Print quality menu
Under the Print Quality menu in HP Toolbox, there will be an Optimize section containing a number
of On/Off adjustments which will apply to all media types.

Adjustment type Default setting Extended print mode Description
Background Toner Off EEC95-9 Will reduce the developer
DC bias
Extra Cleaning Off EEC93-11 Increases rotations of the
ETB
Trailing Edge
Over-development
(full-speed)
Off EEC95-14
Trailing Edge
Over-development
(half-speed)
Off EEC95-14
Mottle Prevention Off EEC96-12 Will increase the developer
DC bias
Less Duplex Transfer Current Off EEC68-10
EEC91>16h

Decreases transfer bias on
the 2nd side of duplex jobs.
For media that has low
resistivity after fusing.
More Duplex Transfer Current Off EEC68-10

Understanding print-quality settings
Print-quality settings affect how light or dark the print is on the page and the style in which the
graphics are printed. You can also use the print-quality settings to optimize the print quality for a
specific media type.
You can change the settings in the device properties to accommodate the types of jobs that you are
printing. The following settings are available, depending on the printer driver that you are using:
Ŷ Draft (600 dpi)
Ŷ Normal (Image REt 2400)
