K Dev bias board. Left hand side panel, small board towards the front of the machine

Test the black toner dispense motor and dispense pipe. When there is not enough supply of toner it will empty the developer.
Would you have a part number that I can give to Xerox please ?Originally Posted by jhalfhide

Thank you for your help.
I have ordered the board. Should be here in the next day or 2.
I have replaced the drum, both toners, and the developer housing and filled with fresh dev.
The dev housing was completely empty after 120 prints after filling the dev unit with dev .. no toner, no dev was in the dev unit when I took it out and had a look.
I replaced the black dispenser motor, but do not have any developer to test. I did run a 100 pages and no toner was delivered into the developer housing.
I did notice the Black Toner CRUM Read Board .. I'm not sure what this does and can't find anything online. Does this control the black dispenser motor at all ?
You can test the toner dispense motors from diagnostics Would be interesting to know if they work. The CRUM board just reads the chip from the toner

OMG .. it just keeps draining the developer housing of everything.
No toner is dropping into the dev unit at all, I am sure.
Have now replaced the K Dev bias board, the black dispnser motor, both black toner cartridges, the dev unit itself, the drum, and the ibt belt.
The shoot is clear, but did notice a little strip with a silver patch at the end of it coming out of the black shoot. None of the other Xerox machines I have worked upon has this acrylic strip with silver patch.
Any other suggestions please ?
The silver strip is suppose to be there. Have you tested the toner dispense motor from diagnostics? You can replace developer and bias boards all day long, but if it isn’t feeder toner it will keep emptying the developer housing.
After 375 pages it started to fade again indicating no toner, then at 470 SRA3 double sided pages it produced the toner dispenser error 093-317 and has a NVM of 3.
