Abstract: Methods and devices for aligning a media sheet in a media feed path of an image forming device. One embodiment includes a drive shaft with skew correction rollers spaced apart on the drive shaft. The media sheet contacts a first skew correction roller and then contacts a second skew correction roller. The drive shaft is then rotated, driving the second skew correction roller and aligning the media sheet to the media feed path.

Abstract: Scanning devices and method of use that permit the capture of high resolution images of an original that is illuminated by a light source that is located outside of the optical field of view of an image detector. In one aspect, the image detector may be a monochrome sensor that sequentially captures different color plane images of an original that is illuminated by different colors. The different color plane images may be processed to generate a full color copy of the original. Light and images may be directed through tapered optical waveguides to minimize the volume of the scanning device. The image detector may include a first associated waveguide while the light source may include a second associated waveguide.

Abstract: The present application is directed to devices and methods for moving media sheets in an image forming device. In one embodiment, a contact member includes a contact roller that contacts a top-most media sheet in a stack of media sheets positioned on a support surface in an input area of the image forming device. A hub extends outward from an axial side of the contact roller. The hub includes a smaller length than the contact roller, forming a gap between the hub and the top-most media sheet when the contact roller is in contact with the top-most media sheet. The hub prevents or reduces transverse buckling of the top-most media sheet when it is moved from the stack of media sheets.

Abstract: Multi-functional image forming devices that may include a base color laser printer comprising a front side, a back side, a top, and a bottom. The color laser printer may further include a media path, a laser printhead, and a plurality of image forming units. A scanning mechanism comprising a scan bed may be mounted on the top of the base color laser printer. In one embodiment, the media path includes a first section positioned within the base color laser printer and a second section that extends between the scanning mechanism and the top of the base color laser printer. In one embodiment, the scanning mechanism is pivotally mounted to the base color laser printer and movable to access the second section of the media path.

Abstract: The present application is directed to toner cartridges with a bearing plate to locate and provide a bearing surface to one or more rotational members. The bearing plate may be positioned on an outer wall of a body of a toner cartridge. The bearing plate may include apertures to receive shafts of a series of rotational members. The bearing plate may locate the shafts relative to the body such that each is operatively connected together through a gear train. Bearing plate may also provide a bearing surface for the rotating shafts.
