PRINTER►CONVENIENT PRINTING FUNCTIONS
• "Hidden Pattern Print" is a function provided for the purpose of deterring unauthorized 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 (administrator)", 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.
