Les utilisateurs d’imprimantes photo Canon peuvent supprimer manuellement les paramètres Wi-Fi avant de les jeter
 
Canon issued a bulletin on Monday reminding printer owners to manually delete Wi-Fi wireless network settings stored in their printers before selling, discarding or servicing them to prevent sensitive information from falling into the wrong hands.

The notice states that the wireless network connection settings in the printer may not be deleted by the normal initialization process. These settings include information such as the wireless network name, password, type, local network IP address, MAC address, and network configuration. If this information is exposed, bad actors could use it to illegally gain access to the network the printer is connected to.

Canon recommends that printer users follow the steps below to manually clear the wireless network settings before handing over the printer to any third party:

Pour les imprimantes dotées d’une fonction de réinitialisation dédiée, les utilisateurs doivent :

Reset all settings (Reset Settings -> Reset All)

Enable Wi-Fi

Reset all settings again

Pour les imprimantes qui ne disposent pas d’une fonction de réinitialisation dédiée, les utilisateurs doivent :

Reset LAN settings

Enable Wi-Fi

Reset LAN settings again

Canon said that nearly 200 printer models are affected, and the specific list can be viewed here.
