I have an IBM 4029 laser printer that constantly jams. I opened the cover
to look around inside and immediately saw the problem. In the back right
corner was a broken blue piece of plastic where a spring had attached to
it. I later learned this is the registration roller. A local dealer
ordered me the replacement parts and said I should be able to replace them.
I'm very mechanical however all this brittle plastic and no obvious means
of disassembly scares me somewhat. Is there a service manual available or
can someone out there help me with a step by step guide on replacing these
parts? Maybe this isn't a do it yourself type thing.
