USER'S GUIDE  Notes When you use the automatic emulation selection, note the following:  Once the emulation is automatically changed, it is not changed again for a short period of time. This time period is called "Time Out" and it can be set with the Emulation button. The factory setting is 5 seconds.  The EPSON or IBM emulation mode priority must be selected, as the printer cannot distinguish between them. Since the factory setting is the EPSON emulation mode, you might need to select the IBM emulation mode with the Emulation button when you need to use this emulation..  Try this function with your application software or network server. If the function does not work properly, select the required emulation mode manually using the printer panel buttons or use emulation selection commands from your software. 3-2
