Maintaining the printer
Periodically, certain tasks are required to maintain optimum performance of your printer.
Warning—Potential Damage: Failure to maintain optimum printer performance, or to replace parts and supplies,
may cause damage to your printer.
Estimated number of remaining pages
The estimated number of remaining pages is based on the recent printing history of the printer. Its accuracy may
vary significantly and is dependent on many factors, such as actual document content, print quality settings, and
other printer settings.
The accuracy of the estimated number of remaining pages may decrease when the actual printing consumption is
different from the historical printing consumption. Consider the variable level of accuracy before purchasing or replacing
supplies based on the estimate. Until an adequate print history is obtained on the printer, initial estimates assume
future supplies consumption based on the International Organization for Standardization* test methods and page
content.
* Average continuous black declared cartridge yield in accordance with ISO/IEC 19752.
