Input: Purchased product 11/2017 (8 months ago) and only lightly used since then. Started to notice bands of black vertical lines on any scanned or copied documents that went through the document feeder. After trying to clean the machine in accordance with their instructions, they accepted that there is a malfunction and they will be replacing the machine, but only with a refurbished unit. They informed me that you would only get a new unit if the original failed within the first 60 days. That is a lousy warranty in my opinion and I will never purchase another Epson printer/scanner on principle.

Product malfunction but they will only replace with a refurbished machine.
