    SC 142 (MP 7001)

    The original problem of the machine is light copy. So I replaced the complete drum set. After three weeks, the client called again and he complained the same problem. I told him the machine requires developer and TD sensor. He did not use the machine since then. Today, I went back and replaced those materials I requested for the machine. When I switch on the machine, it shows SC 142. The copy lamp did not lit up. I was surprised! I just changed the developer and TD sensor. Have you encountered this kind of problem?
