Canon Pixma MP800 RGB colours offset

This was scanned at 600dpi, the Ubuntu one was scanned at either 1200 or 2400.

It seems that Launchpad cannot handle the link to Alioth bug tracker.
The link is: http://alioth.debian.org/tracker/index.php?func=detail&aid=310463&group_id=30186&atid=410366

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks again!

I have the exact same problem with color offset, and have therefore opened the bug again. I have also added some scanned images to help out in fixing the bug, as requested earlier. I am however totally new to bug reporting and Launchpad so the text I first wrote weren't included in my previous comment, and only one attachment was added. Sorry about that.

I will try and upload a few more images (scanned in Kubuntu Hardy Heron with Kooka 0.44) in various resolutions (75, 150, 300, 600 and 1200 dpi). Thanks.

Canon PIXMA backend maintainer, Nicolas Martin, has on Dec 21 2008 committed MP800/MP800R fixes and TPU support to CVS, and flatbed scanning with canon PIXMA MP800/MP800R now works like a charm! Thank you very much Nicolas!
