@Sird, Welcome to the HP Support Community!

To assist you better, what model sprocket are you using?

Refer to this document to identify the model.

For now, let us try these steps:

1. Reload the HP Sprocket Photo Paper with the blue Print Quality Card (formerly Smartsheet). Make sure the blue card is on the bottom of the stack with the barcode facing down, and the HP Sprocket Photo Paper with the HP logos facing down.

   NOTE: 

   Keep the blue card until you are done with all 10 sheets, and then discard it.

   

2. Align the top cover with the tracks on the outside of the printer, and then slide the top cover toward the output slot until it is firmly seated.

   1. Align the top cover

   2. Slide the top cover

3. Turn on the printer, and then resend the print job.

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.

Send a print job. If the print quality is still unacceptable, continue to the next step.

Also, check for updates on your iPhone
