I have the same issue but on a C552, is there away to blow out the sensors from inside the machine, say by removing all IU's then blower brush air through the back of the machine, or is that a bit hit & miss!?

Unfortunately it's not that easy, you have to access it from the back.
So what do I need to remove to clean these sensors on a C452? & how long should I allow to do it?
Thanks

according to the manual I can see these here Screenshot by Lightshot and actual sensors here Screenshot by Lightshot
BUT the question - where to stick air blower trying to blow these sensors? Do i need to dismantle PWB-MFP plate to reach them? What to unscrew to swing controler board?

What should I take out reaching them for a blow?

updates - from yesterday was trying to get to the main drive. So i did it (8 hours of continuous work, was trying to do it very accurately). Still don't know how to dissemble it and actually afraid to - because I think will need to calibrate main drive unit?
But anyway decided to blow with air. Were looking a best spot to blow and I have noticed the thin encoder disk. while rotating motor - I can see it is bent a little on one side.
Here are the pictures

Should I start looking a new main drive unit or take out all drive unit and try to unbend the encoder disk? possible?
