I have read past threads and i am stuck, don't usually work with Ricoh. Unit says add black toner, customer used compatible toner. Replaced black pump and tube. Installed OEM toner after pump replacement. Message continued. Swapped unit into another machine the customer had and both worked. Two days later the original machine came back with add toner message. The toner chip now reads empty. Toner unit turns. Cleaned sensor area behind toner hopper. Can hear pump working. Doesn't appear that toner is entering dv unit. Marked gears and dv unit is turning but I did notice that the black drive gear in the back of the machine can be turned easily by hand where the other color are hard to turn by hand. Turned sp5051 and sp3045 off and on. Any further advice before i pull the rest of my hair out.
Thanx
Brian
