The scanner option assembly comprises a housing removably attachable to a bottom of the image forming device, and a scanner assembly mounted in the housing and being positionable to receive an original for scanning. When the housing is attached to the bottom of the image forming device, the scanner assembly receives power from the image forming device with the scanner assembly being in operable communication with a controller of the image forming device for receiving instructions from and providing scan data of an image of the original to the controller. The scanner assembly includes at least one of a flatbed scanner slidably extendible and retractable through an opening of the housing, and an automatic document feeder (ADF) assembly for automatically feeding one or more media sheets into an image capture area of the scanner assembly.
