Notes about and limitations of file types

Originals scanned in black and white are sent as TIFF files.

According to the settings specified for [Compression (Gray Scale / Full Color)] under [Scanner Features], originals scanned in full color or gray scale are sent in one of the following file types:

• [On] : JPEG file

• [Off] : TIFF file

When [Full Color: Text / Photo], [Full Color: Glossy Photo], [Gray Scale], or [Auto Color Select] is specified under [Original Type] and [Compression (Gray Scale / Full Color)] is set to [On] under [Scanner Features], you cannot select [TIFF] under [Multi-page].

Even if you select [TIFF] under [Multi-page], files stored in JPEG format are automatically changed to multi-page PDF files and then sent.

You cannot select [High Compression PDF] if:

• [Black & White: Text], [B & W: Text / Line Art], [B & W: Text / Photo], [Black & White: Photo], or [Auto Color Select] is selected under [Original Type].

• [Reduce / Enlarge] is selected.

• [100 dpi] is selected as the resolution.

• [Preview] is selected.

• When the WSD or DSM destination list is used.

If [PDF File Type: PDF/A Fixed] in [Administrator Tools] under [System Settings] is set to [On], [PDF] and [High Compression PDF] other than PDF/A cannot be selected.

Adobe Acrobat Reader 5.0/Adobe Reader 6.0 and later versions support High Compression PDF.

If [High Compression PDF] is selected as the file type, areas of uneven shade may appear in the document. If this is the case, change the PDF File Setting to [PDF/A ]or [PDF].

[Security Settings] in the PDF File Setting cannot be selected.

You cannot select [OCR Settings] if:

• [TIFF / JPEG] or [TIFF] is selected as the file type.
