First technical post. Hope I am doing this right?????? New customer machine that local toner dealer put in a new pickup roller. They complained about multiple sheet feeding so went there and cleaned the machine. It worked fine until the next day. Ordered and replaced the tray sep pad. Worked for less than a day. First time working on one of these. Got the service manual. Wondering if anybody has experience on this problem before I tear into the machine. I see there is a Gear Pick Up and Solenoid, Feed Motor and or Feed Sensor that could be the problem. Thanks for any input!
