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.
