HP LaserJet MFP M140we Printer

I am struggling to print anything with the printer since purchasing a new toner. Please could someone help me? 

 

From what I found online, it is due to the new cartridge:

The HP LaserJet MFP M140we printer, which is part of the HP+ series, has been known to display an “ER 75” error message after installing a new store-bought HP 141A toner cartridge. This issue often occurs when transitioning from an HP Ink subscription to using store-bought toner cartridges. 

 

Can someone help me? Thank you!!
