You have a defective ink cartridge, usually the one whose light doesn't light when the carriage comes to the center position.

UO43 error there is no ink cartridge there, but when there is an ink catridge UO71 it says more than one ink cartridge


Hi there

For troubleshooting purposes,
Perform the following:

1. Open the printer and remove all ink tanks.

2. Insert a single ink tank in the printer then close the cover.

3. Confirm whether the printer recognizes the installed tank
properly. If it does, it will indicate it does not detect the other ink tanks, as
they are not currently installed in the printer.

4. Repeat steps 1-3 with another ink tank.

5. If the printer at any time indicates two of the same ink tanks are
installed, the cause will be the last tank installed. For example, if
you inserted an ink tank earlier, and you later inserted another ink
tank, and it said two of the same inks were installed, the cause of
the issue is the last ink tank.



Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

Getting a UO71 code saying more than one ink tank is installed. The ink tank is full


Thats a defective cartridge, you need to replace the one whose light is out when they come to the center. Canon will replace defective cartridges for 30 days after purchase.

Alarm: UO71 more that none ink tank...


That means that you either have a defective ink tank, or there are two of the same color installed, check the label for the inks, the one that flashes is the one with a problem.

When installing or replacing an ink tank, only one of the ink tanks should be installed. If the ink tank is not installed correctly, an error message will display.Press on the tab to release the ink tank, then remove it from its slot. If you are replacing multiple ink tanks, make sure to replace one by one.
Give a thorough check up to confirm any colour ink is not twice loaded (cannot be loaded in a single slot,may be in another slot )
May be any defective ink cartridges

Hello there scubadave,

I've gotten in touch with Canon and have somethinga little different to try. At the very least the error should change.(Sorry, gallows humor). Please read this entire response before takingaction.

After the upcoming test procedure, I have included alink and procedure to contact Canon tech support. The assure me theywill replace any faulty tanks.

The purpose of this exercise iseither rule out ink tanks that are behaving or isolate the one(s)responsible for the dupliucate error. You should write down the results of thistest. Please perform the following:

1. Open the printer and remove all ink tanks.

2. Insert a single ink tank in the printer then close the cover.

3.Confirm whether the printer recognizes the installed tank properly. Ifit does, it will indicate it does not detect the other ink tanks, asthey are not currently installed in the printer.

4. Repeat steps 1-3 with another ink tank.

5.If the printer at any time indicates two of the same ink tanks areinstalled, the cause will be the last tank installed. For example, ifyou inserted an ink tank earlier, and you later inserted another inktank, and it said two of the same inks were installed, the cause of theissue is the last ink tank.

Youwill also need to list what inks are being used in the printer. Statethe type of ink that is being used and the order that the tanks areinstalled in the print head.
Provide the exact part number (such as BCI-6C, BCI3eBk, etc.) if possible.

The Canon support rep assured me they will be glad to replace the malfunctioning tank(s) for you at no cost. Please

They responded quickly, professionally and apologetically. They want to help get this resolved for you.

My printer won't print because there is more than one inktank of the same colour


There are 2 types of black cartridge, CLI-8Bk Black Ink Tank & PGI-5 Pigment Black Ink Tank. These must be installed in the correct order as below. Have you replaced a black cartridge & perhaps used a different type?
