*1 The laser classification for FDA (CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice No.50.
*2 The only TrueType and OpenType fonts supported are those fonts whose "Font embeddability" property is set to "Installable" or "Editable." This property can be viewed from the Properties dialogue boxes of the fonts shown on the [Fonts] screen in [Control Panel] .
*3 There are two USB ports : a Type A connector for connecting USB memory devices or a USB mouse and a Type B connector that is the dedicated port for Marking Builder 3 (ActiveX) . The Ethernet port supports communication with Marking Builder 3 (ActiveX) , TCP/IP communication, EtherNet/IP™ and PROFINET.
