Some Brother inkjet printers display the remaining page yield on the printer's display.
The remaining page yields are approximated and may vary depending on the type of pages printed.
There are two methods used to measure the remaining page yields, "ISO-based" and "Usage-based". The printer will display the remaining page yields using the method you selected.

For more information on the "ISO-based" and "Usage-based "measuring methods see below:

ISO-based Method

These numbers are page yield data based on the industry standard for measuring ink cartridge yields (ISO/IEC 24711).
Actual page yield varies considerably depending on the content of printed pages and other factors.
ISO standard page yields therefore should be used only as a starting point for comparison purposes.

ISO/IEC 24711 Test Pattern for Measurement

The five standard ISO pages shown below consist of a mix of text and graphics, and a mix of black and color.

* To maintain good print quality, the machine will automatically clean the print head when needed. During the cleaning process, the machine draws some ink through the print head. Therefore the remaining page yield will decrease after cleaning.

Usage-based Method

These numbers represent the remaining page yield based on the actual previous usage of the machine. The previous usage is used to predict the approximate remaining yield as accurately as possible.

For example:
High density documents, such as <Document A> below, would display a lower page yield than the ISO standard, while less dense documents such as <Document B> below would display a higher page yield than the ISO standard.
Printing that uses mainly one color could cause lower yields for that color, and higher yields for colors not heavily used.
