of grays, select a lighter Print Darkness setting (Lighter or Light-
est). Select a darker setting (Darker or Darkest) for bolder text and
darker gray scales.
You can change the Print Darkness setting for all resolutions.
Toner Saver
Toner Saver preserves the toner supply by reducing the amount of
toner on the printed page. This may help lower the cost of printing.
Toner Saver is recommended when printing rough drafts, since
print quality is reduced. Setting Print Darkness to a lighter setting,
with Toner Saver Off, is another way to conserve toner.
When Toner Saver is on at 300 dpi and 600 dpi resolutions, there
are five independent levels of Toner Saver available by changing
the Print Darkness setting. Choose a darker setting for higher qual-
ity, or a lighter setting for higher toner savings.
When Toner Saver is On, the setting for 1200 Image Quality is
ignored.
When Toner Saver is on at 1200 dpi resolution, one level of Toner
Saver is available. When both Toner Saver and 1200 dpi are
selected, the setting for Print Darkness is ignored.
PQET
At lower resolutions, printed characters can appear to have jagged
or uneven edges. Print Quality Enhancement Technology (PQET)
smooths the edges of printed characters to improve the appearance
of the text. It may also improve the smoothness of diagonal lines in
basic line art.
While setting PQET On improves the print quality of text, it may
adversely affect the appearance of some scanned images or half-
tones. If you notice reduced print quality with those images, turn
PQET Off.
