An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a driven toner distributing member that distributes accumulated toner within the container. The toner distributing member may be driven by a shared speed-controlled motor that further drives an image forming process member. The waste toner system may detect the accumulation of waste toner by monitoring a drive control circuit while the toner distributing member is being driven. For example, a logic circuit may detect the accumulation of waste toner based on monitoring a predetermined frequency of interest of a frequency domain transform of a motor control signal, the frequency of interest associated with the shared motor driving the toner distributing member.

Methods and systems for automated display of music data in a music display system. In one embodiment, a method for distinguishing lyrics and notations of a music data file is provided. In one embodiment, the lyrics are automatically shown in a different color or other display appearance relative to the notations. In another embodiment, the key of the notations is automatically determined and stored and/or displayed. In another embodiment, zoom in and zoom out capability is provided by automatically changing the font to appropriate permitted sizes, and/or by automatically determining the relative pixel spacing of the words in the lyric lines and the musical notation lines in the corresponding musical notation lines and selecting a font that maintains adequate spacing. Other inventive music display file presentation, storage, and analysis capabilities and features also are disclosed.
