摘要： An imaging device having a fuser and print engine architecture that enables complete interchangeability between fuser types with a common print engine. The imaging device has a frame configured to separately receive a first fuser assembly of a first fuser type and a second fuser assembly of a second fuser type different from the first fuser type. The first fuser assembly includes a first fuser frame having a first datum tab. The second fuser assembly includes a second fuser frame having a second datum tab. The frame of the imaging device has a datum aperture that is sized to receive the first datum tab that when inserted into the datum aperture, causes the first fuser assembly to be positioned at a first operative position, and the second datum tab that when inserted into the datum aperture, causes the second fuser assembly to be positioned at a second operative position.

摘要： An imaging device, including a locking assembly connected to the frame of the imaging device and selectively engaged with the fuser assembly thereof when the fuser assembly is mounted to the frame. The locking assembly includes a lock member slidingly coupled to the frame between a first position in which the lock member engages with the fuser assembly for locking the fuser assembly to the frame and a second position in which the lock member is disengaged from the fuser assembly to allow the fuser assembly to be disconnected and removed from the frame. A lever mechanism is movably coupled to the frame and coupled to the lock member, wherein actuation of the lever mechanism moves the lock member between the first position and the second position.

摘要： An object of the present invention is to increase the accuracy of positions of a drive gear and a driven gear without an increase in size of an apparatus. In an image forming apparatus, a driven gear 108 is provided on a free end side of a roller shaft 106 rather than at a portion 106a, of the roller shaft 106, supported by a fixation unit 50. A main assembly of the apparatus 1 has a support member 103 that is movable between a support position where, with the fixation unit 50 attached to the main assembly of the apparatus 1, a free end-side end of the roller shaft 106 is supported and a non-support position where, with the fixation unit 50 removed from the main assembly of the apparatus 1, the free end-side end of the roller shaft 106 is not supported.

摘要： A fixing device includes a housing detachably attached to a body of an image forming apparatus, a fixing unit mounted on the housing to heat and fix an unfixed toner image onto a recording medium, a locking mechanism to lock and unlock the housing in the body of the image forming apparatus by switching its own position from a locking position to an unlocking position, vice-versa, and an operating member integrally connected to the locking mechanism to operate the locking mechanism. First and second handling members are provided on lower and upper sides of the housing, respectively, to be handled when the housing is either attached to or detached from the body of the image forming apparatus. The operating member approaches the second handling member when the locking mechanism changes its position to detach the housing from the body of the image forming apparatus.
