Deane Smalley, Danny Whitaker's penalty and Jack Lester put the hosts into a commanding position, while Craig Davies added a fourth after Jon-Paul Pittman's consolation for the visitors.
Sheridan said: "It was a big game, but there's still a long way to go and nothing is settled one way or the other.
"After losing on Saturday (2-0 at home to Morecambe) there was a lot of hurt in the club and we reacted in the best possible way.
"There's still a lot to play for, but this was a game we needed to win after letting ourselves down on Saturday.
"That was one of our worst performances since I've been here, but this one would have to be ranked up there with the best."
