... accordian at the registration roller, with no image on the paper and no latent developed image on the drum.
I've heard of these drum drive pins shearing, but only saw one for the first time today. The old piece is easy enough to press out of the shaft with vice grips. The hard part was matching the spring pin. It's 2.5mm x 15.5mm and uncommon enough that I don't have a single spare that size. But I do happen to have a #40 drill bit (0.098"), which happens to fit perfectly in the shaft and gear. My drill bit is now 15.5mm shorter.
