3 Document Control Setting Document control The document control function is used to embed a document control pattern on the paper when a copy, print job, received fax, or list print 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 original sizes or types, certain paper sizes or types, or certain settings are used. To enable effective operation of the document control function, observe the following points. O Original O The function may not operate correctly if the original consists of large proportion of photographs. O The document control function is intended to protect text data, and thus it may not operate correctly if used to protect graphic data. O Paper on which the document control pattern is printed O 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. O Use B5 or larger size paper. The following paper sizes can be used: SRA3, A3W(12" x 18"), SRA4, A3, B4, A4, A4R, B5, B5R, 11" x 17", 8-1/2" x 14", 8-1/2" x 13-1/2", 8-1/2" x 13-2/5", 8-1/2" x 13", 8-1/2" x 11", 8-1/2" x 11"R, 7-1/4" x 10-1/2"R, 8K, 16K, 16KR 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. 25
