Does Color Dropout Affect Productivity - Ricoh Aficio 3228C Manual

Rival MFPs can offer 2-bit or 8-bit
monochrome scanning which reduces the
bandwidth associated with color scanning,
but the color data is still present in the
document just in monochrome format. This
means that, at the least, the file size is
going to be greater, increasing
transmission time and storage space. It
can also mean that documents are more
difficult to process, especially if the colored
area is actually written over.
In the illustrations below, a sample health
insurance application form was scanned
using color dropout and in monochrome
modes. The second block of information,
which asks the user to write over a red
background, is virtually illegible in the
monochrome scan, which means that the
ICR process cannot be carried out
automatically. The scan using Ricoh's
color dropout technology is easily read and
can be fed directly into an ICR engine for
further processing.

Does Color Dropout Affect
Productivity?
In theory, color dropout could have an
impact in two areas of scanning: the
scanning speed and the overall time to get
the color removed before data
transmission can begin.
BERTL looked into this. We scanned 50
pages of a completed, standard
government tax form, running the same job
in both monochrome text mode and color
dropout mode. In both instances two times
were measured: the time to scan the
originals into the hardware (the point at
which the operator can return to their
desk), and the time before the file is now
accessible at the desktop. We carried out
the test on a clean 100BaseT network
using SMB protocol.
We were pleasantly surprised to find that
there was no slow down in the scanning
speed when color dropout was applied.
This means that the process will not be
adding to the cost burden of the company
in terms of human intervention time.
We were even more pleasantly surprised
to see that the data transmission time
