My HP printer keeps flashing a blue light with error code B305DFF9.  The only thing I can do is unplug it, it will then work/print normally, but then starts flashing the blue light with error again.  I am at the latest driver firmware per HP website: (MANHHIPP1N002.2135A.00).  What other suggestions do you have to fix it?  Thanks!

Hi @SAS6,

 

I'd like to help!

 

I understand you are receiving a "B305" error on the printer screen.

 

We can perform a factory defaults on the printer to resolve the issue

 

 To restore the printer to the original factory defaults

 

1.From the printer control panel, touch or swipe down the tab at the top of the screen to open the Dashboard, and then touch ( Setup ).

2. Touch Printer Maintenance .

3. Touch Restore.

4. Touch Restore Factory Defaults. A message appears stating that the factory defaults will be restored.

 

Hope this helps! Keep me posted.
