When I print a test patterns, the black graph only prints half, it cuts through the middle of where it says 3eBK. Also, when I print black and white documents, sentences are missing and cut in half

It sounds like your black (K) or Black/Yellow (KY) head needs to be replaced.
The problem appears to be in the top half of the black head.
Without knowing more (like what make/model the printer is) I can't help more than that.

you might have printer set to print in black ink only check in settings if not re install printer driver then print test page if the windows logo comes out in colour and the text black everything is fine

adjust print heads... in the printer attributes by right clicking the printer the attributes should show a tool window the do this

then check if you have ink...

also check to see if you have your print set to a heaver weight paper. this could make the paper move while its printing

When elements on the printhead burn out, that's what it looks like.You need a new printhead, QY6-0057-000, around $50.00

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.

Both blacks are in your print driver test pattern?
Go into the maintence menu and choose nozzle check.
It should rint a test pattern with the first grid being labled "PGB" if not your head is clogged.You can tru a solution of 20-25% ammonia to water and soak the black print head for a half an hour.Then completely dry the electrical contacts and re-install.
If that does not do it I have a more aggressive solution that requires a baster.

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.

First of all... have you tampered with the printer's firmware? If not, it's unlikely it became corrupted. But if replacing the ink cartridges with fresh ones, and using a new print head did not fix your problem, you may be out of luck.

Is this a new problem, or has it always been like this?

Could it be that the print driver is always printing photo? In that case, it uses the narrow black ink cartridge instead of the fat 3eBK cart. You should print a nozzle check pattern and verify that you see the 3eBK cartridge pattern. If you do, the problem is likely SOFTWARE... your driver settings, not the printer itself.

I hope this helps.

Useually if your printing has lines through it it means that the head (where the ink comes out ) is had it & your up for another head. Sorry but useally big bucks I hope it's still under warranty

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.
