Ryobi 3404DI - Manual (Page 6)

User-Friendly Operation Thanks to Automation
Simple, Straightforward Centralized
Control from the Operation Stand
All major operations for the RYOBI 3404DI are
initiated and controlled from the operation stand.
Setting the number of printed sheets; job data
entry, interruption and recall; presetting the ink
fountain keys; and cleaning are all centrally
controlled from the operator’s position. A large-
format 14.1-inch LCD ensures user-friendly
operation.
Automatic Ink Fountain Key Presets
Calculating the image area ratio for each color is
done simultaneously with imaging. Presetting the
ink fountain key is done automatically from the
operation stand based on this data. This allows
easy control of the ink fountain key opening
volume, dramatically reducing the time and effort
involved in making color adjustments.
RYOBI Program Inking
RYOBI Program Inking automatically supplies ink
to the ink rollers to match the image from the
very start of printing. After the set number of
prints is finished, the ink on the rollers is auto-
matically restored to an even state, allowing the
operator to proceed quickly to the next job and
minimizing the amount of wasted paper generated
at the start of printing.
The RYOBI 3404DI is loaded with automated processes, from
plate advance and imaging to making color adjustments—
operations that once required high levels of experience and skill.
Its user-friendliness ensures that even operators with little
experience can achieve quality printing in a short period of time.
Convenient
Auto Print Function
The RYOBI 3404DI features a
convenient Auto Print function.
Printing operations start just
by selecting the Auto Print
command on the operation
stand’s monitor screen. Plate
advancing, imaging, printing and
blanket cleaning are all carried
out at a click of a button.
Automatic Cleaning
Devices
The RYOBI 3404DI comes
standard with an automated cleaning system for
both ink rollers and blankets (including an impres-
sion cylinder cleaning function). This reduces the
cleaning time required when switching jobs, thus
lessening the workload for the operator.
RYOBI PDS-E
Printing Density Control System
(option)
The RYOBI PDS-E Printing Density Control System
is an option on the 3404DI. Color adjustments
previously based on the experience and intuition of
the operator can now be made using numerical
values from solids densities calculated for each
color. This system allows the operator to easily
match printing output to the OK sheet and keep
quality consistent.

Note: Manual ink volume adjustment may become necessary depending on the printing conditions such as ink, stock and print image (especially when printing
a much lighter image job after a heavy solid print job.)
