Plustek 3900 Compact ScanPro

The set of colour options that a scanner can produce when scanning an image or document. Each value represents a supported mode such as "Grayscale", "Monochrome", or "Colour" and may be listed separately if multiple modes are available.

Indicates whether a scanner can perform color scans. The value is "Yes" if the device supports color scanning, and "No" if it only performs monochrome scans.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

Indicates whether a device can scan both sides of a sheet in a single pass. A value of "Yes" means the scanner automatically captures the front and back of each page, while "No" indicates that only one side can be scanned at a time.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

The number of distinct colours that a device can capture or process from an input source, expressed as an integer value such as "48 bit" or "24 bit". This metric indicates the richness and fidelity of colour reproduction for scanned images or captured media.

The main illumination source used by the product, such as LED, laser, CCFL, or other light-emitting technologies. It indicates whether the device uses a single light source or multiple sources and helps users understand the lighting characteristics of the item.

A list of macOS operating system versions that the product supports or is compatible with, such as "macOS 10.15 Catalina", "macOS 11 Big Sur" or newer releases. Each entry represents a distinct OS version that can run on or be supported by the device.

The largest standard ISO A-series paper format that a device can handle, expressed as the ISO code (e.g., "A4", "A3"). This attribute indicates the maximum sheet size supported by printers, scanners, copiers, and similar equipment.

The largest document dimension that a scanner can capture in a single pass, expressed as width by height (e.g., 216 × 356 mm). This value indicates the maximum area the device can scan without needing to cut or stitch images.

The minimum processor model required for a product to operate correctly. This attribute lists the specific CPU model or brand that meets the device’s baseline performance needs, such as "Intel Core i3-8100" or "AMD Ryzen 5 3600". It helps users verify compatibility and ensures the product will run with acceptable speed and features.

The smallest amount of system memory required for a product to operate correctly, expressed in gigabytes or megabytes. This value indicates the minimum RAM capacity that a device must have to run its software and hardware components without performance degradation.

The smallest amount of internal or built‑in storage that a product requires to operate, typically expressed as a numeric value with an appropriate unit such as GB, MB, or TB. This attribute helps users understand the minimum space needed for the operating system, essential applications, and basic usage.

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 number of distinct colours that a device’s output can represent, expressed as an integer followed by the unit "bit" (e.g., 24 bit). This metric indicates the richness and fidelity of colour reproduction for images or video sent to the device.

The type of electrical supply that powers the device, such as mains AC, DC, USB, battery, or a combination of these options.

The colour(s) that a product displays, which may be a single dominant hue or a combination of hues such as "Black, Silver". The value is expressed in common colour names and can include multiple colours separated by commas.

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.

The type of sensor technology used by a device to detect and measure physical quantities such as light, temperature, motion or pressure. Common values include CMOS, CCD, CIS, BSI, laser, ultrasonic, and other specialized sensor names.

The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.

The horizontal measurement of a component or part, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
