Abstract
A system of diagnosing a printer or photocopying system using a flexible diagnostic sheet is described. In the system, a thin diagnostic sheet including a plurality of sensors formed on the sheet is run through the paper path of the printing system. The printing system subjects the diagnostic sheet to the printing process, including the deposition of fuser oil and toner on the sheet. Sensors on the sheet record various parameters, including but not limited to the amount of fuser oil deposited and the charge on various toner particles. The information is transmitted to service personnel or the printer end user to enable timely repair of the printer.
