Hello friends! I have a Ricoh 7502 and SR4060 finisher. I've been using without problem until now. But when service was comming, they told me that "would you like to update firmware of machine". I said "YES" ; it was my mistake. After he update firmware; my machine doesn't collate job separation. It is so important for me. When I want to take 2-3 copy of one file; no problem; it collates every parts. But for example; I have 10 different word files, when I want to take print them it puts top to top, it doesn't collate. I have to collate every paper by finger. I am near to crazy. Does it has any solution? I will pray for him.
