What to do if my Brother MFC-8520DN All in One Printer displays 'Cover is Open'?
- D
  Donna MooreSep 1, 2025
  The 'Cover is Open' error on your Brother All in One Printer means that a cover is not completely closed. This could be the front cover, the ADF cover, or the fuser cover. Make sure that all covers are completely closed. If you are loading a document, close the ADF cover, then press Stop/Exit. If the fuser cover is the issue, also ensure no paper is jammed behind it.

Why does my Brother MFC-8520DN All in One Printer say 'Cooling Down Wait for a while'?
- D
  David CrawfordSep 1, 2025
  The 'Cooling Down Wait for a while' message on your Brother All in One Printer appears because the temperature of the drum unit or toner cartridge is too high. Ensure the fan in the machine is spinning and the exhaust outlet is not blocked. If the fan is spinning, clear any obstructions around the exhaust. If the fan isn't spinning, disconnect the machine from power for a few minutes, then reconnect it.
