Print Yield
This section describes the approximate number of printouts that can be made per
cartridge.
Approximate Print Yield
Canon Cartridge X25: Approx. 2,500 printouts (A4 at 4% dot coverage*).
* The term "A4 at 4% dot coverage" denotes a document on which the area covered
with toner is 4% of the total area of an A4-size sheet.
• The actual number of printouts that can be made per cartridge depends in part on
the exposure setting, room temperature, and humidity.
• If you print a large number of documents which contain heavy print or many
photographs, toner consumption will increase, and white streaks will appear on
printouts sooner than indicated above. Toner consumption will also increase if you
print with the ADF left open.
• If you print small size documents or documents with less dot coverage, you may
be able to print more sheets of paper than indicated above. However, dark bands
might appear on printouts if you keep using the same cartridge for an extended
period of time.
