Refilling is low, refill is therefore to your wallet ... Unfortunately, this has rather out at the Nachfülltet here reversed. My printer began to lubricate and the sheets were also heavily sodden after a print. Have first thought that maybe it was because of contamination, but that was not the case. After I inserted another, almost empty cartridge, the printed image was better. (Except that the cartridge was empty flat) Made and established, lubricate the filled cartridges the equivalent test again, run out, and siffen ultimately the printer fully. Bin again switched to "normal" cartridges from the manufacturer. It all goes again wonderful. Unfortunately, the printer is unusable but by the whole of refilled cartridges rumgesiffe and I had to buy a new printer. Thus, the purse was charged again. Too bad, but now I know better.
