Scan

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
