Description

(54) KNOT OF FIXING THE IMAGE OF THE ELECTROGRAPHIC MACHINE

one

This invention relates to electrographic machines.

The known fixing unit of the image of an electrophotographic machine, which contains a fluorescent lamp, the inputs and outputs of which are connected to the corresponding secondary windings of a network transformer (1.

A disadvantage of the known assembly is low reliability in operation.

The aim of the invention is to increase reliability in operation.

This is achieved by the fact that the node has infrared radiation elements, at the same time, one output of the infrared radiation elements is connected to one of the infrared elements. transformer windings, and their other conclusions are connected to one of the network terminals.

FIG. 1 L 2 is a diagram of the proposed electrographic image fixing unit.

The proposed unit includes an oriping system, a fluorescent lamp, a mirror 3, a lens 4, a bar-cleaning unit 5. A ba, an evacuating unit 6, a selenized cylinders 7 with coronators, a paper line n 8, an infrared emitter 9 and a mains transformer 10.

The image fixing unit of the electrophotographic machine works as follows.

When the node is turned on, the mains transformer 10 warms up the filaments of the luminescence lamps 2. When the lamps 2 are sufficiently heated, they are ignited from the line voltage of a three-phase network. When the lamps light up 2

10, infrared emitters 9 are connected to the mains. After the emitters of the 9th hearth are heated, the remaining units of the machine are: original conductive. system 1, cleaning unit 5, unit 6, paper handling unit 8, which

15, simultaneously with the optical mirrors 3 and the lens 4, the image acquisition process is carried out on the paper. The infrared emitter 9 is used as an image fixing element and

20 ballasts for fluorescent lamps. Connecting the fluorescent lamps 2 through the infrared element 9 of the radiation to the three-phase network allows to ensure the start-up and starting of the fluorescent lamps 2 with rapid heating with a further decrease of the current through the fluorescent lamps 2. In this case, the increase in the resistance of the infrared radiation, and the fluorescent lamps 2 go to the optimum mode of operation. Connecting the transformer 10 according to the circuit shown in FIG. 2, provides a phase shift of the current through the luminaire of the fluorescent lamps 2 relative to the current through the luminescent lamps, which improves the re-charging of the luminescent lamps, increases the power of the irradiated infrared emitter and extends the service life of the luminescent lamps. The invention improves the reliability of the device in operation. L Formula of the image of an electrophotographic machine, containing a fluorescent lamp, the inputs and outputs of which are connected to the corresponding secondary windings of a network transformer, characterized in that, in order to be reliable in operation, it has elements of infrared infrared radiation, while one of the outputs of the infrared elements The radiations are connected to one of the secondary windings of the transformer, and their other conclusions are connected to one of the network terminals.
