Abstract
UN APARATO REVELADOR (29) PARA USO EN UN APARATO DE REPRODUCCION ELECTROESTATICA INCLUYE UN GRAN DEPOSITO DE COLOR ORGANICO (34,44). EL COLOR ORGANICO ESTA SITUADO EN UNA CAMARA DE SUMINISTRO (39) Y SE MIDE PARA UNA CAMARA DE RODILLO REVELADOR (35) DESDE LA CUAL ES TRANSPORTADO POR UN RODILLO REVELADOR (31) PASANDO POR UNA HOJA RASCADORA DE CILINDROS (36) HASTA UN TAMBOR FOTOCONDUCTOR (19) PARA REVELADO DE IMAGEN. UN RODILLO DE MEDICION DE COLOR ORGANICO (41) GIRA CON EL RODILLO REVELADOR (31) PARA PROPORCIONAR UN SUMINISTRO CONTINUO DE COLOR ORGANICO DE LA CAMARA DE SUMINISTRO (39) HASTA LA CAMARA DEL REVELADOR (35). UNA VEZ QUE SE ALCANZA UN NIVEL DE EQUILIBRIO (65), EL RODILLO DE MEDICION DE COLOR ORGANICO (41) ACTUA PARA ELIMINAR EL COLOR ORGANICO (34) DESDE LA CAMARA DEL REVELADOR (35) HASTA LA CAMARA DE SUMINISTRO (39) PARA ASEGURAR UN FUNCIONAMIENTO APROPIADO DEL RODILLO REVELADOR (31).
