an HP 9144 tape drive. He says that there's a hard roller inside the
tape cartridge, and there's a softer (rubber?) roller in the drive that
pushes against it, pulling the tape along. Apparently the softer rollers
tend to turn to "goo" after many years. He's been working to recover
some archived files from the beginnings of the company he works for,
mostly for historical interest, and his last tape drive recently
succumbed to the "goo" problem. Anyone have any replacement rollers that
would be in any better shape, or any suggestions for alternatives? Thanks!

OK, similar response for an HP 2761A optical mark reader? One issue here
is that I don't know the diameter of the original roller.

Perhaps someone has a service manual for this reader? Looks like Jeff
Moffatt had one for the interface card.
