When it comes to selling or recycling gadgets, a crucial step is resetting the device to ensure that personal information remains private — However, Canon printer owners recently received a surprising revelation: a standard data reset may not be sufficient to clear all stored information from their printers, particularly Wi-Fi connection data.
Canon has acknowledged this issue in a support post, alerting users that specific models across their consumer and commercial printer series retain Wi-Fi SSID and password information even after performing a standard initialization.

The affected Canon printer models belong to the E, G, iB, M, T, X, and Pro series. Despite initiating a standard data reset, which is intended to wipe out all user data, sensitive Wi-Fi connection settings remain intact.
This means that if you’ve previously configured your printer to connect to a local Wi-Fi network, the SSID and password may still be accessible to anyone who gains access to the printer.
Additional Steps Required for Complete Data Clearing
To address this privacy concern, Canon advises users to take additional steps to ensure a thorough reset. After performing the standard initialization process, users are instructed to utilize the “Reset all” function available in the printer’s Settings menu.
Once that’s done, users need to turn on the Wi-Fi connection and then return to the reset sub-menu to perform another data-clearing process. However, it’s worth noting that the procedure may vary slightly depending on the printer model. For some models without a dedicated software reset menu, the process involves clearing the LAN settings, enabling Wi-Fi, and then clearing the LAN settings again.
Software Bug or Firmware Update Solution?
The convoluted process for clearing Wi-Fi connection data suggests that this issue might be a software bug rather than a deliberate retention of user information. Canon could potentially address this problem with a firmware update delivered over Wi-Fi since the printers are already connected to the local network. However, the company must exercise caution to avoid any unintended consequences, such as rendering the printers inoperable, as seen in a recent HP firmware update incident.
In an age of increasing digital connectivity, data privacy is a significant concern for users. Manufacturers, like Canon, must ensure that their products uphold robust data security standards. With the reliance on internet connectivity, printers have become potential points of vulnerability. Addressing and resolving issues like retained Wi-Fi information is crucial to maintaining user trust and safeguarding their sensitive data.
Canon’s acknowledgment of certain printer models retaining Wi-Fi connection data even after a reset highlights the importance of thorough data-clearing processes. Users are advised to follow the recommended steps provided by Canon to mitigate the privacy risk effectively. Furthermore, Canon’s commitment to promptly addressing this issue with a firmware update demonstrates its dedication to maintaining the privacy and security of its customers’ information.
