    Did you put the rear end cover back on the PCDU assembly and if so is the copper bias connector there and making contact?
    At least 50% of IT is a solution looking for a problem.

      Is it print quality or only copies, if so clean optics. Did you do Sp 3-701 for K dev. Was it a new dev unit, PM counter for PCU?

                Are you getting light copies on all colours or just one?

                  There is a TSB for this machine with this problem. Clean toner supply tube and if that doesn't work replace toner pump.

                    i agree these pumps are "almost" the same"clutch a bit beefier" as the mpc2800/mpc3501 pumps and i have changed a few with fairly low meters.
                    I usually check the Vt reading and if its high it is under toned,as i recall it needs to be around 2.50.

                        I doubt that has anything to do with it.
                        As others have suggested, it's probably a toner supply problem This is from the MP C4000, but I'm sure it applies here too:
                        SC 362 TD error Cyan (VT high) - TD sensor defective.
                        SC 362 TD error Cyan (VT high) - PCU defective.
                        SC 362 TD error Cyan (VT high) - check harness and connections
                        SC 362 TD error Cyan (VT high) - check hose pump and clutch

                        Just curious..... are the K, Y and C, M pumps interchangeable as in past models?

                          We use to interchange the color pump units before but not the hose. Hose comes in different length
                          Aye! Cut the crap

                            It is best if you replace the pump and hose as a set. If you order from Ricoh using the current part numbers, the pumps will come with the correct length hose for the color ordered.

                              Agree with that. Replacing them with new ones gives best results.
