My Canon MP830 has been working fine. All of a sudden, it is displaying the error message UO43. I only use Canon ink cartridges. I've rebooted the printer, removed & re-installed all the cartridges more than once. I still get the same message w/o any cartridges in the printer. What's next? Thanks

I'm having the same problem with a Pixma 892. We were in the middle of printing something last night and the computer turned off. We unplugged it and turned it back on and now have the error message UO43. I followed the procedures listed below to reseat the print head but still get the same message. Tried that twice. Please advise. Thanks.

If reseating the ink tanks and print head, as well as resetting the printer did not resolve the error, the printer will require servicing. Please call or email us at one of the methods on the Contact Us page to obtain your servicing options.

I had this error code when I installed a new genuine cartridge.
I noticed that the red light didn't come on on the cartridge that the printer did not recognize.
After some faffing, I realised that the light came on only sometimes. it was erratic.
Using compressed air with a straw, I angled the straw and blew air along the contacts. I did it a bit blindly, but I knew roughly where I was aiming. I then used some brake cleaner on a tissue (any cleaning solvent will do, alcohol, contact cleaner, nail varnish remover) and gently rubbed the contacts on the cartridge.
After I re-installed it, I noticed the light went on/off more reliably....in my case it was just a dirty contact.
Hope this helps someone...I literally only registered to let peeps know.
