Sawyer's Rotomatic Vintage 500 retail watt Projector Model 700 w/ 2 Stack Loaders AS/IS

Product Name: Sawyer's Rotomatic Vintage 500 retail watt Projector Model 700 w/ 2 Stack Loaders AS/IS
Sawyer's Rotomatic Vintage 500 watt Projector Model 700 with 2 Stack Loaders - AS/IS Comes with 2 Stack Trays and The Fan and retail Lamp works. The focus seems to work when I use the remote, but when I try to turn the knob on the machine it works somewhat but clicks like the gear is stripped possibly. I can see small amounts of dust when pointed at a wall. Possibly needs taken apart and cleaned. Not sure if the timer switch functions as it should. I'm not familiar enough with this machine. When I push the cycle button on the remote the arm ejects out but doesn't return. Maybe normal. Overall it may function AS-IS otherwise should be repairable for someone that knows what they are doing. Sold AS-IS.
