Abstract: A method and a device for adjusting the printing position of a printer head. When a recordable medium having a greater thickness than that of a standard cut sheet of letter size paper is inserted in an electrophotographic apparatus, it is often necessary to increase the distance between the top recordable medium in the paper supply tray and the paper input port in the electrophotographic apparatus to allow a greater number of thick sheets of recordable medium to be loaded. One method of increasing the distance is to rotate a guide panel into a position that abuts the electrophotographic apparatus and increases the distance between the paper supply tray and the paper receiving port. Unfortunately, this causes the printer head to require adjustment, as the horizontal positioning of the printable medium fed into the printer has changed. This inventive method and device uses a sensor to determine when the guide panel has been rotated and automatically adjusts the printer head's position.

The driving shaft may be rotatably supported adjacent the first, second and third worms.

Abstract: A flexible plate is removed from the surface of a cylinder in a rotary printing press by supplying a fluid under pressure to a chamber into which the plate ends have been inserted. The fluid under pressure creates a positive pressure in the chamber which is sufficient to push at least one of the plate ends out of the chamber.

Abstract: A printer which prints information on articles such as filter cartridge assemblies, minimizes ink splattering and increases speed by shielding the lower portion of ink pickup rollers with an ink shielding plate. By utilizing the ink shielding plate, the speed at which the printer operates is doubled and cleanup of splattered ink is minimized.

Abstract: A roller cleaning system includes a pad disposable against a roller for cleaning the surface of the roller when the roller is rotated. The pad is supported in a frame which may be stationary or mounted for translation so that the pad may traverse a length of the roller while cleaning the roller surface. The pad may be further provided with an actuator for urging a portion of the pad against the roller at an additional force. The frame has a first portion disposed at a fixed distance from the surface of the roller and a second portion carrying the cleaning pad, the second portion being pivotable from the first portion about an axis parallel to the axis of the roller. Means are included for measuring torque exerted on the pivot, which torque is indicative of frictional drag on the cleaning pad. In a preferred embodiment, a piezo-electric strain gauge disposed between the frame portions is connected in a feedback loop with a controller and the pad actuator.

Abstract: To remarkably decrease the amount of material for the manufacture of ink containers and the volume of the ink containers after use, so as to contribute to the economy of natural resource consumption and solving the problem of destruction of global environment by the waste of products, without sacrificing the easiness of handling the ink containers for printers, the ink container for directly storing ink is principally constructed by a thin walled vessel contractible according to discharge of the ink therefrom, with a nozzle being connected to an end portion of the vessel, with a disk handle being mounted to the nozzle, so that the disk handle can be grasped by five fingers of a hand for carrying the ink container by hand and for removing a cap therefrom. For the ink container being mounted into a printer, the ink container is mounted into a reinforcing case with the nozzle and the disk handle, so that the ink container is handled like the case.

Abstract: A fixing unit includes a heat roller accommodating a heater and a press roller movable toward and away from the heat roller. Both shaft members of the heat roller are supported by two receiving members, with a clearance provided between each shaft member and respective receiving member. A driven gear is provided to one of the shaft member, which engages a rotating mechanism for rotating the heat roller. The fixing unit further includes a biasing member which biases the other shaft of the heat roller away from the press roller within the clearance, in such a manner that the heat roller and the press roller become parallel when the above-described one shaft member is urged away from the press roller due to the meshing engagement of the driven gear and the rotating mechanism.

Abstract: A platen holder 8 is provided with a stopper member 12 which comes into contact with a lever 20 depressed when the platen holder 8 is rotated to a home position by removing of a cassette cover 2B from an upper cover 2A.

Abstract: A ferromagnetic foil carrying a layer of a pressure sensitive adhesive for adhesive attachment to a printing plate to be used in a letterpress or flexographic printing operation. The ferromagnetic foil preferably is formed of a cold rolled steel having a thickness in the range of from about 0.001 inch to about 0.007 inch. The metal foil allows the printing plate to be adhered to the outer surface of a magnetized printing cylinder due to the magnetic attraction between the printing cylinder and the ferromagnetic foil. If the printing cylinder is not magnetized, but is formed of a ferromagnetic material, a flexible magnetic pad is applied to the outer surface of the cylinder, and the ferromagnetic foil-backed printing plate is then placed on the flexible magnetic pad.
