摘要： A biasing mechanism in an image forming apparatus exerts a variable force on a removable cartridge unit to generate a nip force between a roller in the cartridge unit and another roller. A pivot member is fixed to the apparatus housing. An arm is pivotally mounted in the housing about the pivot member, with the arm in contact with a protrusion on the cartridge unit. A force generating member is mounted in the housing and contacts the arm so as to urge the arm to pivot about the pivot member and press against the cartridge unit. The resulting force exerted on the cartridge unit by the arm varies according to the point of contact between the cartridge unit and the arm. In some embodiments, the arm and the cartridge unit protrusion are electrically conductive, and an electrical contact is established as the arm is pressed against the protrusion.

摘要： An image forming apparatus includes a toner bottle, a supply unit that supplies toner from the toner bottle to a downstream side, a door that is openably provided to execute toner replenishment, an opening/closing sensor that senses opening/closing of the door, and a unit that renders the supply unit inoperable if the door is open. If the opening/closing sensor detects the opening of the door, counting of the number of prints is started. Then, the control unit detects whether the door is closed. If the door is still opening, the control unit checks whether the number of prints has reached a predetermined value. If not, the control unit sets the image forming apparatus in a printing state. If yes, the control unit stops the printing operation. If the closing of the door is detected, the control unit resets the count value. Subsequently, the control unit determines whether the initial value of the number of prints, which is set through a control panel at the time of starting the printing operation, is reached. If the initial value is reached, the printing operation is completed.

摘要： A developer cartridge is detachably mountable in an image-forming device having a driving rotator. The developer cartridge includes a developing roller and a driven rotator. The driven rotator is movable in an advancing direction parallel to an axial direction of the developing roller toward the driving rotator and in a retracting direction opposite the advancing direction. The driven rotator receives a driving force from the driving rotator when coupled with the driving rotator, thereby rotating the developing roller.

摘要： A type 2 IP-5000 toner cartridge is converted to a type 1 HP-5000 toner cartridge. The device and method are utilized by placing a repair contact over-plate over a double-spring contact subassembly to make a flat surface for the coil-spring contactor to engage while it rotates so that there will be electrical communication between the double-spring contact subassembly, the repair contact over-plate, the coil-spring contactor, the flange and the developer roller. The repair contact over-plate has at least two attachment-alignment holes used to lock into posts of the gear housing. Various forms of locking, removable locking or non-locking may be implemented into the repair contact over-plate. Installation of the repair contact over-plate may be facilitated by using a tool. The tool may consist of one plate, bar or flat srewdriver with at least one attachment-alignment hole to press the repair contact over-plate over the posts.

摘要： When a new developer cartridge is initially mounted in an image-forming device, a toothed part of a sensor gear disposed in the cartridge is brought into meshing engagement with an agitator drive gear disposed in the image-forming device. The sensor gear is driven while its toothed part is in meshing engagement with the agitator drive gear and driving of the sensor gear is stopped when its toothless part opposes the agitator drive gear. One or more contact protrusions are formed on the sensor gear to be movable therewith. An information-detecting mechanism detects how many contact protrusions are formed on the sensor gear during driving of the sensor gear. Based on the detection results, whether the mounted developer cartridge is a new product or not is determined, and information on the maximum sheets to be printed with the mounted developer cartridge is acquired.
