How can I fix vertical banding on laser printer printouts?
My Ricoh Aficio SP C210SF multifunction printer (color laser) prints with vertical banding or drop-out in the same vertical column-like position on every page, as if the black toner needs replacing, but it was replaced 2 months ago. I've followed the troubleshooting tips in the User's Guide with no success. Those tips also suggest changing the UPC belt but we replaced that only 700 pages ago.
