I purchased the above printer and it ran on the original cartridges for 6 months until they ran out.
I decided to try and save money, and help the environmet, by having the cartridges refilled, however the refilled cartridges do not work as the printer detects them staright away and comes back with a U051 error - ink cartridge can not ber recognised. (error displayed on LCD screen of printer and on the PC Monitor if you attempt to print anything)
As soon as put in genuine cartridges in the printer fires up agian fine.
Does anyone know how I can bypass this to enable me to use refilled cartridges again?
No, I still haven't solved this. I have tried refilling genuine catridges but it always throws up the error. It looks like it recognisies that it is the same catridge and thinks it is empty and i can not seem to override it.
