Übersetzung für "Image drum" in Deutsch

In addition, when pale liquid or solid toners are used, the toner-containing latent image on the drum can be checked visually if this is necessary.

A charge image on photoconductor drum 1, which has, for example, a selenium coating, is treated, in the region of a development electrode 2, with a developer liquid 3.

The electrophotographic system 4 a includes as its central constituent an image drum 5, that is, an OPC photoconductor drum, which is provided with a photoconductive layer, which is exposed to light via a suitable, preferably digitally designed photo-exposure assembly 6, such as a controlled laser beam, or more simply an LED writing head, for instance with a resolution of 400 dpi for a writing width of 36?, depending on the decoration or caption to be applied.

The electrophotographic system 4 a further includes a developer unit 8 a with a preferably ceramic and in particular two-component toner system, of the kind disclosed for instance in the above-cited German Patent DE 44 13 168 C2, by means of which the latent electrostatic charge image on the image drum 5 is developed into a visible toner image.

The toner image created on the image drum 5 in accordance with the image to be applied is then transferred to the product 2 by the transfer system 4 .

The transfer of the toner image from the image drum 5 to the glassy product 2 by means of the electrostatic field created by the coronas 9, 10 is done as follows:

Meanwhile, the toner image on drum 14 is transferred to an image-receiver sheet (not shown), and the drum surface 18 is cleaned at a cleaning station 28 .

In use, the image-recording drum 12 is supported at its opposite ends 12 A and 12 B by a pair of gudgeons 40 and 42 that are releasably press fit into the respective ends of the drum.

The toner image, comprising negatively charged toner particles, that is located on the image drum 5 is taken over in the contact zone from the transfer roller 7, which at this point is positively charged by means of the transfer corona 9 a 1 .

This simplifies the preparation of the transfer roller 7 for the transfer of the next charge image from the image drum 5, and there is no risk that ghost images, which Would be dragged along to the next image will be created.

The image drum has been known and the invention does not change the characteristics, operation or life of the drum.

However, in this case the transfer device is not designed to transfer a toner material that has been developed specifically to be deposited in a uniform layer thickness on an image drum that has been either charged or magnetized as required.

The system employs a photoconductor drum 1 with toning station 5 that places a toner based image on photoconductor drum 1 and an electrostatic cleaning station 3 that removes residual toner from the photoconductor drum 1 .

The replacement of the image drum and the flange is not a re- production, because in these parts, the invention is not reflected.

On the lower storey, there was much free space into which the pattern generator, the marble track and the image drum were then integrated – each of which enables kids to explore the principles of cause and effect.Â

For example, a 600 dpi (dot per inch) A4-size print head has 4,992 dot LEDs arranged in a straight line that each emit light and turn off, depending on the print data, to write the latent image on the image drum.

OKI's LED print heads are made up of a chip-on-board (COB) that mounts multiple epifilm LED arrays on a circuit board for the print width, whether A4, A3, etc., and a rod lens array that produces images on the image drum from the light emitted by the LEDs.

The charged dots pick up the electrically charged ink particles, transferring the image to the drum, which is then transferred to the paper using heat and pressure, all of this inside the printer.

In this apparatus, liquid toner is applied to a latent image carrier in the form of an imaging drum.

The imaging drum 1 rotates in the direction of the arrow 1 ?.

The second plate 5 b is also slidable toward the imaging drum 1 .

As a result, excess liquid still adhering to the imaging drum 1 is atomized and carried away.

In this way, toner which does not adhere to the imaging drum is sucked off the imaging drum.

Toner which adheres to the imaging drum cannot be taken up by the excess passage.

For example, four raster lines with a low resolution, for example, two points/mm, are disposed parallel to one another whereby the image of the raster line parallel arrangement arising in such a manner is reduced by way of a lens so that a single line can be imaged onto the drum 127 with increased resolution.

Switches according to the above-described principles can be employed in a line-shaped disposition for fiber optical displays or for "writing" the charge images on semiconductor drums in a laser printer.

For a printing process, in particular with an electrographically operating printing machine, where an imaging drum is newly illustrated or each printing process, meaning that the printing takes place without a permanent printing form (so-called non impact printing), a path in the transfer direction (intrack) of a print substrate must be determined for the various requirements.

To this end, each of the printing devices comprises an electrophotographic imaging drum 10, a printhead 11 for the imaging of an imaging drum 10, a toner station 12 for applying toner on the imaged imaging drum 10 for the development of the image in question and a rubber blanket drum 13 to transfer the image developed onto the print substrate.
