Thank you for joining HP Forums. 

I'll be glad to help you 🙂 

As I understand the printer is missing complete and/or half lines while printing,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you check if the issue persists, while using the copier as a stand alone?

Does the ink smear on the back of the printouts?

While you respond to that, here's a few things you need to do:

Step 1: Use genuine HP ink cartridges

HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. If you do not use genuine HP cartridges, the steps in this document might not resolve the issue. To check the authenticity of your cartridges, go to hp.com/go/anticounterfeit.

Step 2: Check for ink smears on the back of printouts

If there are smears of ink on the back of your printouts, you can use an automated tool to resolve the issue.

Step 3: Make sure you are using the appropriate paper for your print job

Using incorrect paper for the print job might cause warping, lines, or streaks. Refer to the following guidelines to make sure the paper you are using is appropriate. If it is not, reload the printer with an appropriate paper type.
