I do not intend to open a cartridge to do so because I think my problem will be worse. I am just continuing to print as long as I have ink into the cartridge (even though the level shown is wrong on my computer) and I will see later on with a new cartridge when it will be time to change it...
I had to remove my ink cartridges and reinstalled them and now, even though my ink cartridges are almost full, levels show low levels. What can I do, to have a kind of a reset of my ink cartrides levels? I have a Canon imagePROGRAF PRO-1000.
