Ohio Rev. Code § 2943.02: Arraignment.

An accused person shall be arraigned by the clerk of the court of common pleas, or his deputy, reading the indictment or information to the accused, unless the accused or his attorney waives the reading thereof. He shall then be asked to plead thereto. Arraignment shall be made immediately after the disposition of exceptions to the indictment, if any are filed, or, if no exceptions are filed, after reasonable opportunity has been given the accused to file such exceptions.
