Th e order was delivered promptly, was neatly packed and I immediately got down to the exchange. The printhead was easy inserting. As a precaution, he was filled by me even with a complete set of new cartridges. The previous message the old head was gone, the print head has been recognized properly. After several cleaning cycles, so that ink reaches the bottom - the first pressure test - Immaculate printing, without an error message, but no ink on the paper! : -O Do not know how many attempts - cleaning, removal and installation, paper check, declarations from the Internet, - to this day not a drop of ink on the paper - I resigned and write the 80 from. If only I had the same successor under 80 ordered.! Do not know, it's up to the head or to the printer, I can not help but -einsetzen him ????
