Hello...We are primarily Konica Minolta repair but have a client that has a few legacy Ricoh MP C2003. Having an issuing with the yellow overtoning all all prints/copies. We've replaced the drum and dev and reset the voltage in the SP2-005-238 to what is specified on the drum. We've done a color calibration and have looked in the service manual but no luck..any suggestions? Thanks!

Re: C2003 overtoning
Did you set SP 3701-071 to 1 before replacing the Y drum and SP 3701-072 to 1 before replacing the Y development unit? If not, the value entered in SP 2005-238 most likely did not get loaded to the engine. Do so now, reenter the value from the PCU sticker into SP2-005-238 and cycle the power off and back on. That number is a correction number for the toner density sensor. SP 3701 also resets the PM counters for you.Comment

Re: C2003 overtoning
To avoid damage and above all not to make a bad impression with the customer, next time I suggest you ask for suggestions before getting your hands on these machines, good luck.Comment

Re: C2003 overtoning
there is a sheet inside a pcu box, that explain all procedure and system SP to perfect install part, do not reset both parts at the same time, first reset one, then restart, and reset the other, and restart the machine, then check the reset in the pm counters, replacing those developer unit + pcu, you will solve that problem .... ah ... clean the sensors id and do the calibration from user tools at the end"loneliness is an invention of the white man, when we are alone we talk to everything around us, we are never alone" (Ojibwa)Comment

Re: C2003 overtoning
If you reset both in same time, happen that if you go to check, you will notice that the pm of the developer unit is reset, the pcu no, regarding the calibration, I think that the value to be entered is a only "fine adjustment".
Anyway, i do a complete calibration at the end of maintenance,"loneliness is an invention of the white man, when we are alone we talk to everything around us, we are never alone" (Ojibwa)Comment

Re: C2003 overtoning
On model with more costous developer unit, like 3003, you can replace only the developer powder, i put It the MPC 2500 developer powder in the my mpc6003 dveloper unit, with overtoner, and work great, but i must add a bit of old powder mix because the MPC 2500 box have minor quantity"loneliness is an invention of the white man, when we are alone we talk to everything around us, we are never alone" (Ojibwa)Comment
