White line above HP sprocket photos

HP Recommended
HP Sprocket

There's always a white "line" at the top of the hp sprocket photos when I print them out. It all started a while ago and I don't know what the problem is. Help please?

Clean the Sprocket paper path rollers


Dirt and debris on the paper path rollers can cause print quality issues. Use the colored Print Quality Card (formerly the Smartsheet) from the same pack of HP ZINK photo paper currently in the Sprocket to clean the paper path rollers.


To avoid print quality issues, do not use a colored card from a different pack of photo paper.

  1. Remove the Paper Cover, and then remove any photo paper from the input tray.

  2. Roll the paper path rollers back and forth several times.

  3. Check the photo paper and remove any severely bent, wrinkled, or torn photo paper from the stack.

  4. Reload the photo paper with the colored card on the bottom of the stack with the barcode facing down.

  5. Replace the Paper Cover, and then send a print job.

Refer to this document: for Improving Print Quality.
