I can see some steam or moisture from the vents when printing.
The moisture content of paper will vary depending on how it is stored. During printing, the paper is heated rapidly and warm, moist air will rise from the paper. When it encounters cooler air, water vapour or steam is produced. This is normal behaviour and should not cause concern, the vapour will quickly dissipate and print quality will not be affected. You can minimise this occurrence by ensuring the machine is in a well-ventilated area, and paper is stored in a low humidity environment.
