At first I thought I was going to have to spend a lot of money and have to spend a lot of time fixing my issue. It was actually the complete opposite, it was very cheap/affordable and super easy to do. They give you all the steps and explain everything very clearly. do not waste your time with dealing with Epson. This was definitely the best decision to make. Will be back when I need to reset my printer again! Thank you 2manuals.com!!!!! To bad there isnt an AMAZING rating!!
