My Ricoh CL7000 keeps asking to replace the yellow toner, which I have done and it goes through the motions of loading the toner then the error message comes back again - asking to replace the yellow...
The toner cartridges for the CL7000 have microchips embedded in them, so the machine knows if it's not a new cartridge. Was the cartridge you put in brand new? (And was it a genuine Ricoh cartridge?)
On those printers, the toner is pumped into a developer system and mixed with the developer before making the image. In the developer unit, the density is checked, so if it's not seeing the right mix there, one of three common problems could be causing this.
The more likely solution is to replace the yellow developer unit, which comes as a whole unit and just slides right in. That will reset your density levels and should correct the "load toner" error.
There is a spring and cushion mechanism that the toner cartridge sits on -- this mechanism can easily be popped out of place and cause problems loading the toner. Take out the yellow toner as well as one of the other colors, and see if the little black circular piece is sitting the same way for both colors. If not, just pop it back into place, using the second color as a guide.
The other likely possibility is that the yellow toner supply tube is clogged, but that doesn't happen very often. To test if it's clogged, take out the yellow toner cartridge and the yellow developer unit and turn the copier off. Use a vacuum to provide suction at one end of the tube (the toner end will be easier) and put your finger on the other end (the developer end) and see if you feel the vacuum's suction. If not, there is probably a clog somewhere in the line.
If there is no clog and you can feel the suction, you may have a bad toner supply motor.
As a side note, if you find the problem and fix it, you might still have to put a new yellow toner cartridge in to get the machine running because it will think the cartridge you already tried is empty.
Hope that helps!
