Vermeer 554 XL net wrap problems

I am considering buying a vermeer 554 xl silage special with net wrap, it has 11,000 bales on it, the dealer said they are selling it as is the net wrap doesn't work but it ties twine fine, they've tried the talcum powder on it and then it wraps sometimes.. any help or advicewould be appreciated, thanks
