Dişli şarj olmuyor

@Mom2Lu, Welcome to HP Support Community!
 
I see that you’re unable to charge the printer or power it on. Try the steps below and see if that makes a difference-
 
Use a different USB cable to charge the device. Also, try resetting the printer.
 

Turn on the Sprocket.

Remove the Paper Cover, and then use a narrow object, such as a pen or paperclip, to press and hold the Reset button for 3 seconds until the Sprocket turns off.
NOTE: 
The location of the Reset button varies by Sprocket model. Typically, the button is located underneath the Paper Cover, but can also be found on the outside next to the charging port.

Example of resetting the HP Sprocket Select Photo Printer

Turn on the Sprocket.

Keep me posted.
