Consumable Life Expectancy Chart
"
The values listed in the below tables indicate the number of pages for
simplex printing using A4/Letter-size media with 5% coverage.
The actual life may differ (be shorter) depending on the printing condi-
tions (coverage, paper size, etc.), differences in the printing method,
such as continuous printing or intermittent printing (when print jobs of
one page are often printed), or the type of paper used, for example,
thick paper. In addition, the life will be affected by the temperature and
humidity of the operating environment.
