Your printer is just fine, don't replace it. What you do need to replace is your scanner software. All-in-one printers are actually two completely separate devices and use different software, they are not bound to each other. I discovered Vuescan about 3 years ago and use it exclusively for my scanner. It is an app that totally replaces your printers scanner app seamlessly. About $30-$40 one time cost. You can scan any mix of document sizes and best of all the output file does not close when your hopper goes empty. You can keep on feeding more documents and it will add to the end of the file, even a day or year later. Very robust and does much more. It's a must have. If you must scan, and most of us do, this will make your life a lot easier. PS I have no affiliation with Vuescan.
