Printhead+Expected+Life

=What is the expected life of the Canon printheads?=

Canon has published a document "Expected Printhead Life Guideline". While the expected printhead life is VERY good, this information highlights how poor the warranty is: expected printhead life is 14,000 pages for both printheads, but warranty is for 4,000 ml or one year, whichever comes first. In other words, the warranty covers just under 50% of the expected printhead life, a lot less if you are a low volume printer and take longer than one year to reach the 4,000 ml per printhead. The iPF printheads are VERY expensive and have a limited warranty both timewise and in terms of warranted throughput. **Counterbalancing this concern:** there have only been a few reports of premature printhead failure (all were replaced by Canon under the warranty) and a number of reports of people who printed a lot more than the warranty amount without printhead failure.
