Admin 17 Posted September 10, 2020 Solution: Step 1 Download and extract Zip archive with WF-C5790 Firmware: https://inkchip.net/download/INKCHIP.net_Firmware_99_WF5790_v1.rar Step 2 Delete all USB printers installed on your PC except that You want to make chipless. Reboot PC, restart printer. Step 3 Connect printer to PC (with Windows OS) by proper USB cable. Disable all Epson processes and services. Step 4 Upload Firmware to printer in the NORMAL MODE (do NOT use service mode yet just start the printer with the power button). Step 5 When Firmware Update process is complete - printer will restart - usually it will take only a few minutes but can continue for 10-20 minutes in some rare cases. If process hangs - replug power cable and start printer manually. Step 6 Now check current firmware version. If NO - restart the printer and try once more time. Step 7 Extract all files from License.zip archive to local folder on Your PC. Run activation.exe utility and click on Activate Online button and input Your Activation Key.

Puppy 0 Posted September 12, 2020 Hi Admin, Problem solved. My problem was that I fixed 3rd ink & installed the activation code. After fixed the original ink back to the machine and run with activation code. Then received installation successful. Then off the printer & fixed 3rd party ink and ON the machine. Thank you.
