First page print
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.
B/W printing
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.
Black Ink Page Yield
Approximate number of pages that the MFP can print in black and white mode without replacing the cartridge. In fact, this greatly depends on the specs of the images to print, so the actual resource may greatly differ from the claimed one in one way or another. Nevertheless, according to this indicator, it is quite possible to evaluate the capabilities of the MFP and compare it with other models.
Grammage (max)
The maximum grammage that the MFP can print on. The grammage of the paper depends primarily on its thickness; thick paper is strong, but if it is thicker than allowed by MFP's manufacturer, the paper feeder simply cannot handle such sheets.
RAM
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.
Feed tray
The maximum number of sheets that can be loaded into the MFP feeder at one time. Blank paper is taken from the feed tray for subsequent printing; the more sheets fit there, the less often you will have to reload the MFP with blank paper.
Power consumption
The maximum power consumed by the MFP during operation. The lower this indicator, the more energy-efficient the device is.
