Shopping for the copier? For the second consecutive year, Imagistics copiers topped J.D. Power and Associates' survey of customer satisfaction. By introducing new models and better training its sales force, Hewlett-Packard jumped from last place in 2003 to a tie with Toshiba for second in 2004. Only a few points on a 1,000-point scale separated the top copier companies in the survey of business decision- makers. A key strength among the greatest: sales reps who understand customers' needs and which product will best suit them.
