The Roland VersaEXPRESS RF640 offers the perfect formula for digital printing success: high production speed, outstanding print quality, ease of use and unsurpassed reliability.
The genius behind the RF640 is reflected in its ability to quickly produce high quality graphics and
prints, while keeping cost of operation low. That translates into increased output, satisfied customers and more money in your pocket.
Like the rest of the Roland printer line, the RF-640 is easy to set up and operate. A redesigned front-loading ink cartridge unit facilitates ink replacement while minimizing the functional printer footprint. Media loading levers are positioned in both the front and back for maximum convenience. Special media brackets support even the heaviest media rolls as they are loaded into place, and adjustable media holders on both sides of the take-up system support the narrowest of rolls
