Abstract

Patente de Invenção: <B>"CONTROLE DE CONCENTRAçãO DE TONER DE REALIMENTAçãO PARA UM SISTEMA DE GERAçãO DE IMAGENS"<D>. A presente invenção refere-se, de forma geral, a um sistema de geração de imagens, e mais especificamente, a um método e aparelho para predizer com precisão o uso do toner e portanto as exigências de distribuição do toner em um sistema de geração de imagens, Mais particularmente, a presente invenção refere-se a um sistema de controle de concentração de toner para manter a concentração de toner em uma estrutura reveladora, que é unida em um distribuidor contendo toner. O sistema de controle de concentração de toner compreendendo: um sensor, lendo a concentração de toner; recursos para determinar uma correção da concentração de toner lida pelo sensor com base nos desvios da temperatura nominal e indutância nominal na estrutura reveladora; recursos para ajustar um alvo de concentração do toner com base na correção; e recursos para gerar um comando de distribuição de realimentação com base no alvo ajustado de concentração de toner para distribuir toner para dentro da estrutura reveladora para manter a concentração de toner na estrutura reveladora.
