free printer "needs some tlc" error code 1138 :)

1

in reciept of a free printer that “needs some tlc”…epson 7700. attempts to power on lead to error 1138…attempts to power on in serviceman mode are unsuccessful…holding down right, ok, down then hitting power, leads to same error message. previous owner used some pretty bootleg-looking carts, in general not sure when this was last used or powered on. any help would be much appreciated!
