Hi there and welcome
I am not sure if you did the clean in the ccorrect manner, so please review my instructions below and ensure this is exactly what you did please
Like displayed here
Then close up the printer and tell me if the error clears please
Ok, have you opened it and checked for any paper? Even a small piece can cause a jam which brings this error.
If you have a vacuum cleaner, use this and try to dislodge anything stuck in there.
Let me know please
ok, Can you please remove the power to the printer (so unplug it from the power socket).
Let me know the results please
It is the internal printhead that has faulted, this now confirms it
I am really sorry about this and you are going to have to return the printer to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.
