I am working. I still had to run the activation program, which this time worked. Thank you for your assistance.

So, I have uploaded the attached firmware to the printer without issue. The printer shows the firmware version as 30.74.CM27J5. After restarting the printer, I still have a cartridge error. Maintenance Error - Cannot recognize Ink Cartridge. Try installing again. Suggestions? Currently, I have color ink that this a non-Epson ink, the other inks are Epson 802XL.

Firmware update went without issue. Firmware is at CM27KB. When I run the activation program (version 1.0.0.1) which has a bunch of interface issues, and I click Generate a error appears: Wrong ID code. I have the printer connected via USB, I have run the program as an administrator as well as a regular user. What do need to do to activate?
