Cost Effective
EZ391U Digital Duplicator
Easy and Economical Ledger-Sized Printing
Duplicate to Save Costs
The RISO EZ391U digital duplicator makes prints from a master. As a result, the more
pages generated from each master the lower the cost per print, making the RISO
EZ391U highly economical for mid- to large-volume printing.
The RISO digital duplicator prints on a much broader range of media at speeds that far exceed
commonly used laser-based copiers. The RISO digital duplicator is specifically designed to handle run
lengths that are too long for copiers or laser printers.
In addition, the RISO digital duplicator allows organizations to bring many previously outsourced
print jobs in-house for maximum control and cost effectiveness. As a result, the EZ391U digital
duplicator becomes the ultimate economical, on-demand printing solution.
Printing cost per print
The printing capability of the EZ391U digital duplicator facilitates the handling of print jobs ranging
from everyday documents and business communications to more specialized applications like formson-demand, business cards, and even cardstocks.

Save Energy
A digital duplicator consumes as little as 1/6th*
the energy of a photocopier. For extra power
efficiency, the EZ391U features an ECO Mode
to minimize electricity consumption without
compromising print quality. After a specified
time in idle, the machine automatically enters
into sleep mode, reducing power consumption
by half; to just about 5W. Auto Power-OFF Mode
turns the power off.
Reduce Paper Consumption
Print two originals onto one sheet of paper
using the 2Up feature.
Versatility Supports Cost Management
Bring specialty paper stock jobs in-house to
avoid the costs of outsourced printing. The
EZ391U accepts multiple paper stocks; such
as newsprint, construction paper, envelopes,
postcards, and recycled paper. It handles legal
size as well. At 130 impressions per minute,
you can double or even triple printing output
without increasing printing costs.

Smart Design
1. Place the original on the glass and press the
start key to make a master.
Convenient Master Disposal Only from RISO
The intuitive design makes it easy to dispose of
used masters; the drawer-like box pulls out and
a vertical turn and a twist of the wrist allow easy
disposal of the used master.
Replace Consumables with Ease
Intuitive design simplifies routine operations
such as the ability to mount a new master from
the front of the machine and lock/unlock ink
bottles with a twist.
The EZ391U allows you to print from a wide variety of original formats. Multiple features
help improve printing productivity and output.
Optimize Your Output
For optimal output, the EZ391U features four
preset Image Processing Modes: Line, Photo,
Duo (line/photo/shadow), and Pencil (darker/

Improve Output through PC Connectivity
RISO EZ391U provides two ways to connect to a
PC. The optional USB port allows simple singlecable connection (RISO PC Interface card USB2.0).
The optional network card lets you put EZ391U
on your network (RISO Network Card). Produce
high-quality output with direct PC connectivity.

Programmable Printing, Reduces Manual
The Program Mode lets you specify the number
of copies in a set (up to 9,999), and the number of
sets in a group (up to 99) up to a maximum of 50
groups when printing from a single original; for
multiple originals (maximum of 20), up to 9,999
copies for each is possible.
Once the job parameters are programmed, they
can be stored in memory for future instant retrieval.
Output is automatically organized into groups
you specify, and can be further enhanced via
the optional Job Separator, which raises sorting

With an impressive monthly duty cycle and 130 impressions per minute the RISO EZ391U
is designed to handle a range of high-volume printing needs. The machine has been
rigorously tested to ensure compliance with these requirements (1,000,000 copy testing).
Additional Features
Green Is More Than Just a Color
RISO duplicators consume 1/6th* the energy
required to run multifunction printers. Features
like Auto Power OFF, Auto Sleep Modes and
the ability to print on recycled stocks with soybased ink make the EZ391U an environmentally
friendly printing choice. RISO
EZ series models are ENERGY
STAR certified, meeting a high
standard for energy-efficient
output devices.
Protect Your Information
The EZ391U User Management System allows
you to set up new user groups, rename, disable,
limit usage, and get usage reports*, giving you
control of your printing and budgeting needs.
There is also a Confidential Mode that prevents
