A bill telling election officials to use paper ballots this year instead of electronic voting machines is starting through the Legislature.
A state Senate committee has scheduled a hearing on the measure for later Monday.
Secretary of State Mike Coffman decertified most of the state's electronic voting and ballot-counting machines in December because of security and accuracy concerns.
Many have since been cleared for use, with restrictions.
Legislative leaders and the governor have endorsed using paper ballots this year while the voting machine problems are sorted out.
But some counties have switched entirely to computerized voting machines and say they don't have enough scanners to count all the paper ballots that would be cast.
