Kyocera Ecosys FS-C5250DN

FS-C5250DN Unreliable Printing via LAN connection – Ive had this printer about 6 months now, and apart from this issue, its a great printer. I have this printer connected to our LAN and seding print jobs to it has been problematic since I got it. I have same issue printing fro 2 Windoze XP PCs and a MacBook running Mac OSX10.6 . USB printing is fine, works everytime, but often need to reboot printer 3 or more times to get it to print from the LAN again. IP address is static and Mapped in the TL-3420 router by MAC address. Wired or Wireless, it just randomly stops receiving print jobs. I cab access the Web pages on the printer fine, I can plug in a USB cable and print from there. Very Bad LAN printing problem!! Reasonably fast, good color prints for business use Un-reliable Printing via Ethernet Port
