Apparatus for printing a rigid flat substrate, useful in electronics, biotechnology, nanotechnology or medical technology, comprises a laser printer and a movable holder for positioning the substrate

摘要

Apparatus for printing a rigid flat substrate with a smooth surface comprises a printer (1) with a photoconductor drum for direct transfer of toner to the substrate and a substrate holder (2) that can be moved along a linear axis relative to the printer to position the substrate for contact with the drum. Apparatus for printing a rigid flat substrate with a smooth surface comprises a printer (1) with a photoconductor drum for direct transfer of toner to the substrate and a substrate holder (2) that can be moved along a linear axis relative to the printer to position the substrate for contact with the drum. The printer or the holder is spring-loaded to provide an adjustable contact force between the drum and the substrate and an electrode potential is applied to the holder to generate an electrostatic transfer field between the drum and the substrate.
