i had problems with the nozzles... i don't know if it was from the beginning... i made the mistake and only printed b/w in the beginning (because i only needed those... then after many months coloured and then yellow didn't work... started cleaning... then more nozzles spun... in the end i had to do the power cleaning (

so remember to print in colour when printing... i haven't had a problem since then
