That's way less than I do mine for - 180/180. Usually, blacks turning brown are due to overheating.

If they've always been ok with those temps and times, and your setup hasn't changed, then maybe your press has developed a fault and is recording the wrong temperature.

What mug press are you using? Which inks? As webtrekker states, 180/180 is best starting point but Ricoh based SG inks cook for slightly less time, around 160.

Brown 'usually' indicates over cooking but I'd check all of your settings through.
