Had in the past many times ink Pelikan and never had problems with it. Was always the printer "accepted" and the print quality was maximum slightly below original cartridges level. It struck me that the (Pelican) cartridges, this time no longer blinking after I let them lock into the holder provided. (Yes, stands on top of the cartridge: "COPYRIGHT reasons" - what that means always). Anyway, I get now always the message Error 5700 - turn the printer off and back on, should not be the problem persists, look in the manual (which hand book ???) for further troubleshooting (or something similar). It may be that there has been a "regrettable" overlap of events. So that the printer has anyway now abandoned exactly his mind, even without cartridges Pelikan. But, sorry, just three minutes before everything was still fully functional. So: never again.
