PRINT DATA PROCESSING 14 September 2000
2.2.2 UCR (IPD-C)
If the R/G/B data is equal (R=G=B), 100% UCR is applied only in the Black
Text/Graphic mode. Even if gray color is processed with RGB data, gray color will
be duplicated only with black toner if the RGB data is completely equal. This
function gives faster productivity. (This function was adopted on the base model,
RC-200.)
2.2.3 PURE BLACK FUNCTION (R-PS2)
For this new function, if the K value is 100% as a result of UCR (CMYK conversion)
in Text/Graphic mode, all CMY values becomes zero. This avoids colored text.
2.2.4 R-PS2 COLOR MANAGEMENT SYSTEM
Depending on the color setting (Off / Vivid / Supper Vivid / Fine / Super Fine),
image processing of color management differs as shown in diagram on the
previous page. (This CMS is the same as the base mode, RC-200.)

Image Processing In Controller
• RGB data is converted to CMYK with
almost 100% UCR.
The difference between Vivid and Supper
•
Vivid is the amount of CMY added to K to
give depth to images.
• RGB data is converted to Lab data; t hen,
the Lab color space is converted to a
targeted color space by using an em bedded
CRD or CRD downloaded from an
application.
• The difference between Fine an d Supper
fine is the target color space.
• Lab data is converted to the targeted color
space by using embedded C RD or CRD
downloaded from applicatio n.

14 September 2000 MINIMUM SPACE REQUIREMENTS
3. INSTALLATION PROCEDURE
3.1 MINIMUM SPACE REQUIREMENTS
Provide clearance for the copier, as shown below. If one or more options (such as
the ADF or sorter stapler) are added to the copier, this clearance should be
provided around the entire system. Please refer to the copier service manual for
more details concerning space requirements for this copier.
Installation
G549I123.WMF
NOTE: A space of at least 10 cm (3.9") at the rear of the machine is important for
machine ventilation.
