Sprocket 200 电源按钮不会关闭

Hi @13KatieB
Welcome to the HP Support Community. I’d be happy to assist you. Let us try these steps to resolve this issue:
 
Hardware Reset

Make sure the printer is on.

Remove the paper cover.

Locate the Reset button.

With a paperclip or pin, press and hold the Reset button until the Charging Indicator light turns off.
The printer resets and turns off.

Replace the paper cover, and then turn on the printer.

 Upgrade the Sprocket firmware

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 sprocket.

Tap Manage Printers, make sure your Sprocket is selected, and then tap Printer Settings.

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.

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.
