A white line on the edge

[DWong818]

I have experienced with the white line printed all over the photos. 

Product Name: HP Sprocket 

Mobile: Huawei P20 Pro

Operating System: Android 9.0

I have tried reinstall the application, reset the sprocket but the issues still exist. 

Please help.

Welcome to the HP Support Community.

HP regularly releases firmware updates. Upgrading the firmware might resolve the issue.

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

2. On your mobile device, open the HP sprocket app.

3. Tap the Menu icon , and then tap sprocket.

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

5. 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.

6. 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.
