Some inkjets don't keep the heads "sealed" when powered-on, and they'll clog much more quickly than when turned off.

Wish I knew if there was a way to find out about that for this specific (canon s820) printer.


It appears as though that's the case for my Canon s820. I left it turned on for months, and I had printing problems where certain colors wouldn't print. Now, I leave it off most of the time and I don't have those problems any more.

HOWEVER... and this is the reason I'm digging up this old thread...

It seems to consume colored ink voraciously, even when I'm not printing any color documents. I just went through an entire set of brand new color ink cartridges after only having printed black text. In fact, the color cartridges reported empty well before the black cartridge even got low.

Does anyone know why an inkjet printer might consume color ink in that way?
