Canon S800 Photo Printer

I recently took new job which requires me to do a fair amount of printing (work orders). I always print these at draft quality and on the greyscale setting. About the same time I started this job I replaced all 5 ink cartridges with a new 5 color pack. I have not printed a single color image since then. Every single print job has been on the above settings.

This morning as I was printing my work orders for the day, my print job was interupted with a message stating that I was out of photo magenta and magenta. To further piss me off, this message (courtesy of Cannon) took over my system. Clicking the x would not close it and clicking on anything else got the bonk sound. I finally had to use task manager to close the "out of magenta" message.

My question is this, if I've not printed any color at all and only greyscale text, where did my magenta go? (I live by myself by the way, no other users on this system). And second, why is it that with a nearly full cartridge of black ink was I forced to make a trip to the store to buy magenta and photo magenta cartridges just so I could finish printing my black text with my freaking half full black cartridge?

It's like Kinko's saying "sorry, we're all out of red paper. We will not be able to print on white paper until we get more red paper".

Ridiculous! What is up with this?

Yup, composite black uses a lot of red. If your text is actually images (PDF or other image files like jpg) rather than true text (like direct from Word (.doc), Open Office, or Notepad,Canon printers will use composite black. Try it in normal mode rather than Grayscale to see if more actual black is used.

also make sure youre printing setting is set to plain paper, even if its something else. the plain paper setting will ensure the printer doesnt use a colormix for black text

zig probably has it. The "regular" black ink is no good on photo paper, and the printers hence don't use it unless the paper type is a non-photo material. Likewise probably when the document type is set to Photo or somesuch, not Auto.

Besides, every time the printer (any printer in fact) runs a cleaning cycle, ink is consumed - so even ink you haven't been using at all will run low after a while.

The S800 is a six tank printer and doesn't have pigmented black, it only has dye black which works fine on photo paper but usually doesn't look as crisp as pigmented black for text on plain paper. No real excuse for not using at least some of that when black is called for in any mode on that printer - it's just another Canon "duh" moment...

In fact, the OP wasn't about "my black isn't being used" but "my blue's empty, how come" ;)

If you're printing greyscales, lighter shades of grey don't actually look good if you're using sparse black dots. Good printer drivers sprinkle the lighter colors evenly to give the impression of grey, but up close it's all color and no black. This is true for all kinds of grey and color mixing actually. Black only comes in very near maximum saturation.
