Maven MF-3220 K12

It is right for shops printing more than 60 m² of rigid material a day — signage, facade panels, furniture components. Below that the machine does not repay itself and the MF-2513 R8 is the smarter buy on both capital and running cost. If you cannot provide 45 m² of clear floor, 3.5 m of ceiling and crane access, there is no point discussing it.

The published 75–84 m²/h band covers every configuration from four heads to eighteen, with the lower end being the smaller array. The real return on head count is not raw speed but holding that speed at a higher pass count — 47–54 m²/h at eight passes. And to be plain about it: eighteen KM1024i heads represent a significant share of the machine's value, and a failure replaces one head, not the array.

Speed drops, drop size shrinks. The same chassis runs 60–72 m²/h at four passes with Ricoh Gen6, but the 5 pL drop handles pass banding and skin tones better than the 6 pL KM1024i. Volume work belongs on Konica, quality-critical work on Ricoh.

The closed-loop chiller takes a deionised water and glycol change once a year, with a filter check every six months. Skip it and the problem does not appear in the chiller — it appears in the LED modules, one of the most expensive items on the machine.

The machine weighs 2580 kg carried on four feet, so the slab must be flat to ±3 mm per metre and free of vibration. Electrically it is 220 V three-phase at 45 A with a 10 kW peak. The crate is 5900 × 3300 × 1900 mm — we check door and corridor dimensions with you before the order is placed.

Colour-white-colour work lays down three layers, so output falls to roughly a third, and spot varnish adds another pass on top. If clear acrylic and dark substrates dominate your mix, plan capacity around that lower figure rather than around 75–84 m²/h.
