发明名称 System and method for conveying printer status information
摘要 Systems and methods for conveying printer status information to a user are provided. One or more moving light sources are selectively illuminated to convey printer status information to the user and to attract the user's attention. Different illumination states correspond to different printer status and configuration information. The light source may be part of an optical sensor. In this manner, the light source may have dual functions: (1) to illuminate the print media during a calibration operation performed by the optical sensor; and (2) to selectively illuminate during a printing operation to convey printer status information to the user.
