Abstract

A diagnostic system made part of or for use with a document handling device in which a customer is guided toward performance of at least one comparison means in a diagnostic routine analysis. The comparison means is selected from a group comprising (1) a first comparison comparing a fused print media and an unfused print media for presence of a defect, (2) a second comparison comparing an output print media and at least one image on a screen for a type of defect, and (3) a third comparison comparing a low-charged print media and a no-charged print media for qualities of the defect. The customer enters a selection based on results of the first, the second, or the third comparisons. The diagnostic system can identify a part causing a defect in the print media based on results of the comparisons.
