The 485 series printer uses the USB HOST port found on the back of the printer to update the firmware in the printer. A USB flash drive that is greater than 1GB but less than 32GB formatted as a FAT32 file system is used during the update. Follow the instructions below for additional information.
Preparing the USB flash drive to update printer code
- The flash drive must be less than 32GB in size and formatted as a FAT32 file system.
- Connect the USB Flash Drive to a Windows-based PC.
- Open Explorer or type My Computer in the search bar of the task menu.
- Right-click on the flash drive and select Format from the menu that appears.
CAUTION: Verify that you are selecting the flash drive as this will erase the contents of the drive. If you have any doubt, disconnect the flash drive and it should no longer show up under the Devices and Driver section.
