I have been using Forte FB Polygrade and Polywarm for quite some time now with good success. The other day I opened up a new 100 sheet box of polygrade and it printed out with dramatically different results than the preceding box. This is the first time I have seen this. I have heard that forte has had these issues but I have never experienced it. For what its worth this box was purchased prior to their restructure and subsequent shortage of product in the market place. I am curious if others have run into issues like this with Forte. S.
