Canon ip6600D connected via USB port. I am getting a Majenta smudge down my photo prints (using glossy photo paper). It appears in exactly the same place regardless of being A4 or 6x4. Occurs in a stripe across the page which is about 19mm in from the end of each print. The remainder of each print is perfect. I am using the Paper feed tray although I have tried printing from cassette with same issue.
If I print on plain paper it seems to be OK.
The printer has been cleaned (canon service centre). The paper is not curled in any way. I haved downloaded the latest drivers and I have tried printing from different programs, Photoshop, Picasa, Canon photo print.
