    When I go to print I get the message 'more than one ink tank of the following colour is installed. Black (5). Use only one ink tank per colour at a time.' I have to click the cancel printing button.

    I turn the printer off. Turn on again - then open the lid to see the Black (5) ink is flashing - so I remove it and then put it back then close and go to print and it works OK.

    I have had the same issue for the past two weeks. It is very annoying.

    I've had a Canon mp500 printer-copier-scanner for a few years and it's been flawless, until the last couple of weeks. Now I'm getting an error message saying there's more than one ink cartridge of a specific ink color installed, and it won't print. I have to "cancel" the print job. There is of course only one cartridge of each ink color installed, and none of them needs replacing. Any ideas, anyone?

    I'm having the same problem. It is very irritating. I have had some success with taking the cyan tank out and putting it back in but not always.

After reading the suggestions here, I tried cleaning the contacts of the cartridge with a Q-tip cotton swab, SLIGHTLY dampened with rubbing alcohol. This seemed to pretty much stop the problem, though it did re-occur occasionally throughout the life of that cartridge. Once I replaced that cartridge, it has never happened again. I guess this shows that you can (rarely) get a cartridge with bad contacts. If this ever happens again, I would return the cartridge to the retailer and get a new one.

I am having the same problem. I found a few other forums on this issue that suggest cleaning the contacts on the cartridge. Opening the cover and reseating the cartridge only worked the first few times for me and now even cleaning the cartridge fails. Only other thing is to replace the cartridge all together I guess.

Error code U071 , more than one ink tank of te following color is installed, is the message on the screen. This is not the case as each cartridge is different and correctly installed?

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.


Error 6502 is a ink tank position error, one of the contacts for the ink tank in the carriage could be bad, or simply a wrong cartridge installed. You can't use photo magenta in a magenta slot, or photo cyan in a cyan slot.

Ink tank error message Canon iP3500

Sorry this isn't a solution but I'm having the same problem. Even if I exchange the colors, it's always the cyan no matter what slot it's in!?!?! Not the slot.

Can I turn that color OFF???

Check ink U071 cyan

Are you using genuine ink cartridges? If not, then perhaps there is no microchip on your ink cartridge. You can take the old chip off your used cartridge and put it on this cartridge and see if this solves your problem.

I have Canon M560 printer installed 8 months ago. I replaced the CLI 221 Magenta and CLI221 Cyan ink cartridges, won't work and got this message Error 1411.

Canon MP830

From time to time my MP830 shows the same problem ... just opening the main tray and closing it again restarts the ink test after which in most times the problem is solved.
If after two tries the error message is still present I remove and replace the related ink cartridges.
By now I could remove the error message in each case

Inaccurate error message

mine does it with the cyan and it worked for awhile...if I take a cartridge from another ip42000 cyan, it works. Any ideas?

Misreads ink tanks: says full ones are empty and there are 2 cyans, etc.

I had the same problem -- error message saying two cyan print tanks installed. Nothing helped (including disconnecting power cord). Then found I had an older cyan print tank still in its pack on hand, Installed that. No further problems. Assume this means print tank giving error is part of a faulty batch so am returning to retailer for refund from Canon.

Canon ink tank problems

I think I figured this B!tch out.

When you get the error:
"More than one ink tank of the following color is installed" or
"Ink cartridge not recognized"

Open up the lid where the cartridges are and hold done the "SEARCH" button. This has been working for me, and I bought my ip6600d in 2005, so my machine is old, and ready for this..........ORIGINAL INK!!! Never really used it beyond printing very few pics. So I was really pissed when I found these messages to almost 5 years after buying this printer. So to recap, open the lid where the ink cartridges are while holding the "SEARCH" button, hold it up for like 5 to 10 seconds, place lid down still holding the search button, then let go of the search button. I did notice the alarm was lit, but went away after I released the search button. Good Luck!!!

Until I held the search button down I had turned of the printer, reseeded the cartridges and open and closed the lid but it never worked.
