Max. scan area

The maximum image size that the scanner can process at one time, both horizontally and vertically. You should pay attention to this parameter if you need the exact dimensions of the scanner's working area, down to a millimetre: although standard formats are used to designate these dimensions (see "Format"), in fact the dimensions may differ from them.

Colour depth (int.)

Under the internal colour depth is meant the number of shades of the image that the scanner itself can recognize; it should not be confused with external depth, which is the amount of hue transmitted to the computer (see below). Colour depth is expressed as the number of bits of information used to encode data about each colour. The total number of colour shades in this case is 2 to the power of n, where n is the colour depth. So, a 24-bit scanner recognizes 16.7 million colours — which is more than one and a half times more than the human eye, and quite enough for simple everyday tasks. In more advanced professional models, colour depth can reach 96 bits. Although the characteristics of the image transmitted to the computer are described by the external colour depth (which can be less than the internal colour depth), the internal depth, however, also affects its quality: other things being equal, a scanner with a higher internal depth provides more accurate colour reproduction.

Colour depth (ext.)

External colour depth characterizes the maximum possible number of colour shades in the image transmitted by the scanner to the computer. A depth of 24 bits is considered quite enough for non-professional tasks, in more advanced models this parameter can reach 96 bits. For details on colour depths and their relationship, see "Colour Depth (Int.)"

Shades of grey

The number of shades of grey that the scanner recognizes. You should pay attention to this parameter if you plan to actively work with complex black-and-white materials (for example, photographs) — the more shades, the higher the quality of the digitized image. To date, the average is considered to be 512 shades — this approximately corresponds to the capabilities of the human eye. Models with a lower indicator belong to the entry level, more advanced ones “understand” 1024 shades.

Document autofeed

The maximum number of sheets of standard weight (80 g/m²) paper that can be placed in the scanner's auto feed system at a time. These systems are similar to those installed in printers: a stack of sheets is installed in a special tray, and each of them is fed in turn for scanning. It is worth paying attention to models with this function if you often have to work with numerous documents: you will not need to monitor the process and manually feed sheets — just load the originals into the automatic document feeder and press the button. Many document feeders, some flatbeds, and almost all combination scanners have an ADF (see "Type"). It works, however, only with separate sheets and cannot cope with larger media.

Noise level

The maximum noise level produced by the scanner during operation. Theoretically, the lower this parameter, the more comfortable the use of the device, however, the vast majority of scanners have a noise level much lower than the general sound background in a small office (this background is 40-50 dB). Therefore, it is worth paying special attention to the noise level if you plan to use the device at home at a later time, or in other environments where even a slight noise may be undesirable.

Power consumption

The maximum power consumed by the scanner during operation. The higher the power, the more energy the scanner consumes, but this only applies to the scanning process itself — in standby mode, power consumption is negligible. And even at the peak in most models, the power is so low that in fact this parameter has practically no effect on electricity bills and is more of an auxiliary value (for example, it is used to calculate the total power of devices connected to an uninterruptible power supply).
