Questions and Answers

Xerox compliance with ISO/IEC standards
Q: Will Xerox provide "ISO/IEC certificates" for supplies that have been ISO/IEC
yield tested?
A: The ISO/IEC certification process does not result in the issuance of certificates. By
declaring a yield according to ISO/IEC standards, Xerox warrants that it has done the
testing according to ISO/IEC standards and guidelines. This declaration will be found
in data sheets or collaterals that list consumable supplies yields.
Q: Does Xerox publish its ISO test results?
A: Yes. They can be found online at www.office.xerox.com/iso/.
Q: Will all Xerox supplies declare yields according to the ISO/IEC standard?
A: Declared yields for new Xerox office products will adhere to ISO/IEC standards. Xerox
black-and-white products have been using ISO/IEC 19752 for some time. ISO/IEC
19798 and ISO/IEC 24711 was published in December 2006. Xerox will re-test toners
for past products using ISO/IEC standards as conditions permit. The latest yield
information for Xerox printer and MFP toner cartridges/solid ink sticks can be found
online at www.office.xerox.com/.
Stated Yield vs. Actual Yield
Q: Can I get the ISO/IEC yield for my specific printing application?
A: No. The ISO/IEC standard ensures that the stated consumable yields of different printer
and MFP OEMs are comparable by specifying a set of common testing parameters
and conditions. It is not guaranteed that users will get the declared yields in their own
applications, as page coverage varies by application, and page coverage has the highest
impact on actual yields. User applications running at approximately 5% page coverage
under normal office operating conditions can expect on average to experience yields
that are fairly close to the ISO declared yields.
Q: What are the factors that will impact the yields users get from toner cartridges?
A: The most important factor affecting yield is page coverage. Coverage analysis has
consistently shown that in office environments, the average black-and-white page
coverage is in the range of 4% to 5%. However, it is not unusual for office applications
to run above or below that average. In general, pages with significant dark or shaded
areas (logos or pictures) or a large amount of fine print will generate area coverage
higher than 5%. Other factors that can reduce toner cartridge yield include higher
temperature, higher humidity levels and using a higher print resolution setting.
