Color Trapping Uses an algorithm to
compensate for mechanical
mis-registration in the
printer. When small black
text or fine black lines are
being printed, the printer
checks to see if they are
being printed on top of a
colored background. If so,
rather than remove the color
from beneath the black
content, the printer leaves
the color around the edge of
the text or line. The hole in
the colored region is
reduced in size which
prevents the characteristic
white gap that is caused by
mis-registration.
This menu item applies to
PCL 5 emulation, PCL XL,
PDF, and PostScript.
1–5 (2)*
Off
Values 1 through 5 indicate the
amount of color remaining beneath
the black content. Each setting i
1/600 of an inch. The more
inaccurate the registration setting,
the higher the setting needs to be
adjusted.
Select Off to disable color trapping.
Size Sensing Turns the automatic size
sensing for print media
input sources either On or
Off. Tray 2 Sensing
Auto*
Off
This is a two-level menu that
displays only those print media
sources which support automatic
size sensing.
Auto is the same as On.
Panel Menus Lets the system support
person enable or disable
the operator panel menus.
The advantage of disabling
the menus is so users
cannot change values for
the printer once the system
support person has set
them for the majority of the
users.
Enable*
Disable
This menu item only appears when
the PJL PASSWORD Environment
variable is set to 0.
PPDS Emulation Determines if the printer
can recognize and use the
Personal Printer Data
Stream (PPDS) emulation
language.
Deactivate*
Activate
This menu item only appears if the
PPDS interpreter is available.
Download Emuls Lets the system support
person turn the download
emulator off.
Disable This menu item only appears if one
download emulator is installed.
An Enable value is unnecessary
because the printer automatically
re-enables all download emulators
after two instances of a power-on
reset for the printer. To re-enable
these emulators, a user would
perform another power-on reset
after exiting the CONFIG MENU.
Demo Mode Lets marketing personnel or
merchandisers demonstrate
the printer to potential
customers by printing the
demo page. Deactivate*
Activate
Select Deactivate to turn Demo
Mode off.
