To repair the Hp-9x Topcat idler gear, Isabelle suggests the following:
- Select a metal gear instead of cheap plastic.
- Drill the center axis to d=2,30-2,40mm.
- Insert on axis and push.
- Mount back printer on Topcat.
Isabelle's tip: you can order the metal gears described here from GHW Modellbauversand at:
www.modellbauershop.de

You'll have to drill it anyway though...
