what application are you printing from? also, can you do a print preview to see if there are more than one page? if that works, then your printer mechanism is not following the driver information from the print queue manager.
1. Check that you are using the latest print driver - from kyocera website.
2. If the issue is when you print pdf files then make sure you set the printer in KPDL Auto mode - check the print driver settings about this and the printer menu.
3.You may check if you have the latest firmware installed within the printer - print a service status page (Menu->Others->Service).
