Because it was the only wy the settings could be changed. Judge just ignored the experts and chose the "Mistakes were made" excuse.
Well, no, that’s not what the judge said. The judge said that in the presence of problems, voters were given alternatives.
“The Court notes that Mr. Parikh also acknowledged a fact admitted by several of Plaintiff’s witnesses: that any ballot that could not be read due to BOD printer or tabulator failure could be submitted for ballot duplication and adjudication through Door 3 on the tabulators. Plaintiff’s own expert acknowledged that a ballot that was unable to be read at the vote center could be deposited by a voter, duplicated by a bipartisan board onto a readable ballot, and – in the final analysis – counted. Thus, Plaintiff’s expert on this point admitted that the voters who suffered from tabulator rejections would nevertheless have their votes counted. This, at a minimum, means that the actual impact element of Count II could not be proven. The BOD printer failures did not actually affect
the results of the election.” (page 6)
“It is worth repeating that ballots that could not be read by the tabulator immediately because of printer settings – or anything else – could be deposited in Door 3 of the tabulator and counted later after duplication by a bipartisan adjudication board.” (page 7)
