Question 1

Which scanner specification most directly determines the ability to capture fine text details in scanned documents?

Accepted Answer

Optical resolution (dots per inch)

Answer

Optical resolution, measured in dots per inch (DPI), determines how finely a scanner can capture detail, directly affecting the legibility of small text.

Question 2

In a document imaging system, what is the primary purpose of an image enhancement step during capture?

Accepted Answer

To correct skew, remove speckles, and improve legibility

Answer

Image enhancement during capture corrects common scanning artifacts like skew, noise, and poor contrast to improve downstream OCR accuracy and readability.

Question 3

A company needs to scan documents at 300 DPI in grayscale. Compared to 300 DPI bitonal (black-and-white), the grayscale files will be approximately how much larger?

Accepted Answer

8 times larger

Answer

Bitonal images use 1 bit per pixel, while grayscale uses 8 bits per pixel, making uncompressed grayscale files approximately 8 times larger at the same resolution.

Question 4

Which technology enables a scanner to automatically detect whether a page is color, grayscale, or black-and-white and adjust settings accordingly?

Accepted Answer

Automatic color detection (ACD)

Answer

Automatic color detection analyzes each scanned page and applies the appropriate color mode, optimizing file size and quality without manual intervention.

Question 5

What does the term 'duplex scanning' refer to in document imaging?

Accepted Answer

Scanning both sides of a page in a single pass

Answer

Duplex scanning captures both the front and back of a page simultaneously or in rapid succession, improving throughput for two-sided documents.
