GELJET Wide Printhead:
Smooth, High-Speed Printing
The GELJET wide printhead represents a
key component in creating both high-speed
and high-quality printing. With a 1.27-inch
nozzle row length—the longest in its
class—and 384 nozzles per printhead, the
width of an image that can be printed at
one time has been expanded, and high-density
printing has been realized. Furthermore, by
incorporating Ricoh’s Modulated Dot (M-Dot)
Technology for the optimal control of ink
size for plain paper, the printhead maximizes
the performance of GELJET viscous ink,
providing high-quality documents according
to printing speed.
GELJET BT System:
High-Speed, Laser-Quality Duplex Printing
The GELJET BT system is an innovative,
groundbreaking paper-feeding method. The
electrostatic transfer belt system, which is
used in laser printers, is optimized for inkjet
printing to provide a new feeding method.
This method prevents the bending of paper,
thereby eliminating the disadvantage in the
inkjet method. Stable printing quality has
thus been achieved, and feeding performance
has been greatly improved, especially for
paper edges. The GELJET BT system
maximizes the high-speed printing performance
of the GELJET wide printhead and achieves
high-speed automatic duplex printing
comparable to laser printing.
Challenges Faced by Business-Use Color Printers
Technology
Groundbreaking GELJET Technology
Ricoh’s innovative GELJET technology enables
high-speed, high-quality plain-paper
printing, which was said to be difficult for
traditional inkjet printers. The Company’s
ardent pursuit of its technology vision for
paper documents has brought about this
technology.
In the recent rapid colorization of office
documents, the need for fast in-house
color printing emerged, especially from
offices with few staff members. However,
traditional inkjet printers are slow and the
colors bleed on plain paper. Moreover,
the existing printers were mostly designed
and priced for general consumers and did
not meet the needs of corporate users both
in terms of speed and quality.
Ricoh’s GELJET technology, a
combination of the Company’s unique
inkjet technology and laser printing
technology, has given birth to a low-end
business color printer ahead of its
competitors.
GELJET Viscous Ink: Quick-Drying,
Clear, Waterproof Color Prints
GELJET viscous ink represents our core
technology in high-quality plain-paper
printing.
Thanks to its high viscosity and strong
permeability, GELJET viscous ink achieves
clear, quick-drying colors that do not run,
qualities that are required in high-speed
printing. Furthermore, by using pigment
colors for all four ink colors, images are as
waterproof as those made with toners.
GELJET viscous ink produces color
documents that can be used in various
business operations.
