The result is the same when I use a different (also Vista) computer. Whether I print or copy, the result is the same: blank pages. It means there may still be some clogs stick to the printhead.I have a Canon MX870 printer which I have connected to a Windows Vista laptop via a USB connection. But, if you're not using a full nozzle, you can see there's black. You got a pretty good print out except you can see a little bit here. Those two colors are okay, and you can see at the full nozzle where it is, but every nozzle is firing. For example, this is one of the cartridges that I unclogged yesterday.

CMM is the same as yellow, so I hope you understand now what this means. You can say it is if you mixed CMY, you have a different black than the natural black. This black they're mixed, they're mixed black. But, when only some of the nozzles are firing, you may see the clogging. If you have all the nozzles firing and that the clog may be here. When you have a clog, the clog might not be shown. I have a conversation with Canon for an hour. This is some part of the nozzle that is firing. You're going to think this Y is the all the nozzles are firing. Level I mean is several dots printed on a Page. This is 100% level, and Canon will not tell me what level this is, but I suspect it is about 70% or 80%. Then for each color, Canon prints at two levels. The Canon print from the black cartridge itself, which shows you if the black is clogged.

For the black, the Canon doesn't need to test the mixing. That's why you have the grayish black next to each of CMY color. When you print pictures, the printer is trying to use those three colors to paint a picture. This is because the pigment is not great in printing pictures. Yet, if you print a photo, even if it's black in color, the printer combines the three CMY colors. If you print a document and in black, the printer will use black to print a copy. The cartridge is a tri-color cartridge (CMY). One is black, has a pigment ink (or you converted to the dyeing already), and then you had another cartridge. What happens is you would have two cartridges. Today we're going to talk about how to read a nozzle check pattern from Canon.
