Yep. Just did upper and lower feed rollers and transfer pads on my LJIIID.
Ran about $30 in parts and a lot of labor/time (I haven't been inside a
printer in several years and I had several false starts).

Nice description about how to get to the upper roller. I wish there were an
easy way to get to the lower transfer pad. I just about stripped the printer
bare to do it (on the bright side, I did learn what goes where and what has
to come off (and go back on!) first).

Commonly called "circlips" on this end of the pond.

I ran into one problem - some of those other components were worn enough
that I accidentally put the D-shaped roller 180 degrees around. Yes, it's
possible. No, it's not supposed to be possible. There is a small pin that
is supposed to fit into one of the hard rollers next to the rubber rollers,
but it moved around too much during disassembly and I got it wrong the first
time. It caused a jam on pickup because the flat spot on the D wasn't down
when the next stage went to grab the paper and it stopped dead.

That's where I got mine. About $8 each.

Even though the printer was $15 to me (complete with two paper trays,
LocalTalk card, 4Mb memory card and Postscript cart), it was worth it
to drop another 200% to get it working. It's slow, but works like a
champ now. The only thing I haven't tested is double-sided printing.

Does anyone out there have a 10BaseT card they can't use? I'd rather
throw this thing on the network than waste my only print-server port
on it.

Thanks,
