Are you using OEM Toner??? I have discovered that non OEM Toner tends to shed off the drum and foul the ID sensor. And yes, alcohol can fog the acrylic lens of the sensor!!!

What I have encountered in the past is that the brush can cause dusting of the ID sensor when techs try to correct light print by forcing toner. This results in an over toned condition and toner dusting everywhere. At one time Ricoh had introduced a different brush to help correct a spotting problem with drums. Also helped with frequent dusting of the ID sensor.

And dont clean the drum mylar with anything but water.
if you use alcohol or windex it will dry it out and destroy it..
Is the coverage of black on a high level? Try checking the settings of SP 2209 (toner supply rate).
Check the reading on VSG and VSP. Vsg should be at 3.98 to 4 considering you are running on new drum. Vsp should be at 0.1 to 0.20 when the image is solid.
I had a similar machine.. I replaced the dv, dv unit, and the toner add sensor on the toner hopper. So far, so good.
I have several of these on a campus. I have also seen the toner hopper go bad. try turning the toner supply gear on the back of the toner hopper. if it is too stiff or squeaking it might enough to stop the toner clutch from working. Another quick way to tell is run forced toner once and see if the copy quality changes. If it doesn't it could be that toner hopper.
