It looks like a Minolta 3102/2002. I believe the Konica models are 8020/8031 but I could be wrong on that, we were a Minolta dealer before the merger. What was the model number on it?
The finisher was sold as a Sharp AR-FN7 and as an Okidata finisher. I've also seen them attached to Panasonic MFPs. =^..^=
