Canon NP6010 service manual / replacing ozone filter

[Pharao]

[ladybird]

Take out the drum unit, the black plastic assy that the drum unit sits in is the frame of the filter(you can see the ozone filter with the drum removed). There is a white plastic clip at front & back of the assy, push them both in & the ozone filter will rack down. The ozone filter slides out of that assy.
