We saw this a lot when the first Gigabyte NIC's came out. Most of our customers were still running 100MB network routers, and the MFP did not always accurately choose the correct network speed, especially on Konica Minoltas. Hard setting the network speed to 100MB solved this issue in several cases. Usually it would print one page, then stop communicating. If you re-booted the MFP you could have one more.
