U150 error

Getting a message saying I have two magenta tanks installed, I'm on the phone with Canon now, they are going to waive the $9.95 tech support call and send me a new tank.

In the meantime if I have a print job he said to I'd need to purchase a replacement tank. He also assured me it's probably a chip problem within the tank itself, nothing more.

3 year old printer, my second Cannon. 2 Cannon camera's...all is good.

Things break.

Good response from Cannon tech...

this happened one time before as the alert light came on shut off printer and restarted and it fixed the problem but now doing that won't work. Going to try the wetting suggestion and see what happens as this ink catridge is 90% full....

u150 Magenta has gone out on my MP600 and of course its out of warranty. Jeez, this sucks.

we have once used compatible ink and that didn;t work so we bought new original one but still it doesn;t pick one or the other ink tank we kept on buying the new one but still no good

i have an MP830 i get the U150 on the 1st balck cartrige... power cycle use to work.. but now no more.. wat it the wetting agent that is mentioned earlier? maybe the contacts need cleaning..??

ip6700d same u150 error for magenta (pm).

If I remove all ink cartrides and add back 1 by 1. I get error u043 untill I get to my problem cartridge. Then I get u150.
If I swap with any other ink cartridge I still get the same error. So this appears linked to the printer itself instead or just being an ink cartirdge issue!

Yea. My Cyan is reported as having two of them in the unit. Same original cartridges in my IP6700D. I can open top, wait for the cartridges to light up, close top and then open and close it about 3 to 6 times and it will print whatever. Seems to help if I scream obsenities. I'm going to use up the cartridges and throw this piece of S*** away. I have always liked epson ink jets before and thought I'd try this one. Going to go back to epson.

IP6700D. Started with internittent error - "2 yellow tanks installed". Cured several times by power cycle. Now U150 "yellow tank not recognised". So Canon think I've gone from 2 yellow tanks to zero without replacing any of the tanks. A neat trick! Now can't print documents I need for a business trip tomorrow. Awaiting Canon help-desk reply. Having seen the number of posts with the same fault I refuse to waste money on replacement tanks until Canon can offer a solution. Cheaper in the long run to buy a non-Canon replacement printer.

I had the same problem with U071 error telling me that there was more than one black cartridge installed. The first few times this happened it fixed it by removing and re seating the catridge, then that no longer helped after several times. I tried the wetting solution and bingo! it worked (so far).
Lets hope it stays that way.

I just bought this printer in Dec of 07 and now am having this U150 error. It's driving me mad and it's too late to return the thing. I bought a couple replacement cartridges and it seems it's getting worse in a shorter period of time after putting the new ink in. Now we are trying to get homework out, science fair project and I will NEVER buy a Canon product again. AND I don't have money in the budget for another printer or scanner right now. I have never had an issue like this before and thought installing an updated driver would solve the problem. I would think Canon wouldn't have ridiculous problems like this....afterall......they aren't exactly new to this. This is more than frustrating......

two tanks of same color installed. I have an MP830 and it constantly tells me I have two #5 tanks installed. That's the LARGE one and you couldn't get two of them in with a hammer!!! Speaking of which, I may just use a hammer on this worthless pile of junk before I return it to Best buy and demand my money back! This piece of **** won't even let me print!!!

i printed 15 pages and got this U 150 error... crappy printer.. Canon.. never again

Same problem here with Canon Pixma MX700 bought just before Christmas 2007. I haven't printed a lot on it so the U150 error on the Black cartridge is really pissing me off. I checked the tank and it's still half full. I take it out and reseat it and the red light comes back on. 
Then I close the printer cover and I still get the U150 error and the red light on the black cartridge is off.
Seems Canon has some duds with this design. Back to the engineering drawing board guys.

Message says "U071 More than one ink tank of the following color is installed. Bk"
Message shown is not the case. I have tried taking out all ink tanks and then put them in again which worked a couple of times, although not now.
This is the second time I will have to go out and get a new tanks. Last time was because the machine suddenly decided to stop recognizing the Cyan cartridge!!
Rubbish and really annoying...

Bought my Canon MP830 in Novemeber 2007, and within 2 weeks I was getting the "U150 Following ink tank cannot be recognized" for the yellow ink tank. Canon sent me a replacement yellow ink cartridge.

Now, after inserting brand new tanks for black, magenta, and cyan (they just ran out), I am getting the same error for the large black tank.

In the past, I've had some false alarms with the magnenta and cyan tanks, but popping the ink cartridges out and then re-inserting them eventually solved the problem, but this is a real pain.

I am spending too much money on replacment tanks for them not to work, and the printer ends up with lots of down time due to seemingly faulty ink tanks.

This unit does not deserve to be recommended by Consumer Report.

same problem but with black.

error message says more than one copy of the same colour is installed Black5

get it in yellow tank: U150
model mp600
how stupid : yellow ink problem, and cannot print black and white, nor scan a document - Probably this was my last canon device

I have the same problem with my Canon iP6600. No solution at all. This is the second NEW tank of Cyan ink that I throw away!!!

ditto, happened with my magenta tank. Turning printer off worked for awhile but now I will have to go out and buy a new tank too. Canon - you owe us one! Otherwise, I've really liked this printer.

U150 on the Photo cyan cartridge... Never used the printer for photos... ARGHHHHHHHHHHH on the Pixma IP6700D
