Abstract: When calibrating a transfer assist blade (TAB) in a printer, toner patches are formed on a photoreceptor belt in the printer at locations between sheets of paper. The TAB is partially deployed between paper sheets to pick up toner, and then deployed normally or with a delay to mark the back sides of the sheets. A processor evaluates distances between TAB touchdown and liftoff points and leading and trailing edges of the sheets, and calibrates the TAB to optimize the TAB timing. Additionally, test prints can be generated, each having slightly varied TAB calibration settings that are stored in a non-volatile memory (NVM) table. A user enters an identification number for a test print with the best calibration settings. The processor looks up calibration settings corresponding to the entered identification number and moves NVM settings from the table into operational locations in the system NVM to calibrate the printer.
