjet: Self-Mailer Addressing at 900 FPM
Product Details
The DPI Hawk M7 doesn't slow down for odd formats. This video shows a 4.25" Hawk M7 addressing unique self-mailers at 900 feet per minute — variable names, addresses, and USPS barcodes landing cleanly on non-standard mail pieces at a line speed most addressing systems never touch.
What this video shows: A Hawk M7 in its 4.25" configuration running self-mailers through the transport at 900 FPM, imaging variable data piece to piece. Watch the print quality hold at speed — crisp addresses and readable barcodes on a folded, non-standard format, with no slowdown between pieces.
Who runs the Hawk M7 this way: Direct mail houses producing self-mailers, folded pieces, and other unique formats that can't run through envelope-only addressing equipment. Lettershops that bid high-volume jobs on turnaround — where the difference between 300 and 900 FPM is the difference between one shift and three. Operations consolidating addressing onto one platform that handles envelopes, self-mailers, and flats alike.
Why the Hawk M7 for odd-format mail: Self-mailers and unique pieces are where rigid addressing systems struggle — inconsistent thickness, folds, and surfaces that smear or skew. The M7's Kyocera printheads and adjustable drop sizing keep addresses and IMb barcodes crisp on varied stock, and its speed range means the odd formats run just as fast as the standard work. One machine, every format, full production speed.

Frequently asked
How is the Hawk M7 running 900 FPM when the spec says 500?
The M7's down-web resolution is adjustable from 300 to 1200 dpi. At 600 dpi it rates up to 500 FPM; dialing the down-web resolution for the job — as in this demo — lets the transport run substantially faster while keeping addresses and barcodes fully readable.
Can the Hawk M7 address self-mailers and odd-size pieces, not just envelopes?
Yes — that's exactly what this video shows. The M7 images variable data on self-mailers, folded pieces, postcards, and flats, holding print quality across varied thickness and stock.
Do USPS barcodes stay readable at these speeds?
Yes. The M7's adjustable 7–14 pl drop sizing and bar-shaving are tuned for IMb readability, so pieces printed at full line speed still qualify for USPS Automation rates.
