I have worked on this model for years, and 9 times out of 10 "add toner" indicates a faulty toner pump. Put another one in and be sure and vacuum the supply tube. Also make sure the toner pump connector is seated, as it is difficult to get to (K pump).

The last time Ricoh updated most of the color machines, they went to different part numbers for each color toner pump. The new pumps include a new supply tube that is the correct length that color. Most of the time when I tried to vacuum the tube, it would clog again in a couple of months. Also, while the tube is disconnected from the nozzle, place a rag or piece of paper below the nozzle and rotate the bottle. If no toner comes out of the nozzle, replace the nozzle.

Have you tried turning off Toner end detect?
That will get rid of the replace toner message and show you if any other code is being hidden by that huge dumbassed message window.

Yep that fixed it.. THANKS SO MUCH !!! Really appreciate your feedback !!!

For me it has usually been the jam door on the paper bank. If the back end is out as little as 1/8 of an inch, it will be in a door open condition.

Yep that was it... The door was open on the right side.... After I turned off the toner send I saw it... Threw me for a HUGE loop.... Thanks so much for All your response !!!
