I bought a Samsung ML - 1665 laser printer last week, set it up and started to print. Immediately steam began issuing from the top as each sheet printed, while the sheets themselves were crinkled as if they'd been steamed. I phoned Samsung who told me that the steam is a film burning off an interior part and that it would be ok after 400 sheets! Well, I printed 350 approx and there was no sign of improvement, so I brought it back and got another one (same model), but it's the same. Have I just been unlucky, or do you have to 'run-in' a laser printer like a car from 1930?
