Product: HP LaserJet Pro MFP M428fdw

I am no longer able to print due to the "Expired Certificate" error.  (Out Of Warranty)

 

The printer doesn't retain date and time after I power it down and also doesn't retain the certificates when I update them.  

 

I used to be able to sync date and time and generate a new certificate which would work until I powered down the printer, but as of last month, it no longer works.  Even when I see a valid certificate and proper date and time, it is still giving me the error.

 

The printer is always plugged into power and has a good connection; firmware is up to date.

I have tried all of the other "solutions" to the wildly known issue that I have found on this website. 

 

Any thoughts other than going "Office Space" on this paperweight?
