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.
