1.  WHY DOES A DEFECTIVE CARTRIDGE HAVE TO BE 70% FULL? 

• A cartridge that has a manufacturers defect will become obvious immediately or at least within the first several copies made. 
• If a cartridge has been used past the 70% capacity, it is not considered defective. This is the same minimum requirement with almost all companies.
• Always send a sample of the problem in the box when returning a defective product.

2.  HOW ARE PRINT YIELDS DETERMINED? 

• It is the standard of the industry established by the major manufacturers:  HP, Canon, Xerox etc. to state a page yield for toner cartridges. 
• They determined that 5% page coverage is the standard to determine just how many pages a toner cartridge will produce.  If they state 2,000 pages, then that means you will get 2,000 pages only if the page has 5% of the page with words on it! 
• If you have a solid BLACK line or pie graft on the page, it will take a LOT more toner to fill that in and you WILL NOT get anywhere near 2,000 pages out of that toner cartridge. 
• Other factors are how dark you set your printer to print. 

3.  HOW LONG WILL A CARTRIDGE LAST? 

• There is no way to determine how long a cartridge will last. Time is not an accurate measure of how long the cartridge will last. 
• It simply depends on what you print, how many pages you print and how much print is on each page.  If you only print one or two pages each week, the cartridge will last a very long time.  If you print many documents with many words on it, the cartridge could run empty very quickly. 
• It’s like asking how long will a bottle of ketchup last?  It could last all year if you eat very little by yourself, or it could go empty in one day after a big party!
