These parameters cannot be accessed from remote user interfaces.
Operation when updating firmware using USB memory
The USB host is always enabled when update firmware is selected in Service Mode.
After the update is completed and the device restarted, the state of the USB host is again dependent on the value of the System Settings parameter.
2.1.12 Searchable PDF
A searchable PDF file consists of pages of scanned images that have been put through OCR processing. The test data is extracted, and is laid over the original images
in the form of invisible text so that a search may be run for a particular segment of the data. A search in a PDF file requires a PDF browser application (e.g., Adobe
Acrobat, Adobe Reader). Or, Windows' search function may be used to look for a string of characters. Here again, the target of transmission must be an e-mail
address or a file server. To make use of this function, PDF (OCR) is specified when selecting the file format on the Transmission screen. A PDF file that will be
generated in response will consist of the following:
-Imaging Block
Transmission from a Box as well as reception transfer is also supported.
Supported Languages
Japanese, Latin 1, Latin 2, Estonian, Lithuanian, Russian, Greek
The characters that may be read by OCR are limited to those in English and the display character set of the UI, and then other characters will not be extracted.
Recognized Fonts
Japanese Mincho/Gothic
English Helvetica, Courier New, Times New Roman
Characters in a font other than the foregoing may show a drop in the rate of recognition.
Recognized Characters
Japanese: JIS non-Kanji, JIS Level 1, JIS No. 2 (547 characters), Roman numerals, circled numerals
English: alphabet characters, numerals, symbols (52 + 10 + 30), Euro symbol
Others: specific characters unique to English and some languages
The characters must be black on a white background to be recognized.
Recognized Character Size
Japanese: 8 to 48 pt (300 dpi)
A higher point size applies to 2-byte characters.
English: 6 to 72 pt (300 dpi)
If smaller than the lowest point size, the rate of recognition is likely to drop appreciably.
Limitations on Characters
Japanese:6000 characters (approx.) or less on a page
English:for a single character area, 130 characters or less per line, 100 lines or less
Characters outside the foregoing limitations will not be processed by OCR.
Characters Tending to Cause OCR Failure
-on an original with a complicated layout
-on an original with excessive noise
-on an original scanned in photo mode
-on an original scanned at an appreciable angle (slant)
2.1.13 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 rotating the
image, if necessary, so that the user need not concern himself with the orientation of the document 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.
2.1.14 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 processing. When transmission is executed with the File Name OCR button checked (part of transmission settings),
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 max-
imum 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].
