An image forming apparatus combines a plurality of sub-movies representing operation procedures to be performed to perform maintenance on the image forming apparatus and plays the combined sub-movies sequentially as one movie. In response to stopping the movie being played, the image forming apparatus displays a replay mark for use to issue a command to replay the movie from the beginning of a sub-movie corresponding to a position where the movie is stopped.

Print calibration

Methods for configuring and calibrating a printing system are described. Configuring a printing system involves obtaining data for determining a reference print element in the printing system. The reference print element is then used to determine calibration data for a given print element. The calibration data is applied for the given print element to generate a print output.
