Autofeed
The maximum amount of sheets that can be loaded into the MFP's document autofeed at one time.
The autofeed makes it easy to scan and copy a large amount of documents - just load a stack of sheets and turn on the programme, after which each document will be automatically fed for scanning. An auto-feed MFP is worth considering if you frequently scan or copy a large amount of documents.
Cloud printing
Cloud-enabled MFPs allow you to work directly with cloud services without connecting to a PC.
The general point of such printing is that the documents sent for printing (and in the case of MFPs, also scanned materials) are stored on a server on the Internet. Thus, the connectivity of the printer/scanner is not limited to the local network — you can send documents for printing and receive scan results from anywhere in the world where there is access to the World Wide Web. In addition, cloud services make it easy to share access to the MFP and other people.
Note that cloud printing can also be used with MFPs, that do not have such a function by themselves — for this, you need to connect the device to a PC with the appropriate software.
Diagonal
The diagonal of the display installed in the MFP.
The larger the display, the more convenient it is to use, the better you can see the image on it.
MFPs with a large display(from 7" and above) are especially convenient when you need to view various graphic materials on the screen — for example, photos for printing or scanned results. In addition, a large diagonal is highly desirable for touch screens (see "Display "). On the other hand, the larger the display, the more expensive it is and the more space it takes up, despite the fact that a small diagonal is enough for basic tasks and settings (this is already better than
models without a display). Therefore, even in the most advanced models this indicator does not exceed 10.4", and in general, large screens are typical mainly for high-end MFPs with an abundance of additional features.
CPU frequency
The clock speed of the processor installed in the MFP. Theoretically, the higher this indicator, the faster the device is able to handle with various tasks; high performance is especially important when printing high quality images, scanning at high resolutions, etc. However, in fact, the capabilities of the MFP, in addition to the processor, depend on a number of other specs, and this point is more for reference than practically significant, and when choosing, it is worth focus on more obvious performance specs (copy speed, print speed, etc.).
Scanner Colour Depth
The colour depth supported by the MFP scanner. This setting determines the number of colour shades that the device can recognize. Therefore, the overall quality of the scan directly depends on it (although other features of the device also affect this quality).
Of course, it makes sense to be focused primarily in colour depth if you plan to intensively use the scanner for full-colour images like photos, paintings, etc. If the MFP is purchased mainly for documents, where the maximum variety of colours is the logo on the letterhead or the stamp, it barely makes sense to pay special attention to this spec.
As for the colour depth, we note that the total number of recognizable shades can be determined using the formula “two to the power of the number of bits”. For example, a 24-bit scanner will recognize 2^24 = 16.7 million colours (approximately). This value is considered quite sufficient for everyday use, and 36-bit is also sufficient for relatively simple work tasks such as printing brochures and other images that do not require high colour fidelity. But for professional work with colour, you should choose more impressive scanners; in the most advanced models, the colour depth can reach 60 bits.
