Any suggestions?

I've had an MP6002 go light on me 60k after a developer unit and material replacement with 180k total on the machine and it ended up being my drum.
Otherwise, I have problems with Ricoh B/W's going light, just a matter of getting 50k, 100k or 200k before they do.
Drum has been replaced as well, using all OEM parts and supplies.
Replace the ID sensor. Someone in the past has cleaned if with alcohol which clouds the surface of the lens.
Try running SP3-001-002 ID sensor initialization. After that runs, check the ID sensor voltages. VSG should be 4.0V and VSP should be about 1/10 that (maybe 0.4V or close). These are SP3-003 1 & 2 respectively. If you see a 5.0V or 0V on any of those replace the ID sensor. If this machine is low volume try running SP2-962 forced process control. Then check copy quality and ID sensor again. Don't force tone the machine you will wind up with a mess. Let process control tone itself up. Also check drum conditions VL. SP3-902-008. This should be under +300. Make sure the developer unit filter is clean. If it clogs up pressure builds up in the dev unit and holds back toner during copying and that will not show low toner, just light copies.

What's worse; a waste of time or a waste of time and money? Checking voltages before replacing the part is never a bad idea.
But I will say that replacing the ID sensor is more cost-effective than replacing the drum, provided that running SP3-001-002 and checking values points you in that direction.
