the translation is: usando/empleando pizarras blancas

or, if you mean 'whiteboards' (as in one word):

usando/empleando pizzaras

Translation: usando OR por usar

'You're busy using a translator' is one of many English equivalents of 'Stai usando un traduttore'. This is what you say to someone who's within your close circle of family, friends and peers. For someone outside that group or senior in age or rank, the phrase becomes '[Lei] sta usando un traduttore'.
