= Edge Erase =
•
The 64 LEDs are turned ON and OFF as necessary to erase unnecessary
charges along both the front and rear edges of the image as well as those
deposited in a reduction mode. This economizes on toner consumption and
prevents black streaks from occurring on the copy.
•
Which LEDs are turned ON for edge erase depends on the copy paper size
and zoom ratio setting. In the full size and enlargement mode, it depends
on the copy paper size, while in a reduction mode, it depends on the zoom
ratio and copy paper size.
•
Since the copy paper is fed through the center of the copier in this copier,
LEDs are turned ON as detailed below for different copy paper sizes. We
call the table LED ON Pattern A which is used to control edge erase in the
full size and enlargement mode. Edge erase is also provided for multi
bypass copying in which this copier detects the paper size (in the
crosswise direction only).
