Switchable dual wavelength flood lamp for simplified color printing architecture based on xerocolography

摘要

Full color, two-pass imaging process using black, magenta, cyan and yellow toners and Non-Interactive Development (NID) without fringe field development. A switchable wavelength flood lamp structure is provided for producing blue and red light. One wavelength is used during the first pass of a photoreceptor through various processing stations for revealing an imagewise voltage for development with magenta toner using an NID system. The other wavelength is used during a second pass of the photoreceptor for revealing another imagewise voltage to be developed with magenta toner.
