Okay, so here's the thing... I have a Pixma Pro9000 II, which I have been using for about two years now, and for the same two years I have been repeatedly and increasingly frustrated with its ink usage until I have to hold myself back from throwing the POS out of the window (such as today).
I KNOW I put in brand new cartridges a month ago, and in this interval, I printed maybe 50 black and white pages of text at low quality, and maybe a handful of photos. Now this thing is telling me I'm out of cyan and magenta. WTF?! All other ink levels are more or less full.
Now look, I did not print a handful of cyan and magenta posters this month. We're talking 4x6 balanced exposures here. This sort of random ink depletion happens with other random colors too. In fact, I don't even need to print to see the ink levels drop before my eyes. All I have to do is turn the printer on and off, and the ink is visibly lower than seconds prior! Some drop, while others remain. Tomorrow, when I turn in on, it's probably going to tell me that I'm running low on red, although today it's full.
It costs me around $80 to fill this piece of sheisse up with ink each time, so I'm sure you understand my frustration.
Based on my observations, I have arrived at the following hypotheses:
1. Every time the printer does its stupid buzzing and clicking cleaning cycle, it actually sprays geysers of color like Ron Jeremy after eating a kilo of Skittles.
2. My printer heads may dry out periodically because of low humidity or something, and the printer decides to flush the contents of its cartridges to get anything through.
3. The ink evaporates.
4. Canon deliberately programmed this thing to engage in ink wasting cycles other than printing my photography or timed the cartridges to deplete after a certain period of time.
I'm curious if anyone in this community has ever experienced anything of the sort, and what you have done to remedy this.
