TRAIL EDGE ERASE

Normally, the erase lamps turn on after the trailing edge of the latent image
has passed. Therefore, a trail edge erase margin cannot be observed on the
copy. Trail edge erase ON timing is the same as charge corona OFF timing.
During enlargement or reduction, the trail erase ON timing changes according
to the paper size and the reproduction ratio.
