摘要:
A color electrophotographic printing machine has a drive system which includes a first, second and third motor-and-gear-train configurations mounted on a frame and coupled to first, second and third combinations of multiple color developer drive assemblies, multiple color photoconductive drum drive assemblies, a black developer drive assembly and a black photoconductive drum drive assembly. The first and second configurations are operable at first and second motor gear mesh frequencies and the third configuration is operable at a motor gear mesh frequency that can be substantially the same as one of the first and second motor gear mesh frequencies. The first combination includes yellow, cyan and magenta color developer drive assemblies, the second includes yellow and cyan color photoconductive drum drive assemblies, and the third includes a magenta color photoconductive drum drive assembly with the black developer drive assemblies and black photoconductive drum drive assemblies.

An Oldham coupler assembly capable of transferring rotary power between two shafts in a developer unit of an image forming apparatus that includes an input plate and an output plate made of metal and a star plate made in plastic mechanically coupled and positioned in between the input plate and the output plate. A spline component made of metal is rigidly and integrally attached to the input plate, the spline component including a tubular spline portion that includes a plurality of wear strips made of plastic, the output plate having a plastic material coated along a portion of an outside diameter of the output plate. The input and output plates further include a plurality of openings to receive a plurality of wheels and pins. This structure allows a sufficiently stiff drive system to substantially eliminate fine line jitter by raising the natural frequency of the drive system.

The present application is directed to systems and methods to control access to an interior of an image forming device. The image forming device may include a body with a door that is movable between open and closed positions. In the open position, access is gained to an interior of the body. A controller controls a latch through a motor arrangement to lock and unlock the door. A user interface may be positioned on an exterior of the body to allow a user to enter commands to lock and unlock the door. Additional elements may also be included within the interior of the image forming device and operated with the motor arrangement.

A color electrophotographic printing machine has a drive system which includes a frame and first, second and third motor-and-gear-train configurations mounted thereon at a common location and respectively drivingly coupled to first, second and third combinations of multiple color developer drive assemblies, multiple color photoconductive drum drive assemblies, a black developer drive assembly and a black photoconductive drum drive assembly so as to operate the same. The first and second configurations are operable at first and second motor gear mesh frequencies that are different and the third configuration is operable at a motor gear mesh frequency that can be substantially the same as one of the first and second motor gear mesh frequencies. Also, the first combination includes yellow, cyan and magenta color developer drive assemblies, the second combination includes yellow and cyan color photoconductive drum drive assemblies, and the third combination includes a magenta color photoconductive drum drive assembly with the black developer drive assemblies and black photoconductive drum drive assemblies

The application includes various embodiments of devices and methods for mounting a motor within an image forming apparatus. The motor is mounted on a frame and positioned to engage and drive a component within the image forming apparatus. In one embodiment, the component is an imaging unit. The frame includes an opening to receive the motor. A locating member is attached to the frame and extends into the opening to contact the motor and provide accurate positioning for engagement with the component. The locating ring provides for a press fit with lower forces. Additional fasteners may fixedly connect the motor to the frame and maintain the accurate positioning provided by the locating member.
