The maximum number of black‑and‑white pages a scanner can process per minute when using its automatic document feeder (ADF) with A4 paper. This value indicates the speed at which documents are scanned and is useful for comparing throughput across models.

The maximum number of pages a scanner can process per minute when scanning in either black‑and‑white or colour. This value indicates the throughput capability of the device and allows users to compare how quickly different scanners can digitise documents.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The maximum number of pages a scanner can process in a single day under normal operating conditions. It indicates the device’s capacity for continuous use and helps users gauge how many documents it can handle before requiring maintenance or downtime.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

Indicates whether the product is a wire‑cut item (custom cut to size) or a stock item (pre‑cut to standard dimensions). This attribute helps buyers understand the manufacturing process and potential customization options.

The range of electrical voltage that a device can safely accept from its power source, expressed in volts (V). It specifies the minimum and maximum supply voltages compatible with the product, covering both AC and DC inputs where applicable.

The largest document dimension (width × height) that a scanner can capture in a single pass when using an Automatic Document Feeder (ADF). The value is expressed as a physical measurement, typically in millimeters or inches. This attribute helps users determine the maximum size of material that can be processed without trimming.

The smallest document dimension (width × height) that an Automatic Document Feeder can capture in a single pass, expressed in millimetres or inches. This value helps users determine the minimum size of material that can be scanned without trimming or manual handling.

The pixel dimensions of a scanner’s optical sensor, expressed as width by height (e.g., 1200×2400). It indicates how many pixels can be captured per scan and determines the sharpness and detail of scanned images.

The type of electrical supply used by the product, such as AC mains, DC power, USB power, battery, or a combination of these options.

A list of communication interfaces or software protocols that a scanner can use to transfer scanned images to a computer or network, such as TWAIN, WIA, SANE, ICA, ISIS, and others. Each entry represents an available option for connecting the device to capture software.

The functional configuration of a scanner, indicating how documents are fed into the device. Common types include flatbed scanners with automatic document feeders (ADF), sheet‑fed scanners, single‑pass or dual‑pass ADFs, and specialized modes such as 1D/2D barcode readers. This attribute helps users understand whether the scanner can handle single pages, multiple pages automatically, or specific scanning formats.
