Question about Canon PIXMA MP530 All-In-One InkJet Printer

6 Answers

Alarm light on, Display indicates error message: Check Ink U150 M

Ink Cartridges are full:
- Magenta tank shows light off - pressed properly/ light goes off
- Alarm light is on, Turn Power on & Off, Alarm light stays on - Printer doesn't print.  
Any ideas how to fix it, before I buy ink cartridges?

    I replaced Cyan cartridge and the warning light continues to blink. Now, the Magenta is also blinking (with a new cartridge) at a fast (3x per 2 secs) and the yellow has started blinking about once every two-three seconds. It too is new.

    The "Ink Low YMC" message is displayed. Ihave replaced all the cartridges, taken the new ones out and reinserted them, turned the machine off and on several times with a half hour "down time." I have also hit the reset button.

    How do I get the lights to stop blinking?

    Alarm light goes on. Magenta cartridge light is off. Cartridge is reseated and light is lit as it should be. When lid is closed, alarm light goes on again and magenta cartridge light is off when checked.

    Cartridge is properly seated, but printer does not seem to recognize it.

    Magenta goes out on mine. I open the cover. The magenta light is off. I pop it out and pop it back in the ink lamp goes on. I close the cover, the printer does its stuff and the "Check Ink U150" message goes on again for M.

  • PKP01 Dec 22, 2007

    Yes, I called Canon Tech support and they sent a new cartridge to fix this problem. Make sure you have warranty on your printer to get free ink cartridge.

    Unfortunately, this "All in one printer" becomes useless, when this problem arises. Because other functions such as scanning and faxing are disabled, even though these two functions do not need ink.

    According to Canon's Tech support, there is no solution, if you have to fax or scan the docs/pics etc. when the chip in ink cartridge fails.

  • Dwyer44 Jan 24, 2008

    Had the same problem (U150 Y), called the Canon Canada number (800-OK-CANON) and they are going to send me a new cartridge. This was not quick and painless however, as the service person first wanted me to go buy a new cartridge myself. Also they need a fax of the receipt which I can't do from home because of the cartridge error. I have to go out and send the fax, which will be processed by Canon in 3-5 business days and then another wait for the delivery time.

    I have the same Problem and I am ready to throw it out the window. I use A LOT of ink and every other cartridge has the same problem. I can not wait for cannon to reimburse me every time and there is no gaurantee that what they send me will work. I am taking it back

    I have the same problem, except it is the cyan cartidge in my case. Before finding this web-site, I had tried most or all of the same things others here have: Remove the cartidge and re-install, at which point the red light goes on, only to go off again just as soon as the printing head moves "back into battery"; clean all the contact points on the cartridge, carrier and printing head, etc., etc.

    So it's the chip in the cartridge. Guess I'll go buy another and keep my fingers crossed...too much down time to wait for a Canon-supplied replacement!

  • Anonymous Feb 06, 2008

    My problem is exactly the same - mainly the small black cartridge and the cyan - pretty soon the cover door will also be broken from being opened and closed sometimes 40 times in a day, with each closure becoming harder and faster - thank goodness for extended warranties!

    U043 error and light on after installing new Canon ink catridges. Previously 2 year old MP530 had worked fine.

    What is fix?


  • Johnny Z Aug 01, 2008

    Wow... I'd say Canon's CLI cartridges are a disaster.  

    I can totally relate to the idiotic error messages.
    By the way, there is SUPPOSED to be a 'clear ink error message' button one can access.  

    According to the User's Guide, when the Stop/Reset button is held down for 5 seconds, the MP530 is supposed to allow the printer to continue printing. However the printer error release button feature does not work as it's supposed to on this machine.

    These printer companies just extort consumers for the outrageous price of ink.  

    Thanks for the links and tips...

    Check Ink U150 - but the cartridge has plenty of ink. Holding down the Stop/Reset button does nothing. 

  • kagoot Sep 18, 2008

    My printer says that it is not allowed to use more than one color ink cartridge per slot--there isn't!!! it said the yellow was out, so we replaced the yellow, now the magenta is blinking and it says that there is more than one color in that cartridge spot, or something to that matter???!!!!

  • crazycanon Dec 30, 2008

    I literally need to open the cover and let the cartridge runs. For my 2-month old printer, it's the black cartridge that the printer cannot detect all the time. When that happens, I need to lift the black cartridge up then put it back in place. After all the hassle, you can finally print the docs.

