The unique modular design of Acer scanners separates the optical scan module from the electrical module. This modular design makes for quick diagnosis of problems and easy maintenance. When fixing electrical problems, you can easily access the main board and the power board from the same opening in the bottom of the scanner housing. It is an interface standard of application software which is developed to ensure compatibility between scanner hardware and application software such as OCR and image editing programs. This standard enables users to scan images directly into application software without exiting the applications.
Scanners can capture different types of images based on their design.
When buying a scanner, it is important to note the type of images the scanner is equipped to capture. Line art includes text, charts, drawing, and any images that are entirely black and white. Halftones - This type refers to the way gray levels are represented. Halftones are created through a process called dithering, in which density and patterns of black and white dots are varied to simulate different shades of gray. Although some resolution is sacrificed, halftones do adequately represent the appearance of gray levels.
