PEKIN, Ill. (AP) — Officials in central Illinois say a printing glitch is responsible for some residents receiving up to eight voter registration cards recently.

Tazewell County Clerk John Ackerman tells The Peoria Journal Star that a printer froze and got multiple orders to reprint. That led to duplicate cards printed, some of which were mailed.

Ackerman apologizes for the inconvenience and “waste of resources.” A new printing process was expected to save around $6,000 this year, however after the glitch the savings was around $4,800.
