Query: Nice shape, but with a lot of BLACK and SILVER IRON POWDER

This machine can give you a very nice shaped pasta if you prepare the dough with bread machine. However, it will also return you a pasta sheet with a lot of BLACK, SILVER IRON POWDER. Inititally, I though it is a normal manufacturing problem, and it could be cleaned by passing the dough for several times. Unfortunately, I repeated this process for over two hours (more than 50 times), it still returned me the same thing and with the same amount of IRON POWDER. I don't recommend this machine unless you know how to clean it entirly.
