N.B: What Do We Mean by 5% Coverage Page Yield?
Page yield refers to the approximate number of pages a specific toner cartridge is capable of printing. Determining page count can prove to be tricky as print density can vary from day to day for individuals. But some users simply print emails containing text moreover might be required to produce printouts of heavy graphics for brochures or catalogs as well as consequently printing much fewer pages than normal.
Other factors include room temperature, printer condition, and toner age.
It is for this reason that the printer industry came up with the 5% rule.
Manufacturers use such yardstick to guarantee.
How many pages a specific toner can yield. Firstly, 5% coverage would simply be a page printout of a text document containing no graphics with little or no bold characters on an 8.5 x 11 copy paper.  An increase or decrease in page yield is therefore directly proportional to an increase or decrease in page coverage.
