Replace the dev. unit blk as already suggested.
I had the same problem on an mpc2003 months ago, leaving out, as has been said, and I confirm, that they do not have a deep black of their own, it was too gray there, I replaced the development unit bk, however you do this:
clean the 3 id sensors, clean laser glasses
tap under the development assembly with the screwdriver handle, turn the magnetic roller gear back and forth with your hand, a dozen times, (this help to remove eventualy residue of poweder from doctor blade) and try, if it doesn't satisfy, replace it the dev unit, update the firmware, and only then do the process control (sp 3)

Sorry for the delay. We're still testing, but so far it seems to be the laser unit.
Will keep you posted. Cheers!

Sorry for the delay, I just found out I never gave closure to this thread.
It was indeed the laser unit.
Thank you all for your support.

I think these budget series will, like it's predecessors, always run with a noticeable lighter densitiy compared to IMC3000 and other higher models.
All you can do is keeping the ID sensor and laser clean and replace units if they have exceeded the PM yield and run a paper with a very smooth surface. "Color Copy" paper will improve the quality a lot. Even with new PCDUs you'll notice a certain density degradation after a short period of time - seems the process control has it's own mind.
Things usually got worse in low volume enviroments - if the PCDUs are within yield you can run some force toner cycles and check the density in between. Don't overdo it... If the print looks ok -> re initialize the developers and you are sort of "good to go" for some time.
Lately I've been opting for tweaking the "procon target" to increase toner density when customer complains it's too low - raise by 0.01 or 0.02 and then let it run for a while to see how it goes. I've even had one customer say it was too dense - hence I reduced procon target by -0.02 and she was happy.
