Error on scanning: scanning Flow Component has encountered a problem

Hello,
My scanner on the F2280, has been working fine until last week, when it stopped working and a message came up 'HP CUE – scanning Flow Component has encountered a problem and needs to close.'
I have tried scanning, by pressing the scan button on the printer itself and also by going into the HP solution center. Both resulted in the error message. The copier function and printer work fine. I have not loaded any new software or done anything that might have caused the problem – any ideas?
Thank you.
