Na impressora multifuncional XINFLYING A2, o FAQ t\u00e9cnico orienta os t\u00e9cnicos a inspecionar as conex\u00f5es dos cabos do cabe\u00e7ote de impress\u00e3o e isolar a placa do cabe\u00e7ote, os cabos e os cabe\u00e7otes de impress\u00e3o. Outros modelos podem atribuir um significado diferente a um LED vermelho; portanto, n\u00e3o substitua uma placa com base apenas na luz.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A medida mais segura \u00e9 preservar as evid\u00eancias, desligar a impressora e realizar apenas verifica\u00e7\u00f5es externas.

Um t\u00e9cnico treinado deve seguir o procedimento espec\u00edfico do modelo para desligamento e descarga antes de inspecionar a orienta\u00e7\u00e3o do cabo, as superf\u00edcies de contato, as travas dos conectores e a profundidade de inser\u00e7\u00e3o.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O documento inclui uma medida de controle importante: inspecionar e reconectar um trecho de cabo antes de passar para o pr\u00f3ximo. Se for necess\u00e1rio remover v\u00e1rios cabos de acordo com o procedimento aprovado, identifique primeiro ambas as extremidades e suas posi\u00e7\u00f5es. Isso reduz o risco de conex\u00e3o cruzada.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Antes de restabelecer a energia, o t\u00e9cnico deve verificar se todos os cabos est\u00e3o:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Na tomada correta.<\/li>\n\n\n\n<li>Orientado corretamente.<\/li>\n\n\n\n<li>Inserido totalmente e de maneira uniforme.<\/li>\n\n\n\n<li>Fixado pelo travamento do conector.<\/li>\n\n\n\n<li>Seco e sem contamina\u00e7\u00e3o vis\u00edvel.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Nunca raspe os contatos do cabo nem os limpe com um solvente n\u00e3o aprovado. Substitua um cabo danificado apenas por uma pe\u00e7a comprovadamente compat\u00edvel com o modelo.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">T\u00e9cnico \u2013 Etapa 2: Utilize o procedimento de isolamento aprovado para o modelo<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Para o modelo A2, t\u00e9cnicos treinados podem utilizar um procedimento de isolamento no n\u00edvel da placa para determinar se o aviso se refere \u00e0 placa principal ou a um dos caminhos da cabe\u00e7a de impress\u00e3o.
