This RTB outlines the major differences between the Russian-C1 and Russian-C2.
Overview:
The R-C2 is intended as the successor model to the R-C1. The mechanical components
and design of these two models are nearly identical. In addition, the electrical system of
the R-C2 employs GW architecture.

Note:
1) The R-C2 has a new exterior color (same as A-C2).
2) The Drive Motor and Control Board for these peripherals have been changed so that the
peripherals can be installed on the high cpm machine (R-C2c).

The control for this function has been changed
over to a software switch (op. panel).
• Thin hot roller
• 2 fusing lamps
• 4 thermostats
• 2 thermistors
• The fusing temperature control and Energy
Saver function are very similar to those of
the A-C2.
• The ID sensor pattern creation time has
been changed so that it is performed at
power-on and at a specified interval (#

• Toner density control is the same as for the
R-C1.
• The cleaning pad for the charge roller has
