Brother 2040 Toner Light Stuck

 After changing a toner cartridge and drum, a user’s printer would no longer print, and the Toner light was staying on.  The following procedure fixed it.

  1. Turn the unit off.
  2. Open the front cover.
  3. Hold the Go button while turning the unit back on.
  4. When all the LEDs come on, release Go, then press Go twice.
  5. When all the LEDs come on a 2nd time, press Go 5 times.
  6. Once the Ready light comes on, close the front cover.
