The U043 error code indicates that an ink tank is not installed. One or more ink tank icons on the LCD should also be lit up. The lit up icon indicates the applicable ink tank. Verify these tanks are indeed fully seated in the print head and that they are lit up red.

You can also press the OK button to clear this message and continue.

MP500 ink tank cannot be recognized error U043

I had the same problem. My mp630 is also only 4 months old. I replaced all colour ink cartrdiges(inc black), but was only able to release the function for detecting the ink levels for magenta and cyan. Yellow and black then started giving error message U043, with them alternating between working, but never working at the same time. Getting them all clicked in with the lights glowing red does not solve the problem, as once the printer cover is closed, the same error message turns up. The only thing that worked for me is moving the chip slightly out of alignment, by pushing the sliding chip holder, and I only had to do this twice before they all started working and the printer was unlocked.

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

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.

MP500 ink tank cannot be recognized error U043

I have a canon mp510 pixma same message U043 and a u150 fault.
I cant see any chip to replace and have replaced my original cartridges with a non branded cheaper type, this might be why. Does this make a difference or is this the same problem occurring with replacement canon cartridges as well.

Dont want to buy genuine ones if its not going to make any difference.

Anyone who can help me would be appreciated
