Question about Canon PIXMA MX870 Wireless Office All-in-One InkJet Printer

Open Question

Despite changing ink cartridges, I consistently get a U043, "cannot recognize this ink tank" error message on my PIXMA MP870 printer. The particular cartridge is the middle one (yellow). It is the only cartridge slot for which I receive this error message.

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: Canon Pixma MP950 Ink Refill Error

replace the cartridge with a Canon as the chip has gone on the cartridge.

this is the only way around it with the mp950.

This is to stop them being refilled

I have this Canon MP600 using unchipped cartridges. Once you have changed the chip over onto the catridge and inseted it should stop flashing which indicates the cartridge is located. The printer will not tell you the level of ink until you run out. When changing the chip over from original cartridge onto unchipped ensure it is not damaged and fitting properly other wise the error sign will show.The printer should print without any problems, i know you can not disable the ink monitoring system. Hope this is some help Mr T

SOURCE: getting error U043

Hi,

The little chips on the front of the cartridge create a trouble for people trying to refill the cartridge, as of right now, there is no way to easily reset the chips. If you refill them, they still register as empty, and therefore don't work.

If the following tips doesn’t help, you can try to install the original new ink cartridge following the instructions in the user manual. This can solve the problem.
Note :
Be sure to install the ink tanks in the correct order indicated by the label on the Print Head Holder. The machine will not print if an ink tank is installed in the incorrect position.
For information on the compatible ink tanks, refer to the back cover of the Quick Start Guide.
Tips before Replacing Ink Tanks : Important:
- To maintain optimal printing quality, we recommend the use of specified Canon brand ink tanks.
Refilling ink is not recommended.

- Once you remove an ink tank, replace it immediately. Do not leave the machine with ink tanks removed.
- Replace empty tanks with new ones. Inserting partially used ink tanks may cause the nozzles to clog. Furthermore, with such tanks, the machine will not be able to inform you when to replace the tanks properly.
- Once an ink tank has been installed, do not remove it from the machine and leave it out in the open. This will cause the ink tank to dry out, and the machine may not operate properly when it is reinstalled. To maintain optimal printing quality, use an ink tank within six months of first use.
- Color ink may be consumed even when printing a black-and-white document or when black-and-white printing is specified.
Color ink is also consumed in Print Head Cleaning and Print Head Deep Cleaning, which may be necessary to maintain the machine's performance. When an ink tank is out of ink, replace it immediately with a new one.

After replacing ink tank;
Turn off the machine, and unplug the power cord of the machine from the power supply. After five minutes or more, plug the power cord of the machine back in, and then turn on the machine.

If you would like to vote for the answer, this will help the others to see the similar problems solved and also will be a satisfaction factor for me to continue helping you.
All the best.

U043


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.

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
