Problem Setting in Printer driver Cause and Remedy
A printer is installed under high-humidity
environment and the print density becomes
lighter. Special setting 1 When using the printer under high-humidity environment or depending on the
media used, the image of color letters or patterns with toners of two colors or
more may become lighter. In that case, if setting to "Special setting 1", the print
image may be able to be improved.
A printer is installed under high-humidity
environment and the print density of halftone
becomes lighter or the displacement of letters
occurs. Special setting 2 When using the printer under high-humidity environment or depending on the
media used, the print density of thin line or fine halftone may become lighter. In
that case, if setting to "Special setting 2", the print image may be able to be
improved.
A printer is installed under low-humidity
environment and the copy image fault occurs in
paper with a high value of resistance. Special setting 3 When using the printer under low-humidity environment or depending on the
media types, the marks like toner scatter around characters or patterns may be
printed. In that case, if setting to "Special setting 3", the print image may be
able to be improved.
The media with a rough texture is used.
Special setting 4
When using the media with a rough texture, the density of image, especially the
one with toners of two or more colors, may become lighter. In that case, if
setting to "Special setting 4", the print image may be able to be improved.
The reproducibility in halftone decreases.
Special setting 5
When not using the printer for a long period, the reproducibility in halftone may
decrease or the inconsistencies in density may occur. In that case, if setting to
"Special setting 5", the problem may be improved. In this mode, however, the
lead time for printing becomes a bit longer.
Fogging occurs in the whole image.
Special setting 6
When printing the image with a large blank area on the gloss paper, in some rare
cases, the fogging may occur in the blank area. In that case, if setting to "Special
setting 6", the problem may be improved.
The edge enhancement occurs.
Special setting 7
When printing the image with a high-density area, the edge enhancement may
occur in the area because the trailing edge of the area may be reproduced in high
density. In that case, if setting to "Special setting 7", the edge enhancement may
be improved.
