Color Lock Out
Called Black Only Mode in C52x models.
Select On when printing for extended periods with only black toner. This saves the toner cartridges (cyan,

magenta, and, yellow toner cartridges and their matching photoconductor units must be removed from the
printer.
Select Off (default) when printing with color toner.

Printing Quality Test Pages message appears, then the pages print. The message remains on the
operator panel until all the pages print.
Press Select ( ) to print the pages. The Print Quality Test Pages contain several pages. The first page which
is printed in English text only contains a mixture of text and graphics. The information includes values of the
Quality Menu settings in Settings and printer and toner cartridge configuration information. The remaining pages
only contain graphics. For samples of the pages, see
“Print quality test pages (Prt Quality Pgs)” on
page 3-10 .
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.
Selections are Off and the values 1 through 5, with 2 as the default. Values 1 through 5 indicate the amount of
color remaining beneath the black content. Each setting increments by 1/600 of an inch. The more inaccurate
the registration setting, the higher the setting needs to be adjusted. Selecting Off disables color trapping.
