I found User Manuals
but no drivers on the manufacturers website: http://www.samsung.com/sg/support/se...Word=SCX3185FW
but you can download the driver from this web site: http://www.siliconguide.com/drivers/device/1371/
Note: When you click the download link, it takes about 30 seconds for the download to start. Your download time may vary depending on your location.
