After a chat with me Support a new print head has, for more than a week delivery time, sent. This brought the same mistake after just 10 pages. After another chat with me a new HP printer in exchange was promised. There but used incomplete printer without cables and without deflection was delivered. This was also Outward surface very worn (scratched). Allegedly is my only, despite guaranteed.
I am unwilling to accept this lack because I have given the manufacturer an opportunity to rework.
Amazon as a dealer was very accommodating and took back the unit.
