Hi there and welcome
The most common cause will be the cartridges, so we would want to rule this out first.
Can you try different cartridges in the printer and tell me if it then functions correctly please.
Can you please remove the power to the printer (so unplug it from the power socket).
Then wait 10 minutes, connect the power again to the printer, turn it on and tell me please if it is now operating correctly.
Let me know the results please
That is an offer the website has, you can ignore it.
Can you do the last instructions I sent to you though please Jacky?
I repeated these for you below
Have you tried to print from multiple programs to rule out software as the cause for this?
It is the internal print head 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.
