Fighting Italian Dario Vangeli in his light welterweight opener, Maxwell was on the front foot throughout and landed two good shots at the end of round two.
The pair clash again the third and after an accidental collision of heads, the contest was stopped with Maxwell adjudged by the referee to have infringed and disqualified.
Maxwell's exit leaves just fellow Brit and Commonwealth silver medallist Josh Taylor, who won his opening bout earlier in the day, left in the light welterweight draw.
