    • Imaging devices and methods of operating imaging devices that facilitate reducing nonvolatile storage needs of the imaging devices. The imaging devices are adapted to request control programs from external devices. Control programs are received on a communication input of the imaging device and stored on a volatile storage media for use by a processor of the imaging device. The embodiments can also facilitate more reliable updating within a networked system in that updating an image of a control program on one network device can automatically lead to updating of multiple imaging devices, thus eliminating a need to individually update each imaging device. A default control program is used if no control program is received on the communication input within a predetermined timeout period.
    • 成像装置和操作成像装置的方法,其有助于减少成像装置的非易失性存储需求。 成像设备适于从外部设备请求控制程序。 控制程序在成像设备的通信输入端被接收并存储在易失性存储介质上,供成像设备的处理器使用。 这些实施例还可以促进在网络化系统内的更可靠的更新,因为在一个网络设备上更新控制程序的图像可以自动地导致更新多个成像设备,从而消除了对每个成像设备进行单独更新的需要。 如果在预定的超时期间内没有在通信输入上接收到控制程序,则使用默认控制程序。
