*Capacitors are incorporated only in the 100v machines
marketed in Japan.
Hybrid QSU, which is incorporated into the
imagio Neo752 series, is the industry’s first
hybrid heat source. Hybrid QSU is an inte-
gration of a next-generation electrical storage
device; capacitor and Ricoh’s quick start-up
(QSU) technology. QSU technology makes
use of an ultrathin-shell fusing roller, which is
essential for a quick restart, to enable high-speed
printing of 75-pages-a-minute. Unfortunately,
the heat of the fusing roller is easily transferred
to the paper, which deteriorates printing quality
and speed. To solve this problem, sufficient
heat needs to be supplied to the fusing roller.
Ricoh therefore decided to use its quick charging
and discharging capacitor technology. During
standby, the capacitor stores power, which
restores heat to the fusing roller after the heat
is transferred to the paper during printing.
The machine is therefore able to maintain
productivity at 75-pages-a-minute while
requiring only 30 seconds to warm up
(1/10 the time of existing machines) and
has an energy consumption efficiency of 117
Wh/h (about 1/2 that of existing machines),
which is the best performance in the high-
speed machine category.
The Energy Conservation Chairman’s
Prize at the 14th Energy-Saving
Awards
The imagio Neo752/602 series won the Energy
Conservation Chairman’s Prize at the 14th
Energy-Saving Awards sponsored by the Energy
Conservation Center, Japan. imagio Neo752
series are equipped with capacitors that are
attracting attention in the industry as next-
generation electrical storage device. This is the
third time for Ricoh to receive the Energy-Saving
Award after the imagio Neo350 series and the
imagio Neo220/270 series won the Award.
The Grand Prize at the 12th Global
Environment Awards
In recognition of its global leadership in
environmental conservation
activities such as Zero Waste
to Landfill, prevention of global
warming, and social contribution,
as well as its endeavors to improve
public environmental awareness,
Ricoh received the Grand Prize at
the 12th Global Environment
Awards.
The Minister of Economy, Trade
and Industry Prize at the 6th Green
Procurement Awards
Ricoh was awarded the Minister of Economy,
Trade and Industry Prize at the 6th Green
Procurement Awards
sponsored by the Green
Purchasing Network for
its Green Partnerships
(green procurement,
green purchasing, and
green marketing).
