Abstract:
An electrostatographic printing apparatus comprises a charge receptor (10), and a transfer station for transferring a toner image from the charge receptor (10) to a sheet (S). The sheet passes through a nip formed between the charge receptor (10) and a moving transfer belt (30). Upstream of the nip, the belt (30) forms a shallow angle relative to the charge receptor (10), downstream of the nip, the belt (30) forms a steep angle relative to the charge receptor (10). This configuration enables self-stripping of the sheet from the transfer belt at the exit of the nip.

Abstract:
Un aparato de impresion electrostatografica comprende un receptor de carga, y una estacion de transferencia para transferir una imagen de pigmento organico del receptor de carga a una hoja. La hoja pasa a traves de una linea de contacto formada entre el receptor de carga y una banda de transferencia movil. Corriente arriba de la linea de contacto, la banda forma un angulo agudo en relacion al receptor de carga; corriente abajo de la linea de contacto, la banda forma un angulo agudo en relacion al receptor de carga. Esta configuracion permite la separacion automatica de la hoja de la banda de transferencia en la salida de la linea de contacto.
Abstract:
sistema e método para preparação de superfície de imagem em uma impressora jato de tinta aquosa. uma impressora jato de tinta aquosa é provida com um aplicador de energia de superfície que é posicionada para tratar a superfície de uma manta imediatamente antes de uma tinta de ejeção de cabeça de impressão sobre a manta. modificar a energia de superfície da manta com o campo elétrico e partículas carregadas produzidas pelo aplicador afeta a adesão da tinta à manta. esta mudança de adesão a partir do impacto da tinta na manta até a imagem de tinta é transferida ao meio. o aplicador de energia de superfície é operado durante cada ciclo de impressão para alterar a energia de superfície da manta para cada imagem de tinta formada na manta
Abstract:
Se proporciona una impresora de chorro de tinta acuosa con un aplicador de energía de superficie que está colocado para tratar la superficie de un lienzo inmediatamente antes de que la cabeza de impresión expulse tinta sobre el lienzo. La modificación de la energía de superficie del lienzo con el campo eléctrico y las partículas cargadas producidas por el aplicador altera la adhesión de la tinta al lienzo. Esta adhesión cambia a partir del impacto de la tinta sobre el lienzo hasta que la imagen de la tinta se transfiera al medio. El aplicador de energía de superficie es operado durante cada ciclo de impresión para alterar la energía de superficie del lienzo para cada imagen de tinta formada sobre el lienzo.

Abstract:
An electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet by providing an electric field of predetermined magnitude at a transfer zone. The transfer station includes a rotatable transfer member, with a cleaning corotron associated therewith. A control system for maintaining a constant current at the transfer zone takes into account a current supplied by the cleaning corotron. The control system can also take into account current leakages associated with the transfer member.
Abstract:
PROBLEM TO BE SOLVED: To provide a BCR system which has superior charge uniformity and less wear, and which is more inexpensive. SOLUTION: A biased charge roller (BCR) 1 is constituted, by arranging many electrodes on an insulating substrate layer 10 and covering them with a semiconductor layer 9. The electrodes 8 are applied with bias voltages VP PRE-NIP and V POST-NIP from power sources 14 and 15 so that, for example, an electrode group belonging to a pre-nip region 6 (and an in-nip region 3) and an electrode group belonging to a post-nip region 7 are biased with the different bias voltage. Forms of electric charges to a photoreceptor surface 2 in the in-nip region 3, the pre-nip region 6, and the post-nip region 7 are optimized by the arrangement and sizes and shapes of the electrode, voltage settings, etc. Electrode 8 may be arranged inside the insulating substrate layer 10 and inside the semiconductor layer 9.
