• If you use the E-mail or Scan to PC service to scan a document with both [MRC High
Compression] and [Searchable Text] enabled, the recognition rate of the scanned data
may differ from that of the data retrieved from a folder with both [MRC High Compression]
and [Searchable Text] enabled, using CentreWare Internet Services.
• In the following cases, the Searchable Text feature may not function properly.
• If the document is not loaded correctly and thus the text is slanted, or if the text on the
document is in different orientations
• If the text on the document is decorated (italic, hatching, strike-through, etc.)
• If the document has background patterns or noise
• If the text on the document is handwritten
Note • This feature is not available for some models. An optional component is required. For more
information, contact our Customer Support Center.
