NOTE: All appears good with parts as far as what I can see without taking the side panel off. Nothing looks damaged, and it doesn't matter what order I start putting ink in. 2 upper and shows ink levels, then error with 3rd or 4th or I can reset and start loading 2 lower, 1 and 3, 2 and 4...and sometimes a third, but eventually a click sound when closing the door from loading final cartridge(s) and when I shut the mechanism appears to not work (ink covers opening and closing as shutting or opening door) then getting error message again. Guess that is all I have. Hopefully this can help others troubleshoot, but only good if someone has solution. Any questions or further troubleshooting I need to do please let me know.
Thanks,
Shawn
