Abstract

Patente de Invenção: "MéTODO PARA A PREVISãO DE MUDANçAS NA RELAçãO DE TONER PARA PORTADOR UM SISTEMA DE DESENVOLVIMENTO XEROGRáFICO". A invenção refere-se a um sistema de controle para desenvolvimento xerográfico, um valor importante a ser monitorado em tempo real é a relação de toner para portador (T/C) no suprimento de desenvolvedor. Entretanto, medições diretas de T/C, seja por meio de leituras de magnetómetro do desenvolvedor, ou por leituras de densitómetro de pedaços de teste desenvolvidos, tendem a ser ruidosas. Para excluir medições não usuais de T/C, após cada leitura de T/C, uma faixa provável de mudança de T/C é calculada. Se uma leitura de T/C subseq³ente não estiver nesta faixa provável, a leitura é substituída por um limite superior ou inferior da faixa provável calculada.
