Black Lines on the print out using Sprocket

HP Recommended

I am also experiencing the same problem. 😞 I already did what he did and will be trying to follow your (HP asst) advice. This will only be my 2nd pack of Zink paper and I can't understand if I have to replace my printer this soon. It hasn't been a year since I bought this. 😞

A warm welcome to HP forums! This is a great place to get support, find answers and tips to your technical queries.

Upgrading the printer firmware and cleaning the paper path rollers should improve the HP Sprocket print quality. Please try steps 3, 4 and 5 from this document. 

Let me know how it goes!
