    Theory of Operation Phaser 7500 Operational Overview The Phaser 7500 is a LED Print Head Color printer that is based on the electrophotographic recording principle. It utilizes a tandem system where each of the colors - Yellow, Magenta, Cyan, and Black (Abbr: Y, M, C, K) has its own Drum and Developer.

    Color Registration Control Overview The Phaser 7500 is a Full Color Printer that uses the tandem system, where each color - Yellow, Magenta, Cyan, and Black has its own Drum and Developer Housing Assembly. Because each color forms an image on their own Drum, which are then overlayed to create one image, color shift may occur due to Drum misalignments, skewed installation positions, and etc.
