Same problem. Sprocket printing with lines, surface not smooth

[anabanana23]

Hello. I have a problem when printing with my sprocket. The print is full of lines. While printing it makes a wierd "tap tap tap" sound, and then the surface of the picture is not smooth. I saw many had this problem. I tried the solutions posted, updated the firmware, uninstalled the app, etc. It worked for 1 print, but the next day the problem persisted.

Welcome to the HP support community.

I understand that you are getting print quality issues, I am glad to assist you.

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 loaded in the Sprocket to clean the paper path rollers.

NOTE: 

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. 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 wait while the Sprocket detects and cleans the paper path rollers with the colored card.

   If the Sprocket does not automatically detect the colored card, send a print job to manually start the cleaning process.

Upgrade the Sprocket firmware

HP regularly releases firmware updates. Upgrading the firmware might resolve the issue.

1. Make sure the Sprocket is on and your mobile device is connected to the Internet.

2. On your mobile device, open the HP sprocket app.

3. Tap the Menu icon , and then tap sprocket.

4. Tap Manage Printers, make sure your Sprocket is selected, and then tap Printer Settings.

5. Under the Status section, locate Battery.

   • If the battery charge is 25% or higher, continue with these steps.

   • If the battery charge is 24% or lower, charge the battery for at least 30 minutes, and then continue with these steps.

6. In Printer Settings, look for a firmware upgrade.

   • If a firmware upgrade displays, tap Get Firmware Upgrade, and then follow the on-screen prompts to complete the update.

   • If a firmware upgrade option does not display, the firmware is up-to-date.
