Ever wondered what page yield actually means to you?

Whether you are buying a genuine, compatible, or remanufactured cartridge an
important consideration should always be how many pages can I print from the

Now Mr. Mc Scrooge would meticulously keep a record of each and every printed
page, and be contacting his solicitors for false advertising if the numbers of printed
pages was below the quoted quantity by the supplier.

But do you wonder why a T0621 compatible cartridge might last say only 6 weeks on
your Elson StylusC68 printer, after the previous one from the same supplier at the
same rated page yield lasted 3 months. “Something’s wrong with the cartridge” you
cry. But probably not.

Often the reason is due to varying levels of usage. For instance the cartridge
that lasted only 6 weeks might have had to produce the invitations to the annual
school fete, which you had volunteered to do as a member of the parents & citizens
committee of your local school. Also that invitation contained an image of last year’s
fete, along with attractions on the reverse side.

Another reason that the printer cartridge appears to expire before the quoted
number of pages is due to the page coverage. Page yields are based on the industry
standard of 5% page coverage, although page yield is different for every printer.
Thus there is no single page sample that would represent 5% page yield for all

In the above example of the Epson T0621 compatible cartridge, at ABC Print
Supplies we quote a yield of 450 pages (at 5% coverage). But if you were printing at
a page coverage of 10%, simple maths tells us that you will only achieve 225 pages,
and if you were printing multiple images, then perhaps you should order two or more
