As I may have mentioned elsewhere, during the month of December I made close to 2,000 11X17" prints with the Canon iPF 5000 without a single head clog. In fact, after 7 months not a single one.
I simply can't say that about the Epson Photo, 1200, 1270, 2000P, 4000, 5000, and 4800 printers that I've had over the years, where clogs are just a normal part of running such printers.
