Control Panel Methods

There are several Control Panel configurations that support configuring the Remote Firmware Upgrade settings.

Products with a color touch screen, two line LCD display or graphical LCD

1. Select Setup menu.

2. Select Service.

3. Select RFU.

   ON– allows a firmware update to be downloaded to the printer

   OFF– refuses firmware updates (can be changed to ON from within the firmware update utility)

   OFF AND LOCKED– refuses firmware updates (can only be changed to ON from the product control panel)

总结：M1136这个机器，还有cp 1025，控制面板是最基本的2位数字的面板，都没有菜单，这个机器也没有网络功能，没什么能调整的。正常有控制面板的机器，菜单里也没有rfu 的选项，这个不是普通选项，不会出现在菜单里，RFU这个一般是主板的选项。用户遇到这种情况，建议直接联系维修站来解决。
