Hp sprocket is printing with white diagonal lines down the paper

[Samhat]

My hp sprocket is printing with white diagonal lines down the paper. I have updated the firmware but the problem is still happening. Has anyone got any suggestions.

Welcome to the HP Support Community.

Clean the Sprocket paper path rollers:

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

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

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

4. Replace the paper cover, and then send a print job.

   NOTE: 

   The Sprocket 200 automatically detects and prints the colored card when you replace the paper cover.

   The Sprocket calibrates and cleans the paper path rollers with the colored card, and then prints the photo.

If the issue persists, please perform the remaining steps from this document: https://support.hp.com/us-en/product/hp-sprocket-200-printer-series/21625473/document/c05660842
