Discussion
Which of the following is considered individual characteristics of a photocopy ?
Answer: B
The individual characteristics of a photocopy are trash marks.
Trash marks are extraneous marks, such as specks, spots and lines, produced by dirt, scratches or defects on the glass platen, the drum or the lid of a particular photocopier. They repeat on every copy made on that machine until it is cleaned or repaired, so they can link a copy to a specific machine and period of time.
The other terms are not the standard name for these marks; features such as the general toner type and image quality are class characteristics shared by many machines.
