スプロケット2in1が赤く点滅

@Mvancini
Thank you for posting on HP Support Community.
 
Don’t worry as I’ll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  
reset the Sprocket with a straight pin to clear any errors.

Turn on the Sprocket.

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

Slide the paper cover

Remove the paper cover

Locate the reset button.

Gently insert a straight pin into the reset button access point, and then press the reset button for 3 seconds.
The Sprocket resets and turns off.

Turn on the Sprocket.

Also, upgrade the sprocket firmware if the issue persists:
Upgrade the Sprocket firmware using the HP sprocket app. HP regularly releases firmware updates.

Make sure the Sprocket is charged 50% or more.

Make sure the Sprocket 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 the sprocket .

Tap Printers , and then tap your sprocket in the list.
The Sprocket 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 Sprocket firmware is up-to-date.
