I recently purchased an Epson ET 4700 printer and I have encountered an issue with the red light flashing. After doing some research, I found out that I may need to use the Adjustment Program to fix this problem. However, I am not familiar with how to use this program. Can anyone provide me with guidance on how to use the Adjustment Program for the Epson ET 4700 printer to resolve this issue? Any help would be greatly appreciated.
