Abstract

"DISPOSITIVO DE CARREGAMENTO XEROGRáFICO QUE TEM DOIS SISTEMAS DE PINO". Em um aparelho de impressão xerográfica um escorotron aplica uma carga uniforme sobre um fotorreceptor para formar imagens eletrostáticas latentes. Dois sistemas de pino condutores são colocados em uma carcaça definida por paredes laterais e uma grade adjacente ao fotorreceptor. Para cada sistema a distância até a parede lateral adjacente é 1,0 até 1,5 a distância até a grade.
