Try updating the Sprocket Firmware

Make sure the printer is charged 50% or more.

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

On your mobile device, open the HP sprocket app.

Tap the Menu icon , and then tap sprocket.

Tap Printers, and then tap your printer in the list.
The printer information screen displays.

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 printer firmware is up-to-date.

Also ensure the HP Sprocket Paper and Blue Smartsheet is loaded properly
 

Turn off the printer.

Remove the top cover by sliding it away from the output slot, and then set it aside.

Remove any loose photo paper from the input tray.

Reload the HP Sprocket Photo Paper with the blue Smartsheet®. Make sure the blue Smartsheet® is on the bottom of the stack with the bar-code facing down, and the HP Sprocket Photo Paper with the HP logos facing down.

   NOTE:Keep the Smartsheet® until you are done with all 10 sheets, and then discard it.

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.

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

If the issue persists, let’s 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.
