Abstract

A character generator for use in a non-mechanical printer is embodied in an electrophotographic printer. A character generator (1) having a plurality of light sources (113) is provided in a non-mechanical printer. The light sources (113) are secured to the character generator (1) in the form of chips (112). Given outage of a light source (113) it is not possible without further ado to replace individual chips (112) and the complete character generator (1) must be replaced. Inventively, the character generator (1) is modularly constructed, i.e. individual modules (11) each having a respective plurality of light sources (113) are detachably secured to a module carrier (13), so that individual modules (11) can be very easily replaced given the outage of individual light sources (113) or of other electronic component parts.
