Patent ID: 7027078

Claim:
A control device to optimize load image generation in an electrophotographic process, comprising: a light-sensitive and temperature-sensitive photoconductor layer for pixel-by-pixel exposure with a temperature-sensitive light source; the photoconductor layer being more sensitive with rising temperature, such that given a predetermined quantity of light and predetermined charge it discharges deeper; the light source emitting a lesser luminous power with rising temperature given a same actuation power; a respective temperature compensation for the light source and for the photoconductor layer; the temperature compensation for the photoconductor layer being at least one of adapting current flowing through the light source and adapting exposure time of the light source; the temperature compensation for the light source being at least one of correction of the current flowing through the light source and a change of the exposure time; for the temperature compensation of the photoconductor layer a measurement event which measures a discharge depth of the photoconductor layer given predetermined luminous duration and predetermined current throuah the light source; a temperature of the light source measured in the course of the measurement event being used as a reference value for the temperature compensation of the light source; and light energy of the light source being held constant between successive discharge depth measurements.
