Hi @YU363 

Welcome to the HP support community.

I understand you're experiencing an issue with your HP device, and I apologize for any inconvenience this may have caused. I'm here to help you today.

Lines down the page can be caused by a few things - depending on what the line looks like.

If it is a smudged dirty streaky mark continously down the page, you migh have a dirty fuser - it may have been picking up toner and it has built up and then put it back down on the paper.

A thin defined black line might be a scratched drum or developer - the laser might be refracting and drawing the defect onto the drum.

Blank or white lines could be something stopping the toner from getting to the paper - transfer roller under the toner might have something stuck on it.

A repeated mark or defect could also be a dirty fuser - glue or wax from envelopes and labels could do this.

Try swapping the toner with another to test - borrow one if you can.

Run 3 or 4 cleaning pages - in the menu, configure device, print quality menu, create/process cleaning page.

For cleaning refer to this document :

Refer to this docuement for issue with print quality:
