Abstract

"SISTEMAS E MéTODOS PARA CORRIGIR DEFEITOS DE DIVISãO EM FAIXAS UTILIZANDO CONTROLE DE ALIMENTAçãO PARA TRáS E/OU DE ALIMENTAçãO PARA FRENTE". A presente invenção refere-se a sistemas e métodos para controlar defeitos de divisão em faixas em um membro de recepção em um processo de produção de imagem ou de impressão utilizando uma técnica de controle de alimentação para trás e/ou de alimentação para frente. Em uma modalidade ilustrativa, um método para controlar defeitos de divisão em faixas em um membro de recepção em um processo de produção de imagem ou de impressão inclui (a) determinar uma densidade de toner no membro de recepção, (b) automaticamente determinar a extensão da divisão em faixas no membro de recepção ao comparar a densidade de toner determinada com um valor de densidade de toner de referência e (c) automaticamente ajustar a densidade do toner com base em um resultado obtido a partir da comparação da densidade medida do toner com o valor de densidade de toner de referência, automaticamente determinar a extensão da divisão em faixas e automaticamente ajustar a densidade do toner sendo executados utilizando uma rotina ou aplicação de controle de alimentação para frente e/ou de alimentação para trás.
