Our FC7000MK2-75 is not responding to poll size, or the send command suddenly. This development came after a pretty violent thunderstorm one evening late. The unit was left on overnight but the PC that it is connected to via USB cable and protected by an APC brand UPS unit was off. Tried several different cables and even other PC's but no communication between cutter and PC at all. Roland suggested that we try a parallel connection to see if we can bypass the communication problem so we have ordered a cable from them. They also say that this is a common problem but this is the first time I have ever run into this situation. So, I am wondering if any of you have ever experienced this before and did you switch to a parallel cable?
