Comparison Canon i-SENSYS MF247DW vs Canon i-SENSYS MF237W

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.

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.

Feature of a double-sided printing function. This mode implies that after printing on one side, a special gear turns over a sheet of paper and feeds it for printing on the other side. This not only saves the user from manual paper turn-overs, but also exclude the risk of printing the second side upside down.

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 noise level coming from the MFP during operation. The smaller this value, the more comfortable the use of the device. For office use, this parameter is not so important, but you should pay attention to it if you are going to use the device at home. It is easiest to evaluate a specific noise level using special comparative tables. For example, the quietest modern MFPs can operate with 34-35 dB noise level which is approximately corresponds to a muffled conversation, and the heaviest and most performant models give out up to 75 dB — this is comparable to a scream or a loud laugh at a distance of 1 m.

The maximum power consumed by the MFP during operation. The lower this indicator, the more energy-efficient the device is.
