Epson Perfection V39

How many pixels a scanner can see. Most commonly, this is measured in dots per inch (dpi).For example, a typical flatbed scanner will use a scanning head with 300 sensors per inch, so it can sample 300 dots per inch (dpi) in one direction. To scan in the other direction, it will move the scanning head along the page, stopping 300 times per inch, so it can scan 300 dpi in the other direction as well. This scanner would have an optical resolution of 300 x 300 dpi. Some manufacturers stop the scanning head more frequently as it moves down the page, so their machines have resolutions of 300 x 600 dpi or 300x1200 dpi.

Feature of computer scanners and multifunction printers (MFPs) that allows the automatic scanning of a sheet of paper on both sides.

Colour depth of the input into the product. The colour depth is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color component of a single pixel. High-end laptops have 24-bit colour depth.

Device made for scanning photographic film directly into a computer without the use of any intermediate printmaking. It provides several benefits over using a flatbed scanner to scan in a print of any size: the photographer has direct control over cropping and aspect ratio from the original, unmolested image on film; and many film scanners have special software or hardware that removes scratches and film grain and improves color reproduction from film.

A scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Common examples found in offices are variations of the desktop (or flatbed) scanner where the document is placed on a glass window for scanning. There are different types of scanners e.g. flatbed, pen, sheet-feed.

The colour e.g. red, blue, green, black, white.

A sensor is a convertor than measures a physical quality (light, temperature etc.) and displays this electronically on a device.

Most common industry-standard communication protocols ranging from RS-232, RS-422, RS-423, RS-485, and LVDS to USB.

The Restriction of Hazardous Substances (RoHS) Directive aims to restrict certain dangerous substances commonly used in electrical and electronic equipment. Any RoHS compliant product is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). PBB and PBDE are flame retardants used in several plastics. For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance.

This indicates that the product is compliant with Energy Star, which is an international standard for energy-efficient consumer products.
