Abstract

UN SISTEMA PERFECCIONADO DE GRABACION DE IMAGENES DE EJES DE MEDIOS PARA UN APARATO REGISTRADOR/IMPRESORA (10) DE CHORRO DE INYECCION DE TINTA, DE COLORES MULTIPLES. EL SISTEMA COMPRENDE UN CONJUNTO DE CARRO (100) PARA RETENER CARTUCHOS (102, 104, 106, 108) DE CHORROS DE TINTA MULTIPLES, O ESTILETES. CADA CARTUCHO (102, 104, 106, 108) TIENE UNA PLURALIDAD DE BOQUILLAS (502, 504, 506, 508), ADAPTADAS PARA EXPULSAR TINTA EN RESPUESTA A LA APLICACION A LOS MISMOS DE UNA SEÑAL ELECTRICA. SE DISPONE DE UN PRIMER MECANISMO (112), PARA DESPLAZAR EL CONJUNTO DEL CARRO (100) EN UN PRIMER EJE (EXPLORACION). SE DISPONE DE UN SEGUNDO MECANISMO (152) PARA DESPLAZAR MEDIOS DE IMPRESION (30) EN UN SEGUNDO EJE (MEDIOS), TRANSVERSAL AL PRIMER EJE. UN CODIFICADOR DE POSICIONES (152) DETECTA LA POSICION DEL CONJUNTO DEL CARRO EN EL EJE DE MEDIOS. UN CIRCUITO (300) DE CONTROL PROPORCIONA SEÑALES ELECTRICAS QUE HACEN QUE LAS BOQUILLAS (502, 504, 506, 508), EN LOS CARTUCHOS DE CHORRO DE TINTA (102, 104, 106, 108), EXPULSEN TINTA SOBRE LOS MEDIOS (30) Y CREEN UNA IMAGEN SOBRE LOS MISMOS EN FORMA DE UN PATRON DE PRUEBAS (40), EN RESPUESTA A SEÑALES DE TEMPORIZACION. EL SISTEMA DE LA INVENCION INCLUYE UN MODULO SENSOR (200), QUE DETECTA OPTICAMENTE LA IMAGEN Y PROPORCIONA UN CONJUNTO DE SEÑALES DETECTADAS EN RESPUESTA A LA MISMA. LAS SEÑALES DETECTADAS SE MUESTREAN, DE CONFORMIDAD CON LAS SEÑALES DEL CODIFICADOR DE POSICIONES, PARA PROPORCIONAR SEÑALES DE TEMPORIZACION CORREGIDAS. EN UNA VERSION ESPECIAL, EL PATRON DE PRUEBAS (140) SE ILUMINA POR UNA FUENTE DE LUZ (232), EN EL MODULO SENSOR (200). LA FUENTE DE LUZ (230) TIENE UNA ENERGIA ESPECTRAL EN LAS BANDAS DE COLORES DE INTERES. EL PATRON DE PRUEBAS (40) INCLUYE UNA PLURALIDAD DE BARRAS VERTICALMENTE ESPACIADAS QUE, CUANDO SON EXAMINADAS POR EL MODULO SENSOR (200), PERMITEN QUE EL MODULO (200) GENERE UNA SEÑAL DE SALIDA DE UNA FRECUENCIA DADA. LA SEÑAL DE SALIDA SE MUESTREA Y PROCESA, PARA PROPORCIONAR LAS SEÑALES DE TEMPORIZACION CORREGIDAS, PARA LA ACTIVACION DE LAS BOQUILLAS. MEDIANTE LA DETECCION DE LA POSICION DEL PATRON (40), PUEDE CORREGIRSE LA FALTA DE ALINEAMIENTO DE UN ESTILETE EN PARTICULAR.A PERFECTED MEDIA AXIS IMAGE RECORDING SYSTEM FOR A MULTIPLE COLOR INKJET RECORDER / PRINTER (10). THE SYSTEM INCLUDES A CART SET (100) TO RETAIN CARTRIDGES (102, 104, 106, 108) OF MULTIPLE INK JETS, OR STYLES. EACH CARTRIDGE (102, 104, 106, 108) HAS A PLURALITY OF NOZZLES (502, 504, 506, 508), ADAPTED TO EJECT INK IN RESPONSE TO APPLICATION TO THEMSELVES OF AN ELECTRICAL SIGNAL. A FIRST MECHANISM (112) IS AVAILABLE TO MOVE THE TROLLEY ASSEMBLY (100) ON A FIRST AXIS (EXPLORATION). A SECOND MECHANISM (152) IS AVAILABLE TO MOVE PRINTING MEDIA (30) ON A SECOND AXIS (MEDIA), CROSS-CUTTING TO THE FIRST AXIS. A POSITION ENCODER (152) DETECTS THE POSITION OF THE CAR ASSEMBLY ON THE MEDIA AXIS. A CONTROL CIRCUIT (300) PROVIDES ELECTRICAL SIGNALS THAT MAKE THE NOZZLES (502, 504, 506, 508), IN THE INK JET CARTRIDGES (102, 104, 106, 108), EJECT INK OVER THE MEDIA (30) AND THEY CREATE AN IMAGE ABOVE THEM IN THE FORM OF A TEST PATTERN (40), IN RESPONSE TO TIMING SIGNALS. THE SYSTEM OF THE INVENTION INCLUDES A SENSOR MODULE (200), WHICH OPTIMALLY DETECTS THE IMAGE AND PROVIDES A SET OF SIGNALS DETECTED IN RESPONSE TO IT. DETECTED SIGNALS ARE DISPLAYED, IN ACCORDANCE WITH THE POSITION ENCODER SIGNALS, TO PROVIDE CORRECTED TIMING SIGNALS. IN A SPECIAL VERSION, THE TEST PATTERN (140) IS ILLUMINATED BY A LIGHT SOURCE (232), IN THE SENSOR MODULE (200). THE LIGHT SOURCE (230) HAS A SPECTRAL ENERGY IN THE BANDS OF COLORS OF INTEREST. THE TEST PATTERN (40) INCLUDES A PLURALITY OF VERTICALLY SPACED BARS WHICH, WHEN EXAMINED BY THE SENSOR MODULE (200), ALLOW THE MODULE (200) TO GENERATE AN OUTPUT SIGNAL OF A GIVEN FREQUENCY. THE OUTPUT SIGNAL IS SAMPLED AND PROCESSED, TO PROVIDE THE CORRECTED TIMING SIGNALS, FOR THE ACTIVATION OF THE NOZZLES. THROUGH THE DETECTION OF THE POSITION OF THE PATTERN (40), THE LACK OF ALIGNMENT OF A PARTICULAR STYLE CAN BE CORRECTED.
