Hello newmprint.dk
Please let me know how you arranged to have the Buffer Pass Unit installed Free. I am going through the same issues, with blocking/bricking plus skewed coated sheets when making books. It is a really bad problem. My own local service company does not even know what a Buffer Pass Unit is! I am shocked that these C5100s Pro's can be sold with so little knowledge of how they really work. Kind of leaves the operator in a lurch.
If there was a cost, does anyone know how much a Buffer Pass Unit is for a C5100s Pro? That is what I have.
They wanted to install a fan unit today, which they thought was the pass unit. I told them forget it, that isn't what I had asked for. Now we are back to the same problems. Very frustrating and very time consuming.
