NOTE: An SP code number and name set in bold italic denotes an SSP (Special
Service Program) mode. To access an SSP, enter the SP mode: press and
hold down  on the 10-key pad then "Copy SP" on the touch-screen.
Also, SP4904 007 adjusts the error diffusion process that is used in text/photo
mode.
Gray adjustment: At areas defined as edges, error diffusion is done on text to
create sharp lines to better define text characters, but in other areas, grayscale
processing for photographs is done. Select a lower setting for better reproduction
of photographs and a higher setting for sharper text. For details, refer to the SP
table.