I added my post today with the same problem, and thought I'd share what I since learned. Apparently this "Alarm light/U150" is common with several Canon models. The U150 indicates a faulty electronic chip (on the ink cartridge). Though I tried cleaning the sensor with isopropyl alcohol, and also tried removing all the cartridges, unplugging the printer for 45 seconds, then reconnecting,etc. as I had read might help, I still had the same frustrating problem. Contacting Canon was the solution that worked for me. First I emailed, but decided I didn't want to wait for their response. A call to Canon Tech Support (1-800-385-2155) was quick and painless. They will more than likely send you a new cartridge, but you'll need to have your serial # & date of purchase handy.

I have a Canon MP530 printer. Alarm light is on. Message on says" Paper Jam, Remove paper." There is no paper jammed. I've spent almost 1hr 30mins trying to find any paper jammed in the rollers, but there's nothing.

I'm so frustrated and am giving up. Please can you guide to a clear solution.

    My Canon MP530 printer says to replace all ink cartridges. I did! The copy, alarm and feed switch lights are on but not blinking. I'm going to chuck this printer and get something more reliable from the thrift store! All I did was replace the ink cartridges with genuine Canon ink cartridges now this. My kids have homework to print. This thing is completly useless. Think Epson.



I just had the error message V130 - check ink cartridge. I held down the stop/reset button for about 5-10 seconds and the problem was solved!

I have had the same problem with my MP530. I called Canon technical support. I do not have my receipt for the printer and don't know the date of my purchase, but they waived the $9.99 technical support fee after I politely asked, "You are going to charge me $10 to help me fix something that's wrong with YOUR product???" I was having the problem with my cyan tank and repeatedly getting the U150 error reading. Apparently the sensor chip is faulty on some of the tanks we buy -- in my case two that I've bought from Staples. The technical support guy is going to have one sent to me from a Canon facility in SC, and says that one should work. But I'm thinking I also need to return the ones I purchased from Staples since they are obviously faulty. And hope that I don't continue to get faulty ones when I replace my ink in the future.

If the ink cartridge sent to me from Canon doesn't work, then I'll call Canon again and take it from there...

Error code U150 The following ink tank cannot be recognized

First, make sure you have the right ink cartridges. Here are the right codes: CLI-8BK and PGI-5BK for black, Yellow - CLI-8Y, Magenta - CLI-8M, Cyan - CLI-8C.

If the ink lamp is off then an ink tank error has occurred. Try to remove the ink tank and re-seat it. Make sure you removed the plastic cover on the ink tank. If nothing helped, you need to replace the faulty ink tank.

I keep getting a U150 ink tank cannot be recognized message. I check the ink tank, it is full. It lghts when I put it in, but when I put the cover down, the light goes out and is not recoginzed.

YES- the solution is I had been sold a cartridge for the printer that was same series 8 it needs but it was PM Magenta not a stand M for magenta so I found out form Canon - this is not a photo printer and it cannot use photo printer ink attached Canon's reply to confirm. Went back 3rd time got the M in the 8 series and all is good alarm light out and no error saying it cannot recognize the ink cartridge. YEAH!!!

Thank you for your reply.

Yes, the PIXMA MP530 only uses the regular ink tanks and not the photo
ones. This is the reason that it did not work correctly. Glad to hear
that everything is working now. If we can be of further assistance with
your PIXMA MP530, please let us know.

Thank you for choosing Canon.

Error code: U150 The following ink tank cannon be recognized (Cyan)

U150 ink error fixed!

I too was getting the error for unrecognized ink cartridge. Then the little green circ board fell out of the end of the ink cartridge and it hit me that maybe if I put in the little green circ board from the old ink cartridge of the same color, then maybe the ink cartridge would be recognized. It worked! So don't throw out an ink cartridge that still has ink just because of that error and hold onto your empty cartridges in case you need the little green/gold circ boards.

This works!

Hey- i just wanted to say that I had the same problem with my MP600. Unlike some people, I have a problem buying ripoff cartridges from a store. I use my printer alot and I simply refill these. You can buy any refill kit and especially with these cartridges, drill a hole near the top and just fill it and plug it. The sponge sucks it up and you're all set. As far as the Chip problem-it is a pain in the ass and the **** at Canon probably won't fix it. HOWEVER, if you still want to print and don't mind that your ink counter says that you are empty simply hold the "STOP/RESET" and the "Black" print button together until it clears and you'll be set. I do it all the time and I know it works on the later MPs. Check it out and stick it to the man
