Abstract

"IMPRESSORA DUPLEX/SìMPLEX". Um impressora duplex/símplex para produzir imagens de partícula de toner em lados opostos de um substrato durante um modo duplex ou produzir um lado de partícula de toner do substrato durante um modo duplex incluindo: dispositivo para formar uma primeira imagem de partícula de toner em um membro de representação de imagem com as partículas de toner eletrostaticamente carregadas para um primeira polaridade; um condicionador de imagem, sendo ativado somente durante o modo duplex, para reverter a polaridade da carga das partículas da primeira imagem de partícula de toner em um membro de representação de imagem; um membro intermediário para recebimento da primeira imagem de partícula de toner durante o modo duplex; um cilindro de transferência de polaridade, posicionado oposto ao membro de representação de imagem com o membro intermediário entre os mesmos, para transferir a primeira imagem para o membro intermediário por mover o membro intermediário e os membros de representação de imagem passando pelo cilindro de transferência de polaridade estando carregado na primeira polaridade durante o modo duplex, o modo duplex inclui o dispositivo de formação formando uma segunda imagem de partícula de toner no membro de representação de imagem com as partículas de toner eletrostaticamente carregadas para a primeira polaridade e o dispositivo para alimentar um substrato entre o membro intermediário e a representação de imagem e um controlador revertendo a polaridade da carga do cilindro de transferência de polaridade para uma segunda polaridade para desse modo simultaneamente transferir as partículas carregadas das primeira e segunda imagens para lados opostos do substrato durante o modo duplex.
