I have a Xerox 700 077-113 fault code on a machine I just bought. Can anyone tell me where the IOT Final Exit Sensor is located? Paper is printing and making it out half way into the Interface Module and stops before the first rollers can pick up the paper and gives me a jam message. Fault code (077-113) when I look it up says "IOT Exit Sensor OFF Jam (Non Invert) - In Non-Invert Mode, IOT Exit Sensor is not turned OFF within a spec time." Please help...need to get this machine running ASAP! Thanks in advance!
