This is a common problem with this printer. The inkjets have the tendency to clog, especially if you are not using the printer often, or even if you are using it often, but only printing black. Normally the "Head Cleaning" maintenance routine will clear the jet head. However, the cleaning process always takes an unacceptable amount of ink and in your case (and mine at this moment) the cleaning routine makes no improvement. Regardless of the routines failure, it still uses more ink than any normal person can afford. I am researching the issue and will post any helpful info I can find.
