If the paper is loaded with a micro-SD card with available storage – Captures a photo using the camera, a shutter sound plays, saves a digital version to micro-SD card, and one copy of the photo prints
If no paper is loaded with a micro-SD card with available storage – Captures a photo using the camera, an error sound plays, and saves a digital version to the micro-SD card (Micro-SD Storage LED blinks red)

Installing a Micro-SD card -
 
1) Make sure your HP Sprocket 2-in-1 is powered OFF. Use a fingernail to insert a micro-SD card into your device. The label on the micro-SD card should be facing up towards the Paper Cover.
2) The Micro-SD Storage LED will turn red if there is a card error. Remove the micro-SD card, restart the printer, and then reinsert the micro-SD card to clear the error.
3) When a micro-SD card is inserted in the device and the device is connected to a computer using the USB Charging Cable, instant camera and printer functionality is unavailable. 

Hope this helps!
 
Let me know how that goes.
