4.1.3 Trailing Edge Erase
The entire line of LEDs turns on again to erase the trailing edge after the
latent image has passed. This prevents the trailing edge from appearing on
the copy. The LEDs stay on to erase the leading edge of the latent image in
the next copy cycle. After the final copy, the erase lamps turn off at the same
time as the main motor.
