Document Orientation Auto Detection; Document Name Ocr - Canon DU7-1178-000 Service Manual

2.1.3 Document Orientation Auto Detection

Document orientation auto detection is available when PDF (OCR) is selected. When a PDF (OCR) file is
sent to an e-mail address or a file server, the result of OCR processing is used to identify the orientation
of the original (with reference to the orientation of characters), and the file is sent after automatically ro-
tating the image, if necessary, so that the user need not concern himself with the orientation of the docu-
ment for transmission. It is important to bear in mind, however, that any of the following types of
documents may be transmitted in the wrong orientation:
- whose characters are at an angle (+/-3 deg or more)
- which contains white characters against black background, uncommon font, or handwritten characters
- whose text is not at 300 dpi and is not between 10 and 20 pt
- whose characters per page are appreciably limited in number (ideally, there must be 50 characters or
more)
Memo:
A document may not fall under the foregoing types, but may still be transmitted in the wrong orientation.
If wrong orientation is too frequent, disable the function.

2.1.4 Document Name OCR

The file name OCR function is available when PDF (OCR) is selected. When a PDF (OCR) file is sent to
an e-mail address or a file server, a file name will be assigned with reference to the result of OCR process-
ing. When transmission is executed with the File Name OCR button checked (part of transmission set-
tings), as many characters as specified in Additional Functions will be collected from the head of the text
block on the first page and used as the name of the file. A maximum of 24 characters may be used, and it
may be combined with a name that has separately been assigned. All characters that follow the initial 24
will be cut out of the name.
Memo:
If the setting Additional Functions>Common Settings>Langage Switch is set to [ON] , 2-byte characters
will not be collected for the file name. If a name must include a 2-byte character, be sure to set the setting
to [OFF].
