2.3.5 IMAGE QUALITY SP ADJUSTMENTS
Adjustments are easier with this machine, because the parameters have been grouped and no longer have to be adjusted one by one.
In this section, we will cover the custom settings for each of the 5 original modes: These custom settings are:
•Image Quality
•Line Width Correction
Settings adjustable for each original mode will also be covered (these do not just affect the custom settings; they also affect all sub original modes, such as sharp text).
•Independent Dot Erase
•Background Erase

If the value is increased, the outlines of lines become sharper but this could cause moiré to appear in dot patterns. If the value is decreased, image patterns become smoother, the occurrence of moiré decreases, but the corners of characters and intersections of lines at acute angles may not be as sharp.
There are two sets of custom settings for photo mode. One is for dithering, and one is for error diffusion. The set of custom settings that will be used depends on the setting of SP4904 002. The possible settings are:
0Dither (106 line)
1Dither (141 line)
2Dither (212 line)
