Abstract: Image forming apparatus includes a logic and control which receives an input indicative of the compliance of a fusing roller and adjusts the temperature of the fuser in response to that input. The apparatus also can receive an input indicative of the melt viscosity of one or more toners making up an image to be fused to similarly adjust the fusing temperature. Alternatively, the pressure in a fusing nip can be adjusted in response to either or both inputs. The inputs can be received in the logic and control from a fusing roller cartridge having machine readable indicating device, indicative of the compliance of the fusing roller. Similarly, the melt viscosity of the toner can be input from a machine readable indicia or the like on a toner bottle.

Abstract: An applicator for a development unit is precisely positioned with respect to an image member, such as a photoconductive drum. The signal strength of the toner monitor is used to accurately locate each developer unit under a stationary photoconductor. The incremental distance from a home position required to position each development unit precisely under a stationary photoconductor is placed in a non-volatile memory so that the information can be used to control the drive motor to repeat the precise positioning at a later time.
