Can't be rid of it. Cleaned laser/diodes/slit/all mirrors/checked my wiring harnesses to ipu and replaced the ipu pcb. When I went back to replace the ipu I turned it on and it came to ready. I made 20 copies and it tripped the code again sc220 and now it wont go away. Ideas appreciated. Thanks t

Door Switches / Laser Synch Detector / Polygon Mirror Motor. I would put more weight on the first two, but not from having seen it in this engine family.
