Transfer printing station for an electrographic printer or copier

An electrographic printer or copier device, comprising:

• at least first and second electrographic print engines which can record an image on a recording medium, the second print engine following the first print engine;
• at least the second print engine comprising a transfer printing station having a transfer roller to which has been applied a transfer voltage to transfer a toner image generated on an electrographic intermediate carrier onto the recording medium in a transfer printing area of the transfer printing station;
• and
• the transfer roller in the transfer printing area elastically pressing the recording medium onto the intermediate carrier such that substantially no print image errors occur, even given a rippled recording medium.

A method for transfer printing from a toner image applied on an electrophotographic intermediate carrier to a recording medium, comprising the steps of:

• providing a transfer printing station having a transfer roller;
• arranging the transfer roller in a carrier unit lying adjacent to the intermediate carrier so that it can be pivoted from the intermediate carrier;
• elastically mounting the transfer roller in a channel of the carrier unit in a direction of the intermediate carrier and permitting it to rotate;
• and
• generating the toner image on the electrophotographic intermediate carrier, applying a transfer voltage to the transfer roller, and transferring the toner image generated on the electrophotographic intermediate carrier onto the recording medium in a transfer printing area of the transfer printing station, the transfer roller pressing the recording medium over its entire width onto the intermediate carrier such that substantially no print image errors occur, even given a rippled recording medium.

A print device, comprising:

• at least first and second print engines that sequentially print on a same recording medium;
• at least the first print engine printing on the recording medium comprising a thermofusing station;
• and
• at least the second print engine subsequent to the first print engine comprising in a transfer printing area a pressing roller that elastically presses the recording medium onto an intermediate carrier such that substantially no print image errors occur even when the recording medium is stressed by thermofusing of the preceding first print engine.

• the transfer roller in the transfer printing area pressing the recording medium onto the intermediate carrier such that substantially no print image errors occur, even given a rippled recording medium;
• the transfer roller being arranged in a carrier unit lying adjacent to the intermediate carrier;
• and
• the transfer roller being mounted in a channel of the carrier unit.
