I've been asked about disposing of a Brother all-in-one printer MFC-6490CW. The machine has been used in an office setting for copying, printing, and faxing sensitive data. From what I can find online, it seems this model doesn’t have a traditional internal hard drive that can be removed like a regular commercial copier. I thought it would be helpful to check if anyone knows a safe way to erase any stored information before disposal without causing significant damage.
Printing a fax from the Fax Storage memory removes it from memory automatically. You can also remove stored faxes by using these steps: Select MENU or MENU/SET, then choose Fax => Remote Fax Opt => Fwd/Page/Store or Forward/Store. Use the UP OR DOWN ARROW key to select Off. Press OK or MENU/SET. Your Brother machine's LCD will prompt you with the following question: Erase All Fax (Doc) ? 1. Yes 2. No
The device retains only firmware on a tiny flash chip and limited rewritable memory for tracking details like scanned pages, printed output, and laser operation duration. The printer includes 64 MB of RAM, functioning as its main storage. When powered off, data vanishes almost instantly. For recovery steps, refer to the service manual at the provided link. If concerned, you can physically damage the chip by hitting it with a hammer on page 109 or inspecting the board for disassembly guidance on page 180.
I would send faxed copies of scans that exceed 64Mb, printing and copying them. This ensures nothing remains stored in memory unless the current task requires it. Keep in mind not every device supports this feature. A photo is preferable since it uses less paper for printing. Destroying the chip offers the highest security, though it means disposing of it in a landfill rather than selling it for profit.
