Eight years or so have passed since the Paper & Printing Machinery Service Center was established by Mitsubishi Heavy Industries, Ltd. (MHI) in October 1994 for the purpose of strengthening the service system so as to be close to customers. Since then, MHI has offered various levels of prompt and efficient services to suit the equipment maintenance systems of customers ranging from major newspaper publishing companies and printing companies through to customers who have purchased just one unit of printing machinery. MHI's customer service has been performed mainly by this Service Center through its distributors and selling agents at home and abroad. Upon publication of this article on the Mitsubishi Heavy Industries Technical Review, MHI will be grateful if every customer will take this opportunity of understanding MHI's desire to provide good service, and giving their opinions and suggestions on this article.
