I have been a happy user of the Phaser 6180MFP for several years. It is a very robust machine now running with a MacBook Pro running OS X Yosemite. I happened to look at the User Guide and it showed a complex scanning control panel for both PC and Mac that seemed to allow advanced adjustment of the scanned image. All I have is the Express Scan Manager, which permits only very basic adjustments. Is a better control panel available?
