Seaory S-Series Firmware Update (Windows & Mac) — S25/S26/S28

Updated October 12, 2026

Use the firmware package for your exact Seaory S25, S26 or S28 model. Follow the updater until it reports completion, then confirm the installed version. The time required can vary.

When to update: on every new printer, right after the driver is installed and the printer is connected, and before you print real cards.

Quick Answer (Windows and Mac)

Windows: Download and extract firmware → open FwUpdateTool.exe → click Update Firmware → when you see “Firmware Update Done”, close and confirm in Printer Preferences → Printer Information.

Mac: Unzip firmware → place FwUpdateTool.app inside the model’s firmware folder → connect printer → open the tool → click Upgrade Firmware → wait for Finished.

Don’t power off or disconnect the printer while updating. The S25 uses USB; Ethernet connections apply to S26/S28.

Current model downloads: S25 support · S26 support · S28 support.
