Dual Scan ADF sensor cleaning

[Genotrom]

I have seen Dual Scan ADFs that are very resistant to jams. But I have some printers with jams around (66-13).
I have difficulty getting to the sensors in these ADFs. In normal DFs, it is sufficient to remove many screws but it is easy to get to the sensors. On ADF Dual Scan the covers blocked access to that area.
What technique do you use to get into those sensors quickly?

For now, I've never needed to disassemble. But if I remember correctly, you have to disassemble the two side covers to remove the one under the rollers.

Check service manual for 'remove the lower guide assy'.

An air can does the job.
No need to rip apart.
