Size sensing

B5/Executive
Due to engine limitations, Trays 1 through 4 cannot simultaneously sense executive and JIS-B5-size paper. The value
of this setting determines which of the two paper sizes these trays will sense automatically. This setting will apply to
all automatic trays, but not to the MP Feeder. The MP Feeder can support these paper sizes regardless of the value of
this setting.

Tray [x] sensing

By turning the tray [x] sensing setting to Auto, every input option equipped with size sensing hardware automatically
registers what size of paper it contains. When this setting is turned Off, the printer ignores the size detected by the
hardware and treats the input source as a non-sensing source. The media size can be set by the operator panel or the
data stream.
To change this setting:
1
From the Configuration menu, navigate to SIZE SENSING. The screen displays each size sensing equipped input
source and its current Size Sensing setting.
2
Select the appropriate input source.
3
Touch Left or Right to change the setting.
4
Touch Submit to save the setting, or touch Back to return to the Configuration menu without saving any changes.

Print Quality Pages

The Print Quality Pages can be printed from both the Configuration Menu and the Diagnostics Menu. The Configuration
Menu is limited in information compared to the pages printed from the Diagnostics Menu.
To help isolate print quality problems, print the Print Quality Test Pages. The pages are formatted. The Printing
Quality Test Pages message appears, and 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 contain only graphics.

Color Trapping

Color Trapping uses an algorithm to compensate for mechanical incorrect 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, then rather than remove the color from beneath the black content, the printer leaves the color
around the edge of the test or line. The hole in the colored region is reduced in size, which prevents the characteristic
white gap that is caused by incorrect registration.
Values include Off and number 1‑5 (the default is 2). 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.
