Copying comes out blank

HP Recommended
Sprocket photo printer Z3Z91A

My sprocket printer has started to print out blank photos, instead of the photo i’m Trying to print. I’ve had my printer for 1 year, and it has worked totally fine, until a few weeks ago. I don’t know why it is printing blank photos, or what I can do about it. Maybe it needs new ink? I hope you will help me.

Thanks for reaching out to the HP Support community!


Let's try these steps:


Step 1: Use genuine HP ZINK photo paper


Step 2: Reset the Sprocket

  • Turn on the printer.
  • Locate the Reset button near the charging port.


  • Gently insert the straight pin into the reset button access point, and then press the Reset button for 3 seconds.
  • The printer resets and turns off.
  • Turn on the printer.
  • Reconnect the Sprocket via Bluetooth.

Step 3: Try Updating the Sprocket's Firmware

  • Make sure your Sprocket battery is charged greater than 75%
  • Ensure your Sprocket is powered on and connected to your phone via Bluetooth.
  • In the Sprocket mobile app, tap ‘menu’ (3 lines) -> ‘Sprocket’ -> ‘Printers’ -> ‘Get Firmware Upgrade’ 
  • Try printing a photo and check the quality.
