HP-97 card reader, printer questions

[quantalume]

Just to be absolutely clear about things:

1. Duct tape is a generic term referring to tape formed by laminating polyethelene, cloth and a strong adhesive.
2. Duck tape is a trademarked brand of duct tape
3. The actual tape often used by HVAC professionals on ductwork is thin, adhesive-backed aluminum.
   

I do not think type #3 would be at all effective in repairing calculator printer feed rollers.

Katie, didn't you write up an exhaustive description of rebuilding a 97 printer somewhere?
