Comparison Sharp MX-3070V vs Sharp MX-4070V

Black and white copy speed – the number of copies of one page that the MFP can produce in 1 minute. Typically indicated for poor print quality. This option is important if you often need to make many copies of a single document.

Colour copy speed – the number of full-colour copies of one page that the MFP can produce in 1 minute. Generally slower than black and white copy speed.

The number of pages the printer can produce per minute in black and white mode. Typically indicated for low print quality, higher print quality takes longer. This setting is important if you need to frequently print text documents.

The number of pages the printer can proceed per minute in colour mode. As like b/w printing, the print speed is usually indicated in the worst quality (at maximum speed), in higher quality the print speed is lower. This setting is worth paying attention to if you need to print colour graphic materials frequently.

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.

The maximum number of pages that the MFP can print in a month while remaining fully operational.

The minimal paper grammage that the MFP can print on. The grammage of the paper depends primarily on its thickness; thin paper takes up less space and weighs less, but using paper that is too thin can lead to unpleasant consequences, including jamming the sheets in the printer.

The amount of built-in memory provided in the MFP.

This parameter determines not only the amount of information that can be simultaneously stored in the device, but also the specifics of memory usage. With relatively small volumes of the built-in storage (up to 400 – 500 MB), it is mainly used to store print tasks and scan results — until the tasks are completed and digital copies of documents are transferred to their destination. Among high-end MFPs, there are modules, which volume is already calculated in gigabytes. Usually, the presence of this amount of internal memory means that the device has an extensive set of built-in tools, including the ability to use it as a temporary storage for document files.

The maximum resolution of the MFP scanner. It is usually indicated by two numbers indicating the number of dots per inch (dpi) horizontally and vertically, for example 1200x2400. The higher the resolution, the more dots the scanned image consists of and the smoother the lines on the digitalized copy and the better the fine details it displays. There are the following common resolutions: 600x600, 600x1200, 600x2400, 1200x1200, 1200x2400, 2400x4800, 4800x4800 and even more.
