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. L'invention concerne une machine électrophotographique (10) ayant au moins deux modes d'impression, chacun ayant sa propre densité de copie. L'invention concerne un procédé d'étalonnage de la machine électrophotographique (10) qui consiste, notamment, à déposer au moins une languette de toner (62) sur une surface (36) de support d'image. Le dépôt est réalisé dans un premier mode d'impression. La lumière est émise sur au moins une languette de toner (62). On mesure (60) une quantité de lumière (58) réfléchie par lesdites languettes de toner (62). On règle au moins un premier état électrophotographique pour le premier mode d'impression en fonction de l'étape de mesure. On règle au moins un second état électrophotographique pour un second mode d'impression. Le réglage des seconds états électrophotographiques est fonction de l'étape de mesure.
