What’s the very first thing you do when promoting or recycling a gadget? Reset your knowledge, after all — no one needs their private data stepping into another person’s palms. But a regular reset isn’t sufficient for some Canon printers, apparently. In a latest assist submit, the corporate informed house owners that the usual knowledge reset operate doesn’t really do away with all of the printer’s saved knowledge, notably leaving your native Wi-Fi SSD and password intact if you happen to’ve set them up. Hundreds of fashions are affected within the E, G, iB, M, T, X, and Pro sequence of shopper and business printers.

“Sensitive information on the Wi-Fi connection settings…may not be deleted by the usual initialization process,” Canon warns in a short post (noticed by Ars Technica). Users are instructed to make use of the “Reset all” operate within the Settings menu, then activate the Wi-Fi connection, then go again into the reset sub-menu and clear it once more. The course of is barely totally different on some fashions — if there’s no devoted software program reset menu, clear the LAN settings, activate Wi-Fi, then clear the LAN settings once more.

Based on the considerably roundabout means of fixing this concern, it appears like a software program bug moderately than an intentional retention of person knowledge. That’s one thing that Canon would possibly have the ability to repair with a firmware replace over Wi-Fi, since, you understand, the printer’s already related to the native community.) Just as long as it doesn’t brick them, like a recent HP firmware update did.
