It sounds like you just need to replace the black cartridge.
If I recall, I believe you can use a 3e or a 6e (longer lasting) BK (black) cartridge in this unit.

Main black print(BCI-3eBK)seems clogged and nozzle check shows only partial pattern. The cartridge seemed to be stuck to the print head. This happened before about two months ago. My technician cleaned it....


Sounds like you need a new printhead, and the only thing you need for cleaning is a damp cloth. All the Canon inks are water soluable. The printheads don't clean very well and don't last long if you do clean them.

3eBk will not print. Canon MP780


Replacing the printhead may work, but it could be a problem with the cleaning assembly. Take out the 3ebk and run a cleaning, if the ink goes away on the pad where the ink cart. goes, then clean assy. is OK, and you need a new printhead.

The printhead is plugged or burned out for the 3EBK. You need a new printhead, QY6-0049-000, around $40.00.

Black ink 3eBk wont print


Ok what you need to do is make sure that the ink cartridge is properly inserted all the way. If it's not then you won't be able to print out black ink at all.

IP5000 3ebk problems


Hi,

I had a similar problem. Pages in blue, but nozzle check in black. Tried what you tried. Changed the ink ($). Still no change. Then tried the maintenance option to clean the bottom plate. And now it is working. Go figure.

PIXMA MP780 printing trouble


If you haven't done so, I would try another new cartridge. It is entirely possible (and occurs frequently) that you got a bad cartridge. Assuming you removed the tape from the cartridge before putting it in, this is generally indicative of either a bad cartridge, bad print head, or that heads or ink tanks may need cleaning.

The Canon support page for this printer is at:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=238&modelid=10444

However, as Canon pages come up as generic pages (without the text I input for you), you will have to type in "missing black ink" (without quotes), to see the material they have posted in this regard. You will find instructions there in regard to how to clean the print heads, etc., if that is necessary. However, I would definitely try another cartridge first, especially if you haven't had that much use on the printer, such that you think these other measures may be necessary.

Please post back if you need further help, otherwise thanks for rating FixYa!
