Toner Cartridge Yields

Toner cartridge yields are provided as approximate values based on ISO/IEC standard testing methods.

5% coverage is a measure that most printer manufacturers use to calculate the number of pages that can be printed with one cartridge. It means that 5% of the whole page is covered in ink or toner. When doing the calculation, printer manufacturers assume basic type with no bold characters, no graphics, and no pictures.

Standard Yield: The ink or toner cartridge prints a standard number of pages at 5% coverage.
High Yield: A high-yield cartridge will print more pages than a standard yield cartridge. Although the initial outlay is higher, the cost per page is lower.
