Abstract
A quality check of the photoconductive belt of an electrographic print engine may be performed by writing a toner image on each of the virtual image frames of the loop and printing out those images. The printer user interface may provide a test screen to prompt a user to perform such a quality check. To facilitate the printing of sample receivers for each frame of a printer's film loop a user button is provided at the user interface. When selected, this signals the marking engine to schedule for print an appropriate number of receivers such that each frame on the film belt will be printed on. Each receiver may be a duplicate copy of a particular receiver in the currently printing job.
