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!
