Brother error code 2-sided Disabled

Quick answer

The back cover is not fully closed, or the 2-sided (duplex) tray is not installed correctly, so duplex printing is disabled. Close the back cover completely and reseat the duplex tray.

Caution: This step can be done wrong in a way that is costly or hard to undo, including voiding your warranty. Check your model's manual before proceeding.

Before you try the solution

  1. 1. Copy the complete message exactly as shown, including any letters, spaces, or punctuation around 2-sided Disabled.
  2. 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
  3. 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.

Manufacturer-documented solution
