I'm on the edge with replacing my Epson Workforce large format printer scanner with the Brother MFC-L8905 (due to cost of ink replacement) and am seeing some comments in reviews concerning grainy color scans. I do quite a bit of photo scans for digitizing and am wondering if anyone here has experienced that. Might be a deal breaker for me if it's an issue. Any other comments on this model would be appreciated. Thanks so much.
