SMOOTHING
7. SMOOTHING
When the fax unit prints a received fax image, the FCU converts the data into
either 400 x 400 dpi, 16 x 15.4 l/mm, or 15.4 x 16 l/mm (image rotation)
resolution, and smooths the image. The FCU then sends the smoothed data
to the printer in the 64 gradation levels + 3 laser pulse positions format used
by the base copier.
