Canon MP250 Series Color Management for Adobe Illustrator

Hi guys,
I am using the U.S. Web Coated (SWOP) v2 color profile for my CMYK artworks. I also use Canon MP258 inkjet printer to preview my artworks. The CMYK profiles brought no problems for my commercial printers where my artworks prints just as I designed but when printed using the MP258 the color was not as it should be. It does look like it but when zoomed to pixels the color was actually different. I mean 100 Cyan or 100 Yellow or even 100 K was printed with mix of colors.
Standard color profile for the printed is sRGB IEC61966-2.1 as same as my monitor.
I tried to change the printer color profile to Canon MP250 series MP2 profile which results a better color prints but they are still mixed even for the 100 Cyan.

Refer the attached image.

Does anybody have solution for this.
