Vertical print engine for electrophotographic apparatus

An electrophotographic printer machine, comprising:

• an electronic controller;
• a first endless loop photosensitive belt stretched across an upper roller and a lower roller such that the exterior surface of the first belt defines a developing position for an electrostatic image in a substantially vertical plane;
• an exposure station on a first side of the printer adjacent the lower roller, configured to focus a beam of light on the developing position of the first belt to form the electrostatic image;
• at least one toner module on a second side of the printer adjacent the first belt to apply toner to the electrostatic image to form a developed image;
• a second endless loop belt stretched between a first roller and a second roller;
• the first roller spaced apart from the second roller and positioned on the first side of the printer horizontally adjacent but vertically lower than the upper roller;
• the second roller positioned on the second side of the printer horizontally off-set and vertically higher than the upper roller, the second loop thereby oriented at an angle with respect to the first loop to have a downward facing outside surface which wraps over the first belt and the upper roller to define an arcuate contact between the first belt and the second belt;
• means for transferring the developed image from the first belt to the second belt;
• and
• a paper handling means for receiving a sheet of paper, communicating the developed image to the paper and fixing the developed image on the paper.
