Have an HP 1220 c that is a good and faithful printer for my need. It
will only pass the thinist of photo papers now. Have tried sanding
the rubber gripper/paper advance wheels with only very temporary
success. Any suggestions on a better fix would be appreciated.

Bill-

There is a product for use on automobile tires and plastic dashboards,
called Armor All (http://www.armorall.com/). Used on your printer
rollers, I understand it replaces the plasticizer chemical that has been
absorbed by printer paper, so they will again grab the paper.
