200 M ohm resistor ?

I notic a 200M ohm resistor was connected to the axia of the rubber
platen of the high speed printer. I belive the purpose of the resistor
is to drain the static charge create by the platen when
paper are feed in high speed. I am curious why a 200M ohm resistor was
selected instead of a zero ohm resistor. the 200M ohm can actually act
as a insulator,which is very poor in electrical conduction. Does any
person know the reason ? thank for any explaination.

I am curious exactly where you found a 200 MOhm resistor: Brand, location,
etc. These are kind of valuable for making op-amp circuits with high
feedback. These really high values are rather expensive, and at the same
time, I have access to spare parts from old computer and printer
equipment.
