What about QC on mammography processors that are also used to develop films for copying mammograms and for laser films that are used in digital mammography?

Films that are used to copy mammograms (duplicating or copy films but not laser films) generally alter the performance of the processor by degrading the chemicals in the processor. This does not significantly affect processor performance if a small number of copies are made at a time. However, if a large number of copies is produced on a given day, FDA recommends that the daily processor QC tests be performed after the copies have been processed and prior to processing the clinical images.
