There are two vertical areas that don't print black. Colors print fine.
Printer says toner cartridge is OK, and I did take the cartridge out and shake it.
Imager and fuser replaced relatively recently.
Test image below; note white areas at page's lower left (image is rotated, top of page is at left).
What's wrong with my printer?
