G03G15/235 - CPC Classification

Classification description:

Apparatus for electrographic processes using a charge pattern involving the combination of more than one step according to groups  -  specially adapted for copying both sides of an original or for copying on both sides of a recording or image-receiving material; Arrangements for copying on both sides of a recording or image-receiving material using a single reusable electrographic recording member by inverting and refeeding the image receiving material with an image on one face to the recording member to transfer a second image on its second face, e.g. by using a duplex tray; Details of duplex trays or inverters the image receiving member being preconditioned before transferring the second image, e.g. decurled, or the second image being formed with different operating parameters, e.g. a different fixing temperature
