Uploading And Downloading Backup Data; Outline - Canon iR4570 Series Service Manual

Chapter 17
You will not be able to download G3Fax twice in succession. (Once downloading is executed, the board will be reset,
causing download mode to end.)
Be sure never to turn off the machine while it is executing a downloading session or writing downloaded system
software. Otherwise, the write operation (to the flash ROM DIMM of the G3 fax board) may fail, preventing board
functions. In the event the board fails to function, be sure to replace the flash ROM DIMM found on the G3 fax board.

- If you are replacing the HDD or executing 'ALL' or 'APL_MEP', you can temporarily set aside MEAP applications
by uploading MeapBack before execution and downloading it after execution.
- Only the machine uploaded can download SramImg and MeapBack.
