Hi there and welcome
Can you perform a cleaning cycle please, to do this hold the stop button for 3 seconds then release and this will start the cleaning cycle.
Let this complete and tell me if it then fixes up the printing quality
Let me know the results please
It is the internal printhead that has faulted and will be leaking
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.
