Offering exceptional productivity and value, RISO’s EZ591 digital duplicator is the best choice for a mid-range model with a high-end feel! New features, advantages, and benefits, including the new ECO Mode and Photo Adjustment, make the EZ591 more than just the flagship of the EZ series. Like all RISO digital duplicators, the EZ591 brings versatile printing capabilities to any environment. The new Photo Adjustment option permits more control over photo reproduction, such as contrast and tone curve adjustments. Additionally, the EZ591 will allow you to print on a wide range of stocks from thick media to odd-sized and die cut stocks, recycled papers, envelopes, and more!
The EZ591 is a ledger-sized digital duplicator with an integrated GDI controller, offering 600e dpi imaging, 11” x 17” printing and scanning, glass platen, and a large intuitive LCD touch panel. Additionally, the EZ591 has the ability to print directly from a USB flash drive, offering more control and improved output over scanned originals. As with all EZ duplicators, the EZ591 is equipped with the RISO i Quality system for optimum performance.
The EZ591 is equipped with an all new ECO Mode, setting new standards for environmentally-friendly printing! ECO Mode decreases the printing pressure and the LCD touch panel brightness, reducing power consumption by 5%. The EZ591 is ENERGY STAR certified, making it a sound environmental choice!
USB Flash Print: Achieve digital print quality by no means of direct connectivity! For confidential or last-minute print jobs, you can simply use your USB flash drive to get the job done. It is as simple as saving your documents to your USB drive and using the tools to queue jobs up for printing.
User Management allows you to set up 100 accounts and 32 groups, making it simple to budget by department or user groups, eliminating the need for key card counters. This feature allows you to take control of your printing and budgeting needs, as you will be able to set up new user groups, rename, disable, limit usage, and get usage reports!
Two-way communications between RISO i Quality System-equipped printers and their suppliers is made via integrated RF (Radio Frequency) tags. These tags relay information to the printer, assuring optimum first print quality and superior output throughout the entire job.
