Canon BJC4100

I bought a Canon BJC4100 for €250 more than 10 years ago. The print head was replaceable independently of the cartridges. Head +carts cost €45. Original carts cost €35, compatible ones cost €25. Refilling both carts cost €2.5.

Based on my (or rather my children's) usage and a new head every 18 months (pessimistic) I saved €250 annually by refilling the cartridges.

The printer was finally retired because it was literally wearing out mechanically and had become a little unreliable.

These are the kind of economics that make sense. I never felt screwed by Canon.
