Reset printers and cartridge.
Printers problem solving,tips, tricks and tutorial.
Where do I find the cartridge?
I replaced all ink carts with OEM, cleaned printhead and check'd elec contacts--still getting U043 code
When I removed the ink tanks in response to this code, found that there was an accumulation of ink on the contacts in the print cartridge, which I assume was short circuiting the chip reader. When I cleaned out this ink using 3 or 4 cotton tips, the error message stopped.
Check the actual pins on the front of the cartridge carrier, they might be bent. If so, ever so slightly bend them back to the original position. If they are broken, contact Canon. You'll probably be buying a new printer.
I have the same problem on a Canon MP830. I've replaced the print head four times. I've cleaned the print heads with contact cleaner. I've cleaned the tanks contacts. I've cleaned the contacts in the printer where the tanks contacts make contact and it still won't work. What's next other than throwing the whole thing in the garbage? Can I replace the logic board for cheap?
Hi Alm1ghty55,Have you replaced the cartridges ?
Reread what I just posted then post something that I can use. Your saying all five tanks have failed simultaneously! I highly doubt that. These tanks were brand new. After two weeks of usage suddenly the printer stopped seeing all five tanks. The next step is replace the logic board.
