If this reset fails, it would indicate an internal failure (faulty eeprom, meaning a bad logic/control board).
As this is a 2009 model printer, it is well past its designed maximum 5 year service life. The printer would need to be replaced at this point.
While it can be fixed, it is not worthwhile to do so. You would be looking at $200-250 in repair costs. For the same price you can replace the entire machine with a brand new model, with current technology and a fresh warranty, which makes more sense than buying the new part for an older printer.
Depending how you'd like to proceed, I can help with finding parts, finding a local repair shop, or recommending replacement options for you. Just let me know.
