Printer certificate error message in HP Smart Android app

HP Recommended

I can't scan as via the Android app it is informing me that there is a new printer certificate but it will now acknowledge I am accepting it.  I can print but I can't scan.

Hi   @BruinsSF 


Please try below steps for 'change of printer certification' issue:


Steps to resolve the issue:


  1. Clear HP Smart app Data from Android Mobile device. Go to Mobile Phone Setting -> Apps -> HP Smart –> Storage –> Clear Data
  2. Power Off the printer, wait for 1 minute, power on the printer, wait until the printer is connected to the wireless network (lightbar is steady on)
  3. Launch HP Smart app, add the printer by tapping ‘+’   


What will happen in HP Smart app after ‘Clear data’

  • User will run through all the dialogs again like a fresh HP Smart app installation.
  • User needs to add all printers to HP Smart app again by tapping ‘+’
  • Tiles shown in home page will become default.  User has to personalize tiles again.
  • HPID and Cloud accounts are signed out. User needs to login again.
  • This does not affect Smart Tasks, Mobile Fax which are part of cloud service.


Please let me know if that helps.
