Abstract

An electrophotographic machine (10) has at least two printing modes, with each printing mode having a respective printing density. A method of calibrating the electrophotographic machine (10) includes depositing at least one toner patch (62) on an image-bearing surface (36). The depositing is performed in a first of the printing modes. Light is emitted onto the at least one toner patch (62). An amount of light (58) that is reflected off of the at least one toner patch (62) is measured (60). At least one first electrophotographic condition for the first printing mode is adjusted dependent upon the measuring step. At least one second electrophotographic condition is adjusted for a second of the printing modes. The adjusting of the at least one second electrophotographic condition is dependent upon the measuring step.
