6/check maybe, I don't honestly remember every time I do it, neither do any of the other cashiers, or CSC or backups. We all hit random keys and do the / and hope for the best.
The official way to process these checks is like any other personal check, if necessary 5/ Check if problem running as a personal check. But policy is for ALL Checklane Checks to be processed though MICR reader (So the system can record and or decline depending on the account numbers)
