I am using a Cannon MP830 machine. It very often refuses to print, saying that there is more than one 8C Cyan ink cartridge, which is incorrect. The ink cartridge is a new Cannon cartridge. Is this a defective cartridge, or is it a printer problem? Removing it, and re installing it usually corrects the problem for a brief period. Thank You for the help. Eugene Lane

Hi there,

Error U071 : More than one ink tank of the following color is installed. U071.
Action : Confirm that the ink tanks are installed in the appropriate positions.
The machine will not print if the wrong type of ink tank is used, or if it is installed in the incorrect position.
Be sure to install the ink tanks in the correct order. The proper arrangement from the left is Black (CLI-8BK), Black (PGI-5BK), Yellow (CLI-8Y), Magenta (CLI-8M), Cyan (CLI-8C).

Hope this hepls.

replaced original inks cartize.then restart ur printer.

THE INK CARTRIDGES :
This multifunction printer is compatible with all of the following ink cartridges. Here is a list of these cartridges and how they you can get them:

PGI-5 Pigment Black
CLI-8Bk Black
CLI-8C Cyan
CLI-8M Magenta
CLI-8Y Yellow

All of the ink cartridges are easy to install and/or replace; all you have to do is keep the printer ON, then open the cover it will come in the position and then unlock the cartridge which allows you to remove and replace the cartridge.

These cartridges cost any where between $10 and $15 each. But if you want a good deal, I would suggest purchasing your ink supplies from Costco Wholesale as they provide good prices on packages.

I replaced CLI-8B cartridge for some reason, problem is corrected. I still have print quality problem but  at last now I can use my printer.

Hi,
Your Cyan cartridge is empty and need replacement. Maybe you can clean head of Cyan cartridge with alcohol but symptoms are the empty cartridge!
Good luck.

Hi try to remove ink cartridge and put it back , push down the cartridge to engage will the micro chip.

I have fixed the problem with my MP830 not printing black. It was the print head. I took the print head out and noticed that the black was clogged.

Apparently as the print head uses such fine jets to get the quality levels up, it seems to be quite common for the print head to become clogged.

There are many ways of unclogging the print head, allot of people I read about used alcohol type liquids to clean with, but I was able to get mine unclogged using warm water, a syringe and some good quality paper towel.

Its a tedious process, but you have to unclog all the dried out ink out of the print head. Some people suggested soaking the print head over-night in water or alcohol, but I was too impatient for this method.

There are two small screws which I undid, this allows the print head to come apart and give you better access to clean. using warm water in a syringe(large needle and body-the type used for re-filling cartridges) squirt water into the offending color hole. you should be able to see all the dried ink comming out.

The paper towel is used to bleed the water and ink through the printhead slots.

If anyone is interested in the method which worked for me, feel free to drop me an email and I can offer some more details, maybe would be easier with a few pics too.

I am outta time, kind of hard to explain in a few paragraphs.

My printer was 2 weeks out of warranty when I did this, there was no way I was going to pay a cent more for a new print head thats for sure.

Use this method at your own risk.
