I removed the lithium CMOS 3 volt battery, connected 2 wires at +(red) and - (black). Open a hole at plastic cover, and now I’m using 2 AA in serial, in a holder externally. To refill the cartridges , first open the cover till carriage stops in the middle. Second disconnect the 120 V power cable. Third remove the external CMOS 2 AA batteries, from the holder . Forth remove ink cartridges, refill and install them in the carriage. Insert exterior CMOS 2 AA batteries in the holder, Connect the power cable and you are good to go.

I removed all the board fasteners to be sure. That small metal hook down below your right thumb. Be careful there no to damage the board. 10 minutes and done!

Apparently the screws are T10 not T9. T9 works but you'll slightly damage the screw.
