摘要:
A printhead capping assembly includes a cap holder and a printhead cap. The cap holder defines a cavity and a vent exit. The printhead cap has a base and a lip portion extending from the base. The lip portion defines an open interior region. The base is inserted into the cavity of the cap holder. The base includes a serpentine channel extending from the open interior region to the vent exit of the cap holder.

A printhead capping assembly includes a cap holder, a printhead cap and a pin. The pin includes a head and a shaft. The shaft has a proximal end and a distal end, with the proximal end being adjacent to the head. The head has an outer periphery, and a bottom surface extending outwardly from the shaft toward the outer periphery. The pin has a channel including a first channel portion and a second channel portion. The first channel portion extends from the outer periphery of the head to the shaft. The first channel portion is connected to the second channel portion. The pin is inserted through the second hole and into the first hole to place the head in contact with the second base of the printhead cap. The second base of the printhead cap seals along the first channel portion to define a first vent path portion.

A backup roller is formed by a member having a rotational axis and a circumferential region around which a plurality of teeth are arranged. Each tooth of the plurality of teeth has a tip end extending in a direction away from the rotational axis. When the backup roller is rotated the tip end of each of the plurality of teeth sequentially extends toward the rotational axis of a drive roller at an angle non-orthogonal to the rotational axis of the drive roller.

The present application is directed to a pick tire for moving media sheets within an image forming device. The pick tire includes a base with an inner surface that faces towards a central opening and an outer surface that faces away. A plurality of teeth are formed on the outer surface and contact the media sheets. The plurality of teeth are integrally molded with the base. The molded construction provides for more economical manufacturing costs, better manufacturing consistency, and increased durability.

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.

An imaging apparatus includes a printhead carrier configured for movement along an X-axis. The printhead carrier includes a carrier housing having a first bearing pocket and a second bearing pocket. The first bearing pocket and the second bearing pocket are spaced apart along the X-axis. A Z-axis passes through a central region of the carrier housing. The Z-axis is substantially perpendicular to the X-axis. A first bearing is configured to be received in the first bearing pocket. The first bearing includes a first curved outer surface having a curve that extends in a direction of the X-axis. The curved outer surface is received in the first bearing pocket to facilitate a rotation of the first bearing in relation to the Z-axis of the carrier housing. A second bearing is configured to be received in the second bearing pocket.
