PGI-5 BK not being used?

Aug 17, 2012 11:01 AM

Hi Everyone.

 

I'm printing from ID CS4 to a Canon Pixma MP830 inkjet. After printing more than a dozen 42-page documents, I noticed that one of the two black cartridges, the larger PGI-5 BK, was not decreasing in its resevoir. Meanwhile, the smaller black CLI-8 BK was being consumed.

 

Is this because my print profile is RGB instead of CMYK - or another reason?

 

I have my Canon Color/Intensity preferences set to Manual>Auto (not Photo, Graphic, or None). I have Media Type set to Photo Paper Plus Double Sided & using HP Brochure Glossy paper, 48 lb. My document contains both hi-res photos and graphics.

 

Thanks for helping out. It's killing me not seeing the most economical of the cartidges being consumed. This one is just a little too tricky for me to figure out and I can't seem to find a Canon forum for this question.

 

Paul

    It looks to me like your printer uses a different (pigmented) black for  text only pages, and a dye black for color images.

    But you told it its using Photo Paper which is probably enough to use only the one catridge.

    Pigmented inks don't usually work well on coated papers, so it's propably there for plain paper printing like a FAX
