Epson F2100 - Why does my print suddenly stop working and the power and the print buttons start blinking blue?

 If you are getting that error, it very likely has to do with one of these situations below:
  • Computer cable connection issue. Replace the USB cable.
  • The computer is going into sleep mode or the cable connection is bad. Switch out the USB slot and make sure to remove sleep mode.
  • Another program is trying to access your printer while you are sending jobs. See if there is any other program running on your computer.
  • You are not sending F2100 print files to the Garment Creator program. Go to option -> Configuration and make sure the printer "F2100" is selected not F2000.
