What do we mean by page yield
What do we mean by page yield?

You may have wondered how we come up with our page yield estimates.  The page yield is based on 5% page coverage.  That’s about the equivalent of printing a short letter with a header.  Why 5% you may ask?  That number comes from the International Standards Organization.  They’re the group that decides how long a centimeter is and how much a pound weighs.  They also set the industry standard for measuring page yield for printer cartridges.  This is good for buyers because all of the major manufacturers including HP, Canon and Brother use the same standard.  When you compare cartridges from different sellers you know you’re comparing apples to apples.      


What does ISO certified mean?

ISO stands for the International Standards Organization.  The 9002 certification represents an international consensus among experts about how a factory can maintain quality standards.  In order to receive the certification, a manufacturer must pass rigorous tests to prove that they have implemented good procedures to monitor the quality of the goods they produce.  When you see this certification you can be confident that your cartridges are made by a professional facility according to strict quality standards. 

Do Sophia Global cartridges come with chips?

Our cartridges DO in fact come with chips.  This means that there is no need to remove any part of an old cartridge to use the cartridges you have ordered from us.  Upon receiving and opening your order of cartridges, place them in your printer and you are ready to go!
