Disposal. We replaced the printer during the warranty, now the problem came back and I wasted 2 hours cleaning etc. which didn't help. We have now bought one of the cheapest HP printers for CHF 40 with the cheapest 805 cartridges. If it breaks down, we will simply replace the printer. It's actually quite blatant that a product with an "ECO tank" is branded as economical and ecological and then has to be disposed of.

Call up the printer service menu and run the printer test. tbc
