# PRINTING PATTERN DATA(HIDDEN PATTERN PRINT)

## Overview

This function prints pattern data such as "DO NOT COPY" behind the print data.
If paper with pattern data is duplicated, the pattern data emerges in the background, which will help to prevent information from being leaked through unauthorised document copying.

- This function is available in a Windows environment.
- This function can be used when the PCL6 or PCL5c printer driver is used.

## Operation

Windows
Click the [Advanced] tab.
Select the [Hidden Pattern Print] checkbox so that the checkmark appears, then click the [Settings] button.
The hidden pattern printing function cannot be used when "Print Mode" is set to [Ultra Fine].
Configure the settings for hidden pattern printing and click the [OK] button.

- "Hidden Pattern Print" is a function provided for the purpose of deterring unauthorised printing. It does not guarantee the prevention of information leakage.
- Text may not be completely hidden on an output sheet with a pattern print under certain machine conditions. In "Setting mode", select [Security Settings]→[Hidden Pattern Print Setting]→[Contrast] if this is the case.
- The hidden pattern may not emerge on copies with certain types of devices or under certain setting conditions used to copy an output sheet with a pattern print.
- When the colour mode is set to [Black and White] or when it is set to [Automatic] and the original is recognized as black and white, a black background pattern is printed even if a cyan or magenta pattern is selected.
