Abstract

UN SISTEMA DE DETECCION DE NIVEL BAJO DE TINTA (30) SE COMBINA CON UN SISTEMA DE DETECCION DE CARTUCHO DE TINTA PARA HACER POSIBLE UNA IMPRESORA DE CHORRO DE TINTA MAS EFICIENTE. UN CONTENEDOR DE TINTA (16) QUE SUMINISTRA TINTA A UNA CABEZA DE IMPRESION ASOCIADA (18) SE MODIFICA MEDIANTE LA INCORPORACION DE DOS ELEMENTOS DE DIRECCIONAMIENTO DE LUZ (21, 22), EN LA REALIZACION PREFERIDA UN PRISMA DE FACETAS (22A, 22B) Y UN ESPEJO DE TECHO (21A, 21B), DENTRO DE UNA PARED TRANSPARENTE DEL ALOJAMIENTO DEL CONTENEDOR. EL CARTUCHO (10), QUE COMPRENDE EL CONTENEDOR DE TINTA (16) Y LA CABEZA DE IMPRESION ASOCIADA (18), SE MONTA SOBRE UN CARRO DE BARRIDO. PERIODICAMENTE, EL CARRO (12) ES TRANSPORTADO HASTA UNA ESTACION DE DIRECCION (30) QUE COMPRENDE UN PAR DE FUENTES DE LUZ (34, 36) Y FOTODETECTORES DE USO COMUN (38). SE ACTIVA UNA PRIMERA FUENTE DE LUZ (34) Y EL RAYO DE LUZ SE DIRIGE HASTA UNA UBICACION EN LA QUE EL ESPEJO DE TECHO (21) DEBERIA ESTAR POSICIONADO SI ESTUVIERA PRESENTE EL CARTUCHO (10). SI EL CARTUCHO ESTA AUSENTE, SE DETECTA LA PERDIDA DE UNA SEÑAL DE RETORNO REFLEJADA, QUE INDICA QUE EL CARTUCHO NO HA SIDO INSERTADO. LA OPERACION DE IMPRESION SE RETIENE HASTA QUE EL CARTUCHO (10) HAYA SIDO INSERTADO. SI EL CARTUCHO SE INSERTA DE FORMA APROPIADA, EL ESPEJO DE TECHO (21) DEVUELVE LA MAYORIA DE LA LUZ INCIDENTE HACIA EL FOTODETECTOR (38) QUE GENERA UNA SEÑAL INDICATIVA DE LA PRESENCIA DEL CARTUCHO (10). ENTONCES SE ACTIVA UNA SEGUNDA FUENTE DE LUZ (22) Y SE DIRIGE HACIA EL PRISMA DE FACETA (22A, 22B), QUE ESTA BIEN SUMERGIDO EN LA TINTA O EXPUESTO AL AIRE DENTRO DEL INTERIOR DEL CONTENEDOR (16). SI OCURRE ESTO ULTIMO, LA LUZ ES INTERNAMENTE REFLEJADA POR LAS FACETAS DEL PRISMA DE NUEVO HACIA EL FOTODETECTOR (38). SI SE ESTA REALIZANDO UNA OPERACION DE IMPRESION, Y EL NIVEL DE TINTA HA CAIDO, EL FOTODETECTOR COMUN DETECTA UN COMPONENTE DE LUZ REDIRIGIDO FUERTE O DEBIL E INICIA UNA COMPROBACION DE ESTADO Y GENERA UN AVISO APROPIADO DEL NIVEL BAJO DE TINTA O DE LA FALTA DETINTA.
