Having issue with pdf that contents image to readable (searchable) pdf

[System22640200kiod]

I m able to convert to searchable pdf but that does not translate to its readability in order to satisfy ADA complaince. In other words, it still recognizes document as image and won't read (by NVDA screen reader). Please help.

One thing I learned is that ability to make a pdf searchable does not automatically mean readable for ADA 503 compliant.
