Explanation 1. Note
The software will update the printer’s firmware. – Printers for the EEB and EME regions: It cannot be downgraded to Ver. 13.09 or earlier after the firmware is upgraded to Ver. 13.10 or later.
The update may take up to 20 minutes. It cannot be interrupted until the update is complete. – The software has the downgrade protection function. Therefore, once you update the firmware to Ver. 13.00 or later, you will not be able to revert to a version earlier than Ver. 13.00. – Updating via Bluetooth may take up to 90 minutes and is not recommended.
If you update the firmware using this updater, the automatic connection function of the cloud service for utilizing Epson receipt printers is set to [Enable]. Therefore, the serial number of a printer is automatically uploaded to the Epson server when the printer connects to the Internet. If you want to prevent the serial number from being uploaded automatically, refer to the Announcement file (Announcement_sht_for_FWUpdater_ww_01.pdf) to disable this setting.
Note the following points while updating as the product may be damaged: – Do not turn off the product’s power. – Do not unplug the connection cable or the power cable. – If an error occurs during the update, check the connection to the printer and be sure to run the update again using this software.
Depending on the usage environment, updating the firmware might cause faulty printer operations. Before updating the firmware, confirm with the printer seller or SI and others if there is no problem with updating it.
