Preparation
• Conditions for USB memory which can be used for updating the firmware are as follows:
- USB flash memory compatible with the USB (1.1/2.0/3.0) interface
The speed is limited to USB2.0 specifications even if using a device that supports
USB3.0
- The USB memory is formatted in FAT32 format
- No security functions such as encryption and password lock have been added (or the
USB memory allows its security functions to be turned OFF)
- We recommend that you use a memory device with no more than 32 GB of capacity
- USB flash memory that appears as multiple drives on a computer cannot be used
• If the USB port at the right side of the MFP control panel is not available, remove the
upper rear cover of this machine, and connect the USB extension cable to the USB port
on this machine. Besides, after rewriting the firmware, disconnect the USB extension
cable from this machine as soon as possible, and make sure that the USB port at the
right side of the MFP control panel is invalid.
