'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.
