(5) Image capturing operation
1) When the scanner receives an IMAGEOUT command, it captures an image, beeps three times, and switches to the
image transmission mode (Xmodem 1K protocol).
2) When the thumbnail is enabled:
The scanner transmits a thumbnail (BMP file in 1/64 VGA) repeatedly.
If you press the trigger switch, the scanner beeps once, captures an image, and starts transmission (Xmodem 1K
protocol).
When the thumbnail is disabled:
The scanner immediately captures an image and transmits it in the format specified by IMAGEOUT parameters
(Xmodem 1K protocol).
3) Upon completion of transmission, the scanner beeps once and exits the image transmission mode.
(6) Notes
• Image transmission can only be command-controlled; it cannot be started by the QR-coded parameter menu.
• When the scanner is in the image transmission mode, it cannot scan bar codes or 2D codes. The protocol is fixed to the
Xmodem 1K.
• Parameters of the IMAGEOUT command should be uppercase or numerical ASCII characters.
• Transmission condition settings such as header, terminator and transmission speed for the image transmission are the
same as those for ordinary commands.
• Transmission speed and other conditions when the Xmodem 1K protocol is used are the same as those with the normal
communications protocol (non-acknowledge mode or ACK/NAK mode).
• Upon completion of image transmission, the scanner returns to the normal communications protocol (non-acknowledge
mode or ACK/NAK mode).
• In a JPEG file format, images are compression-converted, so the image quality may be lower.
(7) Image transmission time required (Typical)
The table below lists the typical image transmission time required from image capturing to conversion and transmission
under the following conditions: Xmodem 1K and 115200 bps. However, this may vary according to the settings made in
the host computer.

* In a JPEG file format, images will be compression-converted, so the file size may vary, depending on images
scanned (approx. 10 to 40 KB, normally 20 KB). You cannot set the compression ratio.
