Uncertified Voting Equiptment?

What is really bugging me now that I am digging into it is the phrase: "...except for those from the city of Hartford, where voters still push a lever to select a candidate and a machine tallies the votes." from this article in the Washington / Ozaukee section of the Milwaukee Journal-Sentinel.

WI state statute 5.91(18) clearly states no voting machine can be certified if it does not produce a piece of paper. Chapter 5.91 sets the minimum standards for certification of ballots and machines used in Wisconsin.

How this piece of uncertifable equipment even in use?

Is this the WI State Election Board and Kevin Kennedy asleep at the switch?
