Abstract:
The user of an electronic device can easily know when a replaceable unit needs replacing (the service life). A host computer 100 connected to a media processing device 1 (electronic device) executes a step (S4) of acquiring maintenance counter information that is stored in the media processing device 1, steps (S5, S7) of calculating based on the acquired maintenance counter information A=(the total open/close count of the media tray of the media drive 41 (51))/(an assured media tray open/close count), B=(the cumulative CD writing time of the media drive 41 (51)/(the assured CD writing time), and C=(the cumulative DVD writing time) of the media drive 41 (51)/(the assured DVD writing time), and steps (S6, S8) of displaying the maximum value of values A, B, and C as the expected service life of the media drive 41 (51) on a display unit.
