Abstract
A system for increasing the life of flexible photoreceptor belt in a copier/printer includes tensioning and de-tensioning the photoreceptor belt. The photoreceptor belt is de-tensioned at the end of daily use, on weekends, and on non working days in order to reduce belt dimensional elongation due to creep which thereby suppresses the development of charge transport layer cracking in the photoreceptor belt and increases belt service life of the photoreceptor by a factor of about 2.times..
