In an electrophotographic printing machine, the exposure station includes an imaging module which comprises four side plates, a platen housing and an inner housing, The exposure lamp is rnounted 111 the housing. Hereinbefore, the imaprig rriodule was made from cast aluminum. In the region of the trigger area of the high voltage exposure lamp, creepage and clearance of the alurninum casting resulting in electrical grounding of the exposure lamp. The cxposurc lclrnp must be electrically isolated from the printing machine ground. By changing the material of the imaging module to a plastic material, cost was significantly reduced and the electrical grounding problem solved. Preferably, the plastic material IS a glass filled polyester thcrmosct. The clectrical insulating properties of the thermoset electrically isolates the trigger area of the exposure lamp.
