I found this site because I too am having trouble with my Canon printer. I have the PIXMA iP5000 and can NOT get it to print magenta or any shade of red. Only pinks and orange. I have cleaned, removed the print head and cleaned them, used canon inks etc. I just can not figure it out. The red (magenta) has always had an issue with clogging but now won't print the correct tone.
Poppy...I noticed your test pattern sheet and mine doesn't print up like that. Mine won't show the lower 6M bar. Also the side bars next to the ink ref numbers that are grey in yours...are green in mine. I also do not have any of the lower test bars that you show but that could be because of the models being different.
I am ready to take a hammer to this thing! It is really frustrating.
