Firefighters were called to Aylesford Newsprint on Thursday night, after a crane on a paper machine caught alight.
Crews from Maidstone and Larkfield were called to the factory in Bellingham Way, Aylesford, at about 8.15pm, but when they arrived the fire was out.
A spokesman for Kent Fire and Rescue Service, said: “Crews just made sure the scene was safe and no other fires had broken out."
They left 15 minutes later.
