Banding in inserted raster object

[ispfda]

I use AutoCad Architectural Desktop 3.3 to diagram out crime scenes. I also use Poser 4.0 to position bodies and then import them into Photoshop 7.0 to edit for transparency of the background. From there the body is saved either as a Tiff or Gif in order to preserve transparency and brought into AutoCad as a raster object. I set Transparency to on and set Frame to off.

We recently upgraded our primary printer to a Canon S9000 which we really like. However our bodies now appear with 1 or 2 stripes of white banding like the printer just did not print there. Other raster objects such as photos do not have this banding. However they have no transparency set in them. The Diagrams print fine on our HP 1200c so we know it isn't a problem everywhere. Could it be a driver issue?

I have been running a series of tests to perhaps narrow down a setting I have missed and the results are as follows:

1. Printer setting (standard/fine/draft) - No Change
2. Transparency On/Off w/ White background - No Change
3. Image Type w/ white background - No Change
4. Printer Model (Canon S9000 vs. HP DJ1200c) - Change
5. Image Background color w/ Trnasparency off - Change

From what I can determine, a white background for our bodies will not print correctly on our S9000. Does anyone have any suggestions of settings to change or different things to try? I have run out of thoughts. Thanks

I found this blurb about the S9000 ...

I printed the majority of my images using the default "Quality 2" setting and in only one print did I see any visible banding in a large patch of open blue sky. I went back and looked at a lot of my other prints including those with lots of sky but didn't see any other banding problems. By re-printing the image again using the "1" setting the banding was eliminated completely.
