Xerox Phaser 5500 Supplementary Guide

The ISO/IEC standard allows for objective comparisons of stated toner yields for different
printers or MFPs, regardless of OEM. Many prospective customers use consumable yield
information to estimate the toner life they can expect to experience with their particular
applications, and adherence to the ISO/IEC standard enables this analysis.
It is important to note that the ISO/IEC yield is a comparative statistic and not a
predictive tool. The number of pages that customers will get for their own applications
will depend on a variety of factors, with page coverage having the highest impact.
Research has shown that the industry average black-and-white page coverage is
between 4% and 5%. There is an inverse relationship between page coverage and toner
yield — the lower the page coverage, the more pages the toner will yield. Conversly,
higher coverage pages result in lower toner yields.
Customers utilizing heavy page coverage applications will achieve lower toner/ink yields.
Most Xerox Phaser
®
printers contain an important feature called Usage Profile that gives
customers access to page coverage data on a job-by-job basis, or on average for all jobs
printed by a specific printer. This data can be downloaded to a Microsoft Excel file, or
viewed online via Xerox CentreWare® IS Embedded Web Server. Using this information,
customers can estimate if they will achieve higher or lower toner yields compared to the
declared ISO/IEC standard yields.
Other Consumable Testing
Currently, only toner cartridges and solid ink sticks are subject to ISO/IEC yield
standards. Drums (or imaging units), fuser units, and maintenance kits are not covered.
Yields are published based on the OEM’s own testing methodology. Users should be
aware of the factors that can impact drum and fuser yields, as these are longer-life
consumables that can be significantly impacted by usage patterns and certain types of
media. Xerox printers and MFPs reporting drum and fuser yields will use the following
description/disclaimer:
Drums/Imaging Units:
Approximately XX,XXX standard pages
2
2
Declared Yield based on an average job size of 3/4/5 pages letter/A4-size.
Yield will vary based on jub run length, media size and orientation.
Note: Most drum yields are based on 3-page or 4-page average job size. On some high
performance products (such as the Phaser 5500), drum yields are based on 5-page
average job size. Standardizing Drum Yield testing across XOG will be very important to
increase Customer Satisfaction and reduce liability to Xerox.
Fusers/Maintenance Kits:
Approximately XXX,XXX standard pages

Declared Yield based on letter/A4-size 20 lb. (75 gsm) pages. Yield will
vary based on media type, size, weight, orientation and usage patterns.
