Abstract: The present disclosure discloses a moveable feeder assembly/unit for multi-function devices and corresponding retrieval and printing methods. Here, a multi-function device is disclosed. The multi-function device includes multiple trays. Each tray is configured to receive or store one or more media sheets, and further is positioned at a respective vertical height. The multi-function device further includes a single moveable feeder unit for all trays at the multi-function device. The single moveable feeder unit is configured to move across a plurality of positions to reposition itself proximate to a target tray of multiple trays, selected for printing operation.

Abstract: The present disclosure discloses a method and a system for securing a user interface (UI) panel of a multi-function device. The method includes activating a retraction assembly, based on one or more retraction triggering conditions. Once the retraction assembly is activated, multiple components of the retraction assembly start functioning. At first, the UI panel is moved to a first position. Next, the UI panel is moved from the first position to a second position. Then, the UI panel in the second position is retracted into the multi-function device to secure the UI panel inside the multi-function device. This way, the UI panel is secured inside the multi-function device. Later, the retracted UI panel may be moved out of the multi-function device. To move the UI panel outside the multi-function device, the retraction assembly is activated again based on the one or more protraction triggering conditions.

Abstract: A three-dimensional (3D) printer includes a base plate and a nozzle connectable to a source of molten material and operable to eject the molten material onto the base plate that are movable in orthogonal directions to form a 3D object on the base plate. An error detection system detects a dislocation of the 3D object on the base plate during the 3D printing operation, which can lead to stopping the 3D printing process. The error detection system includes a beam emitter and a detector that work in conjunction with a tag formed on the 3D object to determine whether the object has dislocated.

Abstract: A build plate supported on a movable carriage of a 3D printing machine includes a plurality of clamping surfaces that are engageable by a mechanical clamping system that includes a plurality of clamp assemblies mounted on the movable carriage. Each of the clamp assemblies is associated with a corresponding clamping surface and includes a clamping arm configured to rotate and translate to selectively engage the corresponding clamping surface, a follower arm configured to rotate, and a conversion mechanism configured to convert rotation of the follower arm to rotation and translation of the clamping arm. An actuation mechanism includes an actuation face, corresponding to each follower arm. The actuation mechanism is arranged to simultaneously exert a force against the follower arm of each of the clamp assemblies to rotate the follower arm as the carriage moves from a working station to an unloading station of the 3D printing machine.

Abstract: The present disclosure discloses methods and systems for securing a portable storage device connected to a Universal Serial Bus (USB) port of a mufti-function device. The method includes determining if the portable storage device is unattended at the multi-function device for a pre-defined time. Based on the determination, a retraction assembly is activated to secure the portable storage device inside the multi-function device. Once the retraction assembly is activated, the retraction process starts where the portable storage device is retracted to a first position within the multi-function device. Then, the portable storage device is moved from the first position to a second position within the multi-function device. Thereafter, the portable storage device is detached, in the second position, from the USB port to a container of the retraction assembly to secure the portable storage device.
