Abstract:
The present application is directed to methods for transitioning between color printing and black-only printing in an image forming device. A cartridge is moved between a first position in which color printing may occur and a second position in which black-only printing may occur. In the first position, a color developer unit may be in contact with a color photoconductor unit. The color developer unit may be spaced from the color photoconductor unit in the second position. During the transition, a voltage supplied to the cartridge and a speed of a drive motor driving the cartridge may be adjusted.
