Complete sentence

[jw1212]

I read a statement from a public domain and have difficulties to understand its grammar structure because I can only find the subject but the verb. Please read the following:

" An imaging system in which a light source illuminates the photoreceptor so as to erase that photoreceptor after development of a first toner followed by a high slop AC corona system which recharges both the photoreceptor and the first developed toner before exposure and development the next color image."

I use a limitation of the modification to simplify this statement.

First step to remove the modification of the “AC Corona system” then it becomes:
"An imaging system in which a light source illuminates the photoreceptor so as to erase that photoreceptor after development of a first toner followed by a high slop AC corona system."

Second step to remove the modification of the result of the illumination then it becomes:
"An imaging system in which a light source illuminates the photoreceptor."

Third step to remove the modification of the “in which” and it becomes:
"An imaging system"

So I believe I read the statement with a subject but missing verb that makes the whole structure as a non-complete sentence.

Please let me know if I do the analysis correctly.

Thank you very much!

It's incomplete, but does it have to be a complete sentence or the best possible description. You could put 'it is' at the beginning, which would make it complete, but would it improve the description?
