Abstract

"MéTODO E APARELHO PARA MEDIR A CONCENTRAçãO DE TONER". Dispositivo para medir a concentração de toner pode incluir um seletor que seleciona um tipo de material revelador a ser medido e um sensor que detecta uma quantidade de luz refletida de um material revelador. Um controlador dentro do dispositivo pode determinar um valor correspondente a uma concentração de toner do material revelador com base na quantidade de luz detectada pelo sensor.
