This is a new Martin Yale 7400 for sale from Postroom-online – one of the UK’s largest Martin Yale dealers. The 7400 is a compact desktop paper folding machine that automatically feeds and folds up to 4,000 sheets per hour. It handles A4 and legal size paper from 60 to 105 gsm, produces four standard fold types, and comes with a catch basket for neat collection. If you need a reliable auto-folder for a small office, mailroom, church, school, or club, the Martin Yale 7400 has been one of the most popular desktop folders on the market since it launched.
How the Martin Yale 7400 Works
You load up to 50 sheets into the feed tray, set your fold type using the clearly marked guides on two removable fold plates, press the green button, and the 7400 runs through the stack unattended at approximately 66 sheets per minute. When the hopper’s empty, it shuts itself off automatically — no need to stand over it waiting for the job to finish.
It produces four standard folds: letter fold (C-fold), half fold, Z-fold, and double parallel fold. The fold plates have ruler markings so you can hit the standard positions quickly or dial in custom fold points if your job calls for something non-standard.
There’s also a manual bypass slot on top of the machine for hand-feeding up to three sheets at a time — including stapled sets. That’s useful when you’ve got a cover letter stapled to an enclosure and need them folded together as one piece, or when you’re running a short batch that doesn’t warrant loading the hopper.
Paper Compatibility
The Martin Yale 7400 accepts paper from 60 to 105 gsm across A4 and legal sizes. That range covers standard 80 gsm office copy paper, lightweight 60 gsm sheets, and heavier 100+ gsm letterheads and brochures. It uses a friction feed system with a single 50 mm feed tyre to pull sheets from the stack, which keeps the mechanism simple and the machine reliable at this volume level.
Worth knowing: this is a light-duty desktop machine designed for sessions of up to around 300 sheets at a time. It’s perfect for daily mail runs, newsletter batches, programme sheets, and general office folding. It’s not built for continuous high-volume production – if you’re folding thousands of sheets a day every day, you’d want something larger. But for what it’s designed to do, the Martin Yale 7400 has earned its reputation as one of the best-selling desktop folders of all time.
Features
The 7400 includes automatic jam detection and automatic shut-off. The jam sensor stops the machine if paper feeds incorrectly, and auto shut-off kicks in when the feed tray is empty. The included catch basket sits underneath the machine and collects folded output in sequence, keeping everything stacked and ready for enveloping or distribution.
Setup is straightforward – it comes essentially ready to use out of the box. The machine runs from a DC power supply (included), measures 360 x 550 x 240 mm, and weighs 9.1 kg. It’ll sit comfortably on a desk, shelf, or worktop without taking up much space, and it’s light enough to move between rooms or store away when not in use.
