Is the temperature of the room too low?
Use the machine in an environment where the temperature is 20°C to 28°C (68°F to 82.4°F).
The media heating system may not warm up sufficiently when the ambient temperature is less than 20°C (68°F). Also, even when the media heating system reaches its set temperatures, adequate effectiveness may not be apparent if the media is thoroughly chilled. Before printing, allow the media to come to room temperature.
