Question 1

In document imaging, what is the purpose of a 'separation sheet' when scanning a batch of documents?

Accepted Answer

To signal the scanner software to create a new document boundary

Answer

Separation sheets (often barcoded) are placed between documents in a batch so the scanning software automatically creates new document boundaries without manual intervention.

Question 2

Which factor most significantly affects the readability of OCR output when scanning text documents?

Accepted Answer

The scanning resolution and image quality of the input scan

Answer

OCR accuracy is heavily dependent on the input image quality, particularly resolution — scanning at inadequate DPI or with poor contrast leads to character recognition errors.

Question 3

What is 'bit depth' in the context of scanned document images?

Accepted Answer

The number of bits used to represent the color of each pixel

Answer

Bit depth refers to how many bits encode each pixel's color value; higher bit depths allow more shades or colors, affecting image quality and file size.

Question 4

An organization scanning historical documents needs to capture fine details and subtle tonal variations. Which combination of settings is most appropriate?

Accepted Answer

600 DPI, grayscale or color

Answer

High-resolution (600 DPI) grayscale or color scanning preserves the fine detail and tonal gradations needed for historical document archiving and analysis.

Question 5

What is the role of a 'document feeder' (ADF) in a production scanning environment?

Accepted Answer

To automatically advance pages through the scanner without manual handling

Answer

An Automatic Document Feeder (ADF) automatically moves a stack of pages through the scanner sequentially, enabling unattended high-volume scanning.
