After some research, I came across the Epson ET2721 Adjustment Program, which supposedly can help fix this issue. However, I am not sure where to download this program and how to use it. Has anyone here had experience using the Epson ET2721 Adjustment Program? Could you please provide some guidance on where to find it and how to use it properly? Any help would be greatly appreciated. Thank you.</blockquote>
