The 3ebk nozzle check shows problems and prinitng is blurred

If you open the preferences option for your printer there should be a maintenance tab with easy options for cleaning and checking the results. The alternative is to use the menu directly on the printer: 1. Press Menu twice to show "2. Maintenance" 2. The first option is NOZZLE CHECK 3. Press OK This should give you a print showing the current state of each colour. If there are any missing lines in 3eBK or lines in any colours then perform the head cleaning below. 1. Press Menu twice to show "2. Maintenance" 2. Press + to show "CLEANING" 3. Press OK Repeat the nozzle check after each clean. If not improved after three attempts try a deep clean as below (cleaning uses up ink) 1. Press Menu twice to show "2. Maintenance" 2. Press + twice to show "HEAD REFRESHING" 3. Press OK Repeat the nozzle check. If still not printing correctly there are various external solutions available to clean the print head such as http://www.printheadhospital.co.uk/canon-hp-printhead-cleaning-kit.html

The nozzles are block, this is cause be periods on non use. The print head needs replacing, but it may be expensive.
It may be more cost to buy a later model and better printer than replace the print head.

you need to run the nozzle deep cleaning utility, nozzle check and alignment procedure under the printer properties maintenance tab.
Please rate this solution. Thanks.

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.

Check if there is a tape over the top vent intended to let air into the ink tank and so ink can flow out to the writing head.

Yes that's typical when the printhead goes bad. You need QY6-0064-000 around $60.00

Are you using OEM cartridges or reloads? Sometimes the reloaded cartridges gum up the nozzles especially the black ink. If you have not tried an OEM black cartridge I woud try it.

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.

That's a BCI-3eBK cartridge. Most Canon inkjet problems can be resolved by replacing the print head. eBay is the best place to find a replacement.
