摘要:
An electrographic printing unit containing at least two printing units whose transfer printing points lie opposite one another is shown and described. This configuration enables high-speed duplex printing. Also disclosed is a printing unit with a photoconducting band and two exposure units located along the perimeter thereof. The exposure units superimpose two latent images each time the photoconducting band rotates.

A testing apparatus for a radiation sensing integrated circuit comprises a load board (101), a test socket (102), suitable for the device under test DUT (103), and a plunger (104). A radiation source (107) is provided on the load board (101) adjacent to the test socket (102). The radiation source (107) generates radiation for testing the response to stimulus of the radiation sensing element of the DUT (103). To enable the sensing element of the DUT (103) to be exposed to the radiation, a pathway (108) is provided through plunger (104). The pathway (108) has a U-Shape with the end of one side of the U being adjacent to the radiation source (107) and the other end of the U being adjacent to the sensing element of DUT (103). Prisms (105, 106) are mounted at the base of each side of the U so as to reflect incident light along the pathway (108), such that radiation entering the pathway (108) from the radiation source (107), travels along the U and exits the other end of the U where it is then incident upon the radiation sensing element of DUT (103).
摘要:
A printer or copier and method generates toner images for transfer onto a recording medium. A latent charge image is generated on a photoconductor and is developed by the application of toner by at least one developer station to generate the toner image for transfer to the recording medium. A plurality of the developer stations are provided along the photoconductor to develop the images in color using a color separation method. A transfer band collects the color separations on top of one another to generate the overall toner image which is transferred to the recording medium. Multiple modules, each with developer stations, a photoconductor and a transfer band may be provided for one sided or two sided printing.
摘要:
A printing or copying machine has a photoconductor (10) with associated recording and developing station (EY, EM, EC, EB) for producing single-color or multi-color toner images on the intermediate image-carrier (10). The toner images are transferred electrostatically, in a transfer zone (T) onto a belt-type transfer element (16) and then, in transfer and fusing zones (U1, U2), printed from the underneath from the transfer element onto the recording carriers (24). In order to facilitate the fusing of the transfer image in the transfer and fusing stations (U1, U2), heating units (23, 31) for heating the toner images on the transfer element (16) and/or for heating the recording carrier (24) are provided. Between the first and the second transfer and fusing station (U1, U2), a turning station (W) is arranged. The printing or copying machine can be operated in the simplex and duplex printing mode of operation to produce single-color or multi-color copies.
