Phil, even though they look ok, blow each one out with a blowgun, if you 
don't already know about www.printerworks.com, they have a breakdown of 
each model, makes it easy to ensure you don't miss a flippy lever or 
two. Every phantom jam I've ever had eventually turned out to be a dusty 
optoisolator. Finding which damn one is the hard part.
