2. Prepare USB flash drive: You need an available USB flash drive to store firmware files and transfer them to the copier. Make sure that the USB flash drive is formatted as a FAT32 file system and does not contain any important data.
3. Copy the firmware file to the U disk: copy the downloaded firmware file to the prepared U disk root directory. Make sure that only firmware files are copied, without any other files or folders.
4. Enable the firmware upgrade mode on the copier: According to your copier model, find the menu or setting options on the copier control panel, and then navigate to "System Settings" or similar options. In the system settings, look for the firmware upgrade option and enable the firmware upgrade mode.
5. Connect the USB flash drive and upgrade the firmware: insert the prepared USB flash drive into the USB port of the copier. Then, follow the steps displayed on the copier control panel to upgrade the firmware. Usually, you need to browse the file system in the copier to find and select the firmware file on the USB flash drive.
6. Wait for the firmware upgrade: After selecting the firmware file, the copier will start the upgrade process. Wait for the process to be completed, and don't cut off the power or interfere with the copier.
7. Confirm that the firmware upgrade is successful: After the firmware upgrade is completed, the copier will restart and return to the normal mode. You can check the firmware version number or other firmware related information in the copier settings to confirm the firmware upgrade is successful.
