Sharp MX-FR20U ユーザーズマニュアル

19

The document control function is used to embed a document control pattern on the paper 
when print job is printed.
If a person attempts to scan a document with an embedded document control pattern on a 
SHARP machine that has the document control function enabled, the message "Document 
control pattern is detected. This job is canceled." will appear and an e-mail will be sent to 
the administrator.
This prevents secondary copying and faxing of sensitive documents.

Document control may not be effective when certain paper sizes or types, or 
certain settings are used.
To enable effective operation of the document control function, observe the 
following points.

●

Color of document control pattern (MX-FR20U only)

●

Select a color in a color family that is different from the paper color. 
(MX-FR20U only)

●

Paper on which the document control pattern is printed

●

To allow selection of the colors black, cyan, and yellow, use Sharp 
recommended paper. (MX-FR20U only)

●

White paper is recommended. If paper other than white paper is used, the 
document control pattern may not be detected and the function may not 
operate correctly.

●

Use B5 or larger size paper.
The following paper sizes can be used:
A4, B5, 8-1/2" x 11", 7-1/4" x 10-1/2"R, 16K

Disclaimer
Sharp does not guarantee that the document control function will always operate 
effectively. There may be some instances in which the document control function does 
not operate effectively.
