Question about Canon PIXMA MP830 All-In-One InkJet Printer

Ink Cartridge Error PIXMA MP830.

I replaced the Magenta cartridge when it ran out using a Canon 4ink tank package. This worked fine. A few days later the Black8, Cyan8 and Yellow 8 ran out. When I replaced them I now get various messages. Sometimes it says U043 that the Black Yellow and Cyan cannot be recognized. Other times it says that all four cannot be recognized, then it says that I have duplicate cartridges installed. I have clicked the cartridges out and pushed them back in. Sometimes the red light goes on for a few seconds then it goes off. Occassionally one or two of the lights blink and then stay on for a few seconds and then go off. As expensive as these cartridges are, I am hesitant to just try another box. Any suggestions you may have would be greatly appreciated.

    I received the same error code (U150) several weeks after I purchased the printer. Strangley it worked for awhile but then began giving me this error code. I will try to replace the cartridge and see if the printer works.

    My almost new printer now thinks that it has two magenta cartridges installed. Popping them out and back in again sometimes fixes the problem. Sometimes we have to repeat the process 10 times!

    I keep running into the same problem - error U150 and it's always cartridge #5. I have also run into the duplicate cartridge error problems. I keep taking it out and putting it back in - sometimes that fixes it but must often I have to return the cartridge. What a pain! I buy the ink at Costco and have learned to keep my receipts. I should've bought the HP!

    Cartridges aren't recognized. Printer gives confusing and wrong messages. about the cartridges. Like 'cannot read the ink level'. That sets of an alarm. At my windows pc I can bypas the alarm and continue printing with a non-functioning cartridge.
    At my Mac I get stuck altogether. I can't even scan or fax anymore.

    I don't think the issue is with the printer. I think the issue is with the ink cartridges. I love my printer and I have had it and used it TONS for almost 2 yrs now. This issue just started this week after purchasing a new Yellow ink cartridge. I don't have the issue anywhere else. And it recognizes if I have the wrong cartridge in. It's frustrating since I need this paper printed out, but I'm glad it isn't my printer.

Aligning the cartridge has nothing to do with the problem of the u150 error that two of the same ink tank cartridges are installed. It's a defective chip in the ink cartridge, as soon as I placed a new cartridge in it worked like a charm. HOLD ON TO YOUR INK CARTRIDGE RECEIPTS, because if this happens to you and the cartridge is obviously new....the store of purchase should provide you with a replacement (+ if you don't want to make a 2nd trip, some stores have the mp830 on display and you can have them toss the cartridge in and check to make sure the chip is working properly). IF THE STORE WON'T REPLACE THE DEFECTIVE CARTRIDGE, contact CANON (USA 1-800-828-4040)and explain the problem & hopefully the will stand behind their product and replace the defective cartridge.

I have a U043 saying the cyan ink cannot be recognized after I was trying to replace it with a new one. I did accidently put the blue on there & the cyan in the blue than the printer did not recognize both at first, but after I switched it, the blue was recognized and the cyan still did not work. Than I had went back to return the new cartridge at the store with another one and it still did not work with the new one. Do I need to clean the cyan area? And how?

HI. Try holding the reset button for 6 seconds to overide the error. This may dissable the chip so it won't report but will allow you to keep printing. Simply check the ink tanks visually.

Refilling will give the same error too, again dissable the error.

SOURCE: Error U043 - Ink Tank Cannot be recognized

Try to open and close the main cover a bit, ... ink recognition will start and may solve the probleme ...
... otherwise remove the cartridge and clean the chip contacts e.g. with spirit
Maybe also pressing the stop/reset-button for >10s will also help to continue printing, but in this case the fill level of the cartridge will no longer be shown

SOURCE: MP500 ink tank cannot be recognized error U043

Same problem - two solutions I found helped me work out mine. One said contacts needed to be cleaned and it worked to use a Q-tip and alcohol or just click it in position several times until it recognizes the cartridge - this may work. Another said that they got it to work by installing a brand new cartridge - cool, but I have one full of ink it won't recognize. So I pulled the little circuit board off a used cartridge (like you need to do with some refills) and put it on the cartridge that it wouldn't recogrnize - works great. Still haven't figured out how to get it to acknowledge ink levels though. Canon really should be more consumer friendly since these problems seem to be intended to compel the use of proprietary cartridges.

