Question about Canon Pixma MP500 All-In-One InkJet Printer
I replaced the magenta ink tank and got the message that the cartridge was no recognized so bought another new one, CANON OEM, and it still says U043 The following ink tank cannot be recognized I cannot scan either with it locked up like this and the stop/reset button does nothing when I hold it down for several seconds. HELP :(
I had the u043 problem on the blue cartridge on my mp830.
I was using non-original replacement inks but re-using the chips from the originals - replacing the blue cartridge would cause it randomly work but i then noticed the chip holder was not centred so I realigned it and hey presto! the problem was solved first time.

I know this is going to sound foolish or mundane. Did you remove the plastic tape of the back of the ink cartridge? The back of the ink cartridge provides data both to the printer and your computer. If the plastic tape is still there it will block this from happening and register as a error.

Had the problem of transferring the microchip and getting the "failure to recognize" message. Read everything but could NOT get it to work. Finally I compared two cartridges directly and noticed the not working replacement had its chip slightly higher than the good one. It turns out there are two positions where the chip sits flat and you need sharp eyes to pick it. When I relocated the chip, bingo, everything worked.

This is not really a solution as much as a way to temporarily fix the problem. If, like me, you get a U043 message or a U150 message and the cartridge is new or nearly new and still filled , here is what you can do. Go out and buy another ink cartridge, replace the one that will not recognize, place the faulty but still filled cartridge back in the packaging, take your receipt and return the cartridge. If they ask you if there was a problem with the product, tell them, it would not recognize. Like I said not really a solution but at least it will force Canon to pay for their mistake without you having to.

Here is how I fixed the message. I had planned on only using black ink because I was too cheap to buy colored ink also. I removed all of the cartridges and only put in the new black ones. Here was my error message saying that it could not read my new cartridges. For some reason or another, I decided to put all of the cartridges in, including the empty color cartridges..and now it is reading. This may be the case for you, it may not. BUT KEEP YOUR EMPTY COLOR OR BLACK CARTRIDGES JUST IN CASE YOU NEED ALL OF THEM TO MAKE IT WORK!

My mp600 was struck down today (was intermittently doing it, but now permanently) with the Yellow tank doing Error 150.

I have the same problem. I have replaced the cartridge with a new one. That works but it really bothers me to throw away a cartridge that's stil 3/4 full.
The other solution is to open up the top of the printer. When the carriage goes to the change cartridge position reset the bad cartridge. Then you can print and scan. Its only a work around not a final solution but at least you can print and scan then.
Maybe if enough of us return the bad cartridges to the store for a replacement Canon will get the message.

Same problem, with large black ink cartridge a couple years ago. Called Canon the new cartridge did not recognize so I tried another new one and it worked. They apologized and sent me replacement cartridge for free.
Then last week had same problem so I figured printer going bad do bought a new b/w Canon printer on sale and it works great.
Decided to call Canon and they had me try the "Hold Reset" technique but did not work. They then had me put my old cartridge and it still said "not recognized". So Canon agreed printer is likely bad. I asked them what they could do for me since I just spent $50 for a set of cartridges I now can't use. They offered a new cartridge for my new printer and are sending to me.
I have had good experience with Canon. The MP500 lasted me 5 years.

Be careful how you seat the chip onto the new cartridge. Compare it with another that works and make sure it is in identical position. Takes a bit of trial and error, but it's worth it. I pay around 25% for the fake cartridges, the quality of the printing (photos and CD) are beautiful, but you have the hassle of the printer being quite recalcitrant at times

Hi, my mp500 does the same thing randomly, i just open the cover and close it again and it works fine until you want to print something again.

There is a little chip on the front of the original canon ink tank. take this off and stick it onto the "compatible" cartridge in the same place. It wont recognise it as a full cartridge, but it will stop the printer from locking up

Similar problem with my MP5000, just out of its 12 month guarantee. Contacted Canon Tech Support, basically they were not inetrested. Suggested changing ink cartridges, if that did not sort problem to contact a service centre in Luton. Service Centre in Luton want £70 plus, to repair printer, this exlcudes printer head if it needs replacement.
Better off buying a "New" printer, certainly would cost less and at least you have a guarantee, for what it's worth.

After exactly one year of service, this damn Cannon MP530 is doing the same thing. With a brand new Cannon ink cartridge the red ink light won't go on and you can't even print in black only!
Heading to Epson.

After reading this I realised that I'd forgotton to take the mini circuit board from the old ink cart and put it onto the new ink cart.

I had the same problem but luckily I still had my old empty ink cartridge. I took the chip off the from of it and replaced the bad chip with it on the new ink cartridge. I just took a pocket knife and popped it right off and then snapped it on the new one. This worked fine.
If you dont happen to have an old ink cartridge that worked good then I would take it back to the store and tell them the chip on it is defective.

I have the same problem intermitantly. I have replaced the cartridge. That works, but It really bothers me to replace a cartridge that is still 3/4 full.
So what I do is to open up the top of the printer. When the carriage goes to the change cartridge position I lift the bad cartridge up and reseat it.
This is only a work around. It doesn't ultimately fix the problem but you can print and scan. Maybe if enough of us take the cartridges back to the store for a replacement Canon would get the message.

I had the same problem. Apparently, Canon released a "bad batch" of these ink cartridges which causes the error message. It has something to do with the chip on the front of the cartridges.
Contact Canon and encourage them to remove these chips from future cartridges... and stop the price gouging of their customers.

When you move the chip from the empty branded ink cartridge onto the cheaper new unbranded one, also check to make sure the chip is rotated and inserted the right way. If you have multiple ink cartridges check the chip orientation on an adjacent chip cartridge. I had this same error when I did not place the chip in the right orientation and then it worked,

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.

I had the same problem with a Canon Pixma MP800 here is the procedure I went through to fix it. I removed the new cartridge then taking a clean tissue I gently wiped the front of the ink well were the the electronic chip in the cartridge meets the ink head. I replaced the new ink cartridge and the red light came on. I closed the cover the printer returned to normal working mode!
