How can I force my printer to print in black when it can't recognize 2 colour cartridges?

So I currently have this issue where my Epson WF-3620DWF can't find the blue and yellow cartridges. (They are official epson ones) and I have a full black cartridge in there. How do I force my printer to ONLY print in black and ignore the cartridge(s) not recognised error?

Step 1 Close any applications from which you print. Click the Windows Start button to open the Start menu, then click “Devices and Printers” in the right column.

Step 2 Click to select the color printer you want to configure to print in black and white. Right-click the selected color printer, then click “Printing Preferences” in the context menu.

Step 3 Click the “Color” tab in the Printing Preferences window and select the “Print in grayscale” option. Select the “High quality” setting in the drop-down list below the “Print in grayscale” option. Click the “Apply” button, then click “OK.”

Step 4 Close the "Devices and Printers" window. Open Microsoft Word or another program from which you want to print color documents in black and white. Open a file that contains a color image. Click “File” and “Print,” then click “OK” or “Print” in the Print dialog box.

There is also a trick to ignore the warning message:

Disabling the EPSON Status Monitor is the only way to stop annoying warning messages due to using third-party ink cartridges including the non-genuine ink warning message.
