Comparison Canon i-SENSYS MF641CW vs Canon i-SENSYS MF237W

The number of colours supported by the MFP for printing. Black and white devices are perfect for printing documents with text information and simple graphics that do not require colour. Print quality on colour models can vary from medium to photographic.

The color palette that a printer or MFP can print. A large number of colors is required for high-quality photo printing and obtaining color prints with many shades. As a standard, for a color MFP, 4 colors are provided.

The time passed from pressing the Copy button to the completion of the first copy in MFPs. Typically specified for low quality black and white printing on A4 paper. The time for the first copy to be released is the longest (because of the time to prepare for work and scan the document); subsequent copies of the same document are printed much faster. Fast first copy time is important if you have to copy documents frequently.

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.
