Preparing an SD Card

The Focus Premium Max, Focus Premium and Focus Core exports recorded scans on a removable SD card. This memory card can also be used to create backups of the scanner settings, to import scanner settings, and to install firmware updates.

SDHC or SDXC cards are highly recommended. Memory cards with a size up to 512 GB have been verified to operate with the scanner. The speed of the card must be Class 10/V30 or better.

The SD card must be formatted in the exFAT file system. When using an SD card other than one supplied with the scanner, format it with the scanner format function first. See Service.

SDHC cards may also be formatted with Windows. SDXC cards with a capacity of more than 32 GB cannot be formatted with the Windows format function, because Windows formats them in its own file system. The Windows file system is not supported by the scanner. There are freeware tools that allow formatting these cards with Windows as exFAT, but we strongly recommend using the scanner’s format function.

Risk of data loss.
Do not remove the SD card from the scanner while it is busy, otherwise you risk corrupting the data on the card. A busy SD card is indicated by the SD card icon blinking in the status bar of the Focus user interface. It is safe to remove the card from the scanner when this icon has disappeared.

When removing a Focus SD card from your computer, always use the Safely Remove Hardware option from the Windows system tray, otherwise you risk corrupting the data on the SD card. To safely remove hardware in Windows, right-click in the system tray, double-click Safely Remove Hardware in the context menu, then select the device you want to remove.
