7) The Power indicator on the left shines blue, and the Status indicator on the right
blinks yellow-orange: indicates that the VTM300 is performing calibration.
11. Barcode recognition function:
1) The VTM300 supports 1D barcode and 2D barcode recognition.
2) Supports many kinds of barcode, for example: EAN, EAN8, Code 39, Code 93,
Code 128, UPC-A, UPC-E, ITF-14, ITF-16, NW-7, 12 of 5 and QR code.
3) The VTM300 currently supports front side and rear side single barcode
recognition.
4) Recognition
speed:
It depends on the image file size, resolution and the search settings. The
smaller the file, the higher the resolution and the smaller the search criteria
is, the faster the speed.
If the file size is small (resolution: 200 dpi), black and white, search in the
specific zone, the VTM300 can recognize single QR code in 1 second.
5) Recognition
rate:
The recognition rate for 1D barcode and QR code is almost 100%.
6) To reach the high recognition rate, the barcode images should meet the
following criteria:
The resolution is equal or higher than 200 dpi.
The barcode image is not distorted or is mot interference by noises (such
as horizontal and vertical lines, dirt, text, etc.).
The barcode generator should meet the standard of ISO / IEC 18004.
The printer prints clear.
7) The following situation may lead to bad recognition:
The barcode is covered by something (such as texts, images etc).
The barcode is not clear enough (for example: the image is serrated
seriously.).
The barcode size is too large and it takes too much time for calculation.
12. No-image-required calibration:
1) The VTM300 is already calibrated in our factory, and the calibration data is
saved in the scanner. In normal condition, user doesn’t have to perform
calibration like ordinary scanner does.
13. Scan counts function:
1) The VTM300 is built with scan counts function and it is easy to get total scan
counts for maintenance reference.
2) There is special design software for viewing scan counts. It is very useful for the
maintenance person.
14. Paper static electricity export function:
1) The VTM300 is designed with static electricity export function to avoid paper
static electricity accumulation.
15. The VTM300 cover open direction is selectable:
1) There are 2 directions for VTM300 to open the cover, one is open from the front
and the other is open from the back.
2) Customer can decide the cover open direction.
