John_Admin 389 Report post Posted March 5, 2020 Yes Printer must be connected to PC You can't use License.exe utility if printer is not connected to PC Share this post Link to post Share on other sites
Sacha 0 Report post Posted March 5, 2020 I did the steps. It was updating the software and at 99 percent it stopped and gave error message of either the usb cable is not connected or printer is not on which was not the care. The printer turned off and back on at around 70 percent. The ink icon shows a yellow explanation point Any suggestions? I didn't take out ink. Sacha Share this post Link to post Share on other sites
