Hello,
I suggest you have a read on the Airbus Safety First #15 from February 2015. You google it and can download for free. There is an article about Smokes Procedures.
From what I understand: After troubleshooting if no more perceptible smoke within 5 minutes, you can reset the ventilation blower, extract and cabin fans. These were reconfigured to prevent smoke recirculation and for crew protection. If smoke disappears then you should set them back to normal.
Edit: If you go on “Win Airbus” they also have made a couple of videos on how to deal with smokes.