Need to replace ink cartridge

Replacing the five ink tanks (cyan, yellow, magenta, black dye, and black pigment) is a simple task. The top of the printer flips up to reveal the ink tanks and the printheads, and by flipping a lever, you can pull out each tank individually. Being able to replace individual tanks is a boon, as you won't waste colors you use less frequently. Also, you won't need separate photo ink to print photos, which we appreciate. Canon ships the Pixma MP830 with full ink tanks. Replacement color and dye-based black ink tanks cost $14.25 apiece, while the pigment-based black ink tank costs $16.25. Canon estimates the cost per page for both black text and color text to be an inexpensive 2 cents.

Printing color copies

check to see which cartridge you put in, photo magenta cartridges DO NOT work in the MP830. sounds silly but we see it all the time.

check to see if the short vertical black bar next to the magenta pattern looks ok, not brown or gray or streaky. if it is you may need a professional head flush, take the whole printer in for service.

U150 canon pixma MP830 "the following inktank can not be recognized" magenta. Please help, Thanks, Ted

I have had this problem repeatedly lately. To try the Stop/Reset solution already mentioned, I turned on my infrequently used Canon Pixma MP830. Most of the time at a fresh startup it gives an alarm message "the following ink tank cannot be recognized" OR "there are two of the following ink tanks installed" ??! for the single black 8 cartridge !, a Canon original. Of course, tonight it started just fine, but the methods I have used when it does not work because of these alarms are the following:

I open the top, wait for the cartridge carrier to center, unsnap the black 8 cartridge, then snap it back in and close the top. This sometimes works if repeated until the machine recognizes it. Sometimes I unsnap all the cartridges and resnap them. If this doesn't work, I remove the black 8 entirely and use a clean cloth to wipe the electrical contacts of the cartridge in the direction of their length and reinstall. It sometimes takes a repeated combination of these steps and sometimes the two different alarm messages will appear alternately. There does not appear to be any logic to it. Once the machine does recognize it, it works just fine.

However, if the machine is turned off, many times when it is turned back on later I have to go through all this frustrating rigamarole again. I hope it is a glitch with this particular cartridge (fairly new) and not the machine. Next time I get the alarm messages I will definitely first try the Stop/Reset button solution suggestion, but I thought I'd add my two cents solution, which so far has eventually caused the machine to recognize the cartridge.

Cannot recognize ink cartridge

I had the same problem. I was using original brand cartridges and it was still not working. Here's how I got it to work. I recommend doing each step and then trying to print a test page to see if it is working.

1. I used a Q-tip with Isopropyl Alcohol and cleaned the gold contacts on both the cartridge and the mating contacts in the printer.

2. Then from the Setup Menu, I found a menu called Tools. From there I ran "Align Print Cartridges".

3. From the same menu I also ran "Clean Print Cartridges"

4. I then ran a few test prints by going into the Setup Menu and then choosing "Print Report" and then selecting "Self-Test Report". It prints grid patterns in black & white as well as magenta, yellow and blue. The black grid pattern had some missing lines until I printed this report a few times.

5. I made a few photocopies and now the printouts no longer have large stripes of missing ink as it did in the earlier steps.

Good luck. Hope this helps.

Frequent problems with the magenta cartridge of my PIXMA MP510.

Dirty or faulty contacts in the cartridge chamber is the only logical explanation.
Remove the cart and with a cotton wool bud and a little alcohol or similar[NOT ACTETONE it melts plastic] give a gentle clean.
