--- UPDATE:
Eight months after the purchase of the printer failed each service: The level indicators of three cartridges were flashing, whereby the printer will indicate that they are to replace. Despite the replacement by original Canon cartridges, it was no longer possible to print. The Canon service erwiest located here as unable to solve the problem.
I was not alone with this problem, showed a quick Google search with countless forums entries. Debt was the chip technology of the cartridges (each cartridge has a chip, which is designed to prevent the substitution of third-party cartridges)
Amazon appeared as usual customer friendly and took the equipment back under the refund of the full purchase price.
My conclusion therefore: a Canon printer with "chip cartridges" I will not buy me.
