Abstract

"AJUSTE DE MìDIA DE IMPRESSãO UTILIZANDO RASTREAMENTO ATIVO DE ROTAçãO DE ROLDANA LIVRE". A presente invenção refere-se mais precisamente a corrigir a posição e desvio de folha em uma trajetória desejada de folha de meio de impressão em um caminho de papel de impressora, com um sistema de registro que inclui prendedores de tração de folha definidos por roletes de tração de folha por fricção com superfície de elastómero acionados diferencialmente e espaçados lateralmente e roletes livres não acionados associados possuindo um engate de folha rotacional sem deslocamento. Os roletes livres não acionados possuem codificadores rotativos produzindo sinais do codificador correspondendo à sua rotação por uma folha no prendedor, sinais do codificador estes que são fornecidos a um controlador para o sistema de ajuste para controlar sistemas de motor de acionamento diferencial e para frente para os roletes de tração de folha de modo a substancialmente corrigir erros na trajetória desejada da dita folha pelas forças de arrasto de folha atuando nos roletes de tração de folha com superfície de elastómero nos prendedores de tração de folha.
