Abstract
The corotron wire of a corotron device is introduced with a retainer element, such as in a printer or copier. At least one corotron wire is held by the retainer element and the carrier material for a latent image residing there opposite is conducted past the corotron wire. The carrier material and the corotron wire lie in planes arranged substantially parallel to one another. The retainer element lies on bearings at at least two bearing points, the bearings being rigidly connected to the guide element and pressed onto the bearings with a spring power. A method is also provided for introducing the corotron wire of a corotron device with assistance of the retainer element.
Claims39
A corotron for electrographic processes in a printer or copier, comprising:
- at least one corotron wire held by a corotron wire insert and past which a carrier material for a latent image residing there opposite is conducted;
- a guide element with which the carrier material is guided;
- the carrier material and corotron wire lying in planes arranged substantially parallel to one another;
- the corotron wire insert lying on bearings at at least two bearing points, said bearings being rigidly connected to the guide element and being pressed onto the bearings with a spring power;
- and
- the corotron wire insert is guided in guide elements, the guide elements and the corotron wire insert having play in a direction of the carrier material, and the corotron wire insert lying on the bearings at said bearing points that are arranged at both sides of the carrier material.
An arrangement for a corotron for electrographic processes in a printer or copier, comprising:
- a carrier in which a corotron wire supplied with an electrical high-voltage is arranged;
- at least one voltage supply unit that generates the high voltage;
- the carrier accepting the voltage supply unit;
- the corotron wire in the carrier being arranged in a corotron wire insert;
- and
- an electrical connection between the voltage supply unit and the corotron wire insert containing at least one plug-type connector that is movably arranged so that the corotron wire insert is movable in the carrier in a connected condition of the plug-type connector.
A corotron insert into which a corotron wire is introduced with the assistance of a retainer element, comprising:
- the retainer element being detached from the corotron wire after insertion of the corotron wire, said retainer element being removed from the corotron insert;
- at least one end of the corotron wire is arrested in the corotron insert after insertion of the corotron wire;
- the retainer is reconnectible with the corotron wire;
- arrest of the corotron wire in the corotron insert is releasable;
- and
- the corotron insert wire with the retainer element is removable from the corotron.
A retainer element for insertion and removal of a corotron wire in a corotron device, comprising:
- an opening for acceptance of a corotron wire provided with end pieces;
- the opening being formed by two arcuate legs that partially embrace the end pieces and the corotron wire being arranged between the end pieces upon insertion;
- the arcuate legs forming spring elements that fix the end pieces with the corotron wire in the retainer element;
- and
- guide elements operating with the corotron device for longitudinal insertion of the end pieces and corotron wire into the corotron device.
A corotron for electrographic processes in a printer or copier, comprising:
- at least one corotron wire held by a corotron wire insert and past which a carrier material for a latent image residing there opposite is conducted;
- a guide element with which the carrier material is guided;
- the carrier material and corotron wire lying in planes arranged substantially parallel to one another;
- the corotron wire insert lying on bearings, said bearings being connected to the guide element and being pressed onto the bearings;
- and the corotron wire insert is guided in guide elements, the guide elements and the corotron wire insert having play in a direction of the carrier material, and the corotron wire insert lying on the bearings at said bearing points that are arranged at both sides of the carrier material.
A method for introduction and removal of a corotron wire into and from a corotron device, comprising the steps of:
- holding the corotron wire with assistance of a retainer element during introduction into the corotron device;
- upon introduction of the corotron wire in the corotron device, arresting at least one end of the corotron wire;
- removing the retainer element from the corotron wire after the arrest;
- and
- for removal of the corotron wire, connecting the corotron wire in the corotron device to the retainer element;
- undoing an arrest of an end of the corotron wire in the corotron device;
- and
- removing the corotron wire together with the retainer element from the corotron device.
A method for removal of a corotron wire from a corotron device, comprising the steps of:
- connecting corotron wire in corotron device to retainer element;
- un-doing an arrest of an end of the corotron wire in the corotron device;
- and
- removing the corotron wire together with the retainer element from the corotron device.
