2. Features
A. High reliability
(1) Improved Image Quality/Paper Transport
Full-Grip Path Design
Stable paper feeding realized by rollers that firmly grip paper
Small-Diameter Belt Transfer System
With reduced effect to paper types, drum paper release is stabilized
and transfer efficiency is improved
and transfer efficiency is improved
Easier Paper Jam Fixation with Open Paper Path
Jammed paper on vertical paper path can be easily removed by open-
ing the left side cover, which shortens time to fix paper jam

(2) Strengthened Frame Structure
Highly Rigid Frame
Improved stability with less machine distortion, and both rigidity and
lightweight been achieved.
lightweight been achieved.
(3) Energy Saving with Unique External Heat Roller
Fusing System
Newly Developed External Heating System
1) High reliability with stabilized fusing ability
2) Shortened warm up time before start copying
3) Achievement of energy efficiency that clears 2006 Rationalization
in Energy Use Law
External Heat Roller Fusing System
B. Network tandem
With Network tandem function, users can output one job on two net-
work connected engines. Productivity of large-volume copying/printing
can be dramatically improved by high-speed output of up to 110cpm
(55cpm model), 124cpm (62cpm model) and 140cpm (70cpm model)
work connected engines. Productivity of large-volume copying/printing
can be dramatically improved by high-speed output of up to 110cpm
(55cpm model), 124cpm (62cpm model) and 140cpm (70cpm model)
NOTE: Users can use the function simply by connecting the engines
to network. This means no Tandem Kit (Connection cable)
necessary.
For N model, only optional Printer Expansion Kit is required.
