Douglas Alward pleaded not guilty by reason of insanity to charges of escape, kidnapping and being a habitual criminal.
He will now undergo a sanity evaluation and will be back in court in December.
Alward escaped from the Sterling Correctional Facility in August 2010 after building a home-made ladder to scale a prison fence topped with razor wire.
He then used a shower curtain and cardboard to slide under the prison's electric fence without touching the wires.
The fence has since been changed.
After the incident, Alward told 9Wants to Know it was his seventh escape. We talked to him in a series of phone conversations and letters he sent since he escaped and was caught again.
Alward says he planned his seventh escape for two years, working nearly every day to gather materials to carry out his plot.
