Error Code 091-321

Product Name: VersaLink C405 Color Multifunction Printer
Operating System: Windows 10 x64

I replaced the full set of drum/imaging units in August. Now my printer won't print in black. I have changed the toner but this has made no difference. It's too expensive to purchase another new set of units just to check the black one. Anyone have any solutions
