He became the printhead itself Ordered. At printer heart for almost 50 on a Sunday. The item has been delivered then already on Tuesday. The printhead was in a thin-walled plastic packaging not printed or designation. In the compared to the original print head I And arrived to the conclusion that there is indeed an original HP spare parts. All names and labels (numbers etc.) were in the same position as the original. An HP logo was also lasered. The installation fit, original printer cartridges which were the same as changed, fit well and were also recognized. However, the good piece printed then release not equal. However, this was not contrary to the printhead but more likely on the printer itself. Try After about 2 hours, and some trickery I have to bring the printer to make it run again. The printed image is clear without streaks.
But me sneaks but the stupid feeling that was not actually defective, the print head but said only an internal software that has the print head is defective to ring the cash register at HP. (Intentionally built error) Although the printer is already several years old but with not even 2000 pages and over feeding with original cartridges I think this is a rumor.
Product and Supplier printer heart I can finally say: TOP !!!
