When you do a pm on these big Toshiba's, a lot of techs forget the 08-290....This is a very important code to run on the pm. Also clean the slit glass before running the codes. Also SOME techs don't clean the used toner hopper at pm. You must do this. AND don't just dump the old developer, vacumn the unit out after removing the sensor, or you will have developer problems quicker that you should!

Please reply and tell us if you resolve the problem, I've had similar problems with eS520/600/850, the PM is ranked for 400K it shouldn't have problems after 80K in most of my cases it gets overtoned after I clean the machine

Nah...
I don't know about you guys, but the era of "blowing toner sensors" with your vacuum cleaner went out in the 80's, when vacuums that were not static-dissipative were still around. I have been DIRECTLY vacuuming developer units for as long as I can remember without removing the toner sensors, and have not blown one since a Mita 1205 in (like) 1982.
As far as I know, all modern vacuums are static-dissipative and this prevents static buildup in the hose, which is what caused the problem decades ago.
Although this may be a "preventative" measure, it's one that I feel has not a lot of merit.

These Toshiba's are pretty weird, I wasted a lot of time troubleshooting what it looked to be an overtoned DV unit going up and down on calibration (05-200, default is 128) and nothing, turns out the problem was the drum, eventhought it looked good, somehow it was sending the worng signal causing the dark copies with background, luckely I had another machine at the shop and that is how I found the problem was the drum and not the DV....
godd luck, please let me know if it worked....
