Overview
  - This pack contains cyan, magenta and yellow high yield ink cartridges, 
  each covering up to 1500 pages (at 5 percent coverage). Cartridges are 
  suitable for use with our MFCJ5330DW, MFCJ5730DW, MFCJ6530DW, MFCJ6930DW 
  printers. 
What Does 5% Coverage mean?
  - ‘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. 
What does standard yield mean? 
  - The ink or toner cartridge prints a standard number of pages at 5% 
  coverage. 
What does high-yield mean? 
  - 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. 
  
What does super-high-yield mean? 
  - Super-high-yield cartridges give you an even lower cost per page, because 
  they print even more pages.
