"ghost" image on Pixma MP970

[john doe]

Hello all,
When printing, the color parts generate like a "ghost image", that is larger than the original and located on the right, but lighter and in grey. Other than this "ghost image", the print is fine.

- Debian Squeeze, i386
- cups 1.4.4-3
- cups-bjnp-0.5.4
- Driver:	Canon PIXMA MP970 - CUPS+Gutenprint v5.2.6 (color, 2-sided printing)
- Connection:	bjnp://canon-mp970:8611
- printing over the network

Does anybody have an idea on how to correct this problem? (BTW, the scanner is just doing fine over the network).

Thanks for your input - tom
