Mission Viejo-based Auxilio Inc., a managed print services company focused on the healthcare industry, said it has signed a five-year, $18 million contract with the largest operating region of what it called “a top 10 U.S. health system.”

Auxilio did not disclose the system’s name. The company said that the contract starts Feb. 2 and extends the terms of two of its existing contracts with the system’s hospital network.

The company says that it serves more than 120 hospitals and manages over 1.3 billion documents annually.
