Abstract: A push-pull latch assembly for a detachable media pick mechanism. The latch assembly comprises a handle that is slidably and axially insertable into a handle base which is mounted to the pick mechanism housing. The handle base includes a pair of cantilevered, opposed latched arms having opposed catches for engagement with a groove positioned adjacent to a free end of a cantilevered drive shaft for the pick mechanism. The handle includes triangular rails having inner and outer ramps used to separate the opposed latch arms. The outer ramp separates the latch arms when the handle is inserted into the handle base. The inner ramp separates the latch arms during removal of the pick mechanism from the drive shaft. An axial pushing force engages the latch assembly to the groove and an axial pulling force disengages the latch assembly from the groove allowing for pick assembly removal.
Abstract translation: 用于可拆卸介质拾取机构的推拉闩锁组件。 闩锁组件包括可滑动地并且可轴向地插入到安装到拾取机构壳体上的把手基座中的手柄。 手柄底座包括一对悬臂的相对的锁定臂，其具有相对的卡爪，用于与邻近用于拾取机构的悬臂驱动轴的自由端定位的槽接合。 手柄包括三角形轨道，其具有用于分离相对的闩锁臂的内部和外部斜面。 当手柄插入手柄底座时，外斜面将闩锁臂分开。 在从拾取机构脱离驱动轴的过程中，内斜面分离闩锁臂。 轴向推动力将闩锁组件接合到凹槽，并且轴向拉力使闩锁组件与凹槽脱离，允许拾取组件移除。

Abstract: A removable media tray assembly for an image forming device according to one embodiment includes a media tray having a bottom surface and a front wall extending upward from the bottom surface. A bottom surface defines a media storage location for storing a stack of media sheets. The assembly includes a housing having an opening therein to receive the media tray. A magnet and a plate provide a latching force FL greater than a pick motor stall force keeping the media tray in a closed position during media picking. A handle assembly including a finger bar and a pivoting link is mounted to the front wall. With the media tray being held closed by the latching force, a user-supplied actuation force FA that is less than 22.2 N applied to the finger bar, pivots the link which acts as a force multiplier providing a release force exceeding the latching force.

Abstract: A push-pull latch assembly for mounting to a cantilevered post. The latch assembly comprises a handle that is slidably and axially insertable into a handle base which is mountable to a member such as a pick mechanism housing. The handle base includes a pair of cantilevered, opposed latched arms having opposed catches for engagement with a groove positioned adjacent to a free end of a cantilevered post. The handle includes triangular rails having inner and outer ramps used to separate the opposed latch arms. The outer ramp separates the latch arms when the handle is inserted into the handle base. The inner ramp separates the latch arms during removal of the latch assembly from the cantilevered post. An axial pushing force engages the latch assembly to the groove and an axial pulling force disengages the latch assembly from the groove allowing for latch assembly removal.

Abstract: A removable media tray with an adjustable rear tray extension operable by a rear media restraint. The tray extension is slidably attached to a front section of the tray via a cam having a locking arm engaged in a J-slot. When in the curved portion of the J-slot the front section and tray extension are locked together. A rear media restraint slidably latching to a track in the bottom of the tray has a locking lobe that engages with a locking notch on the cam. As the media restraint is slid toward the rear, the locking lobe initially rotates the cam moving the locking arm to the straight section of the J-slot, then the locking lobe engages with the locking notch, locking the media restraint to the tray extension. Thereafter, the media restraint and tray extension move together until the end of the J-slot is reached by the locking arm.

The latch assembly comprises a handle that is slidably and axially insertable into a handle base which is mounted to the pick mechanism housing. The handle base includes a pair of cantilevered, opposed latched arms having opposed catches for engagement with a groove positioned inboard a free end of a cantilevered drive shaft for the pick mechanism. The handle includes triangular rails having inner and outer ramps used to separate the opposed latch arms. The outer ramp separates the latch arms when the handle is inserted into the handle base. The inner ramp separates the latch arms during removal of the pick mechanism from the drive shaft. An axial pushing force engages the latch assembly to the groove and an axial pulling force disengages the latch assembly from the groove allowing for pick assembly removal.

Abstract: Separation strips in a dam aid in the separation of adjacent sheets of media being fed from a stack of sheets so that only one sheet is fed to a process station and, more particularly, to separating the uppermost or top sheet of a stack of sheets from the next adjacent sheet during feeding of the top sheet from the stack of sheets of media. When a lift plate is present that adjusts the height of the media stack, rotation of the separation strips to maintain a constant separation angle improves media feed reliability. Curvature of the separation strips may also maintain the separation angle as the lift plate raises the position of the top media sheet.
