I'm sure this has been done already but let's see.
What is your best/wierdest/craziest/etc...etc...etc field engineering fix you've done?? I'll start:
On an old Ricoh 5570 the fuser drive shaft transmitted drive from the main motor to the upper fusing roller. This shaft had a bearing on each end of a small metal frame and these bearings would sieze up, eating through the drive shaft and would put the machine down if you didn't have the parts on hand. In a hospital this occurred and the old "we've gotta have it NOW" sob story was given. I removed the shaft from the unit. I found a paper clip and straightened it then wrapped it counter to the rotation of the shaft in the worn area that once held the bearing. I freed the bearings up, lubed them graciously, then reassembled the machine. It ran 3 days before I returned without fail. I replaced the shaft but kept it just in case.......
Not major, but I was proud
