Hello @cjvan ,
Welcome to the HP Support Community!

 

This is very unusual that 2 printers show the same behavior almost at the same time.
Print a cleaning page and then start a calibration.
If the error is still present, then print a "supplies status page".

Maybe the black toner cartridges have been replaced?

 

You will find more information here: https://support.hp.com/us-en/product/hp-laserjet-pro-mfp-m148-m149-series/21996897/model/21996899/do...

 

Kind Regards
