6.5 Scanning routing of bounding box
The bounding box will be measured by the Epos sensor during a fast scan routine. It is
interesting to know the principle behind this innovative scanning method.
The scanning routine will go through the following steps:
1 The laser will be activated to detect the background colour. This value will be used to
recognize the difference between background and box during the scanning procedure.
2 A diagonal scan will be executed at the set cutting speed in the firmware (user controlled)
3 A horizontal scan will be executed at maximum speed
4 The head goes back over the scanned path to verify
As from the moment the scan cycle detects 4 points, the position of the barcode is known
(situation 1 and 2). When there are less than 4 points detected, an intelligent feed of media
will be done and the same type of scan will be performed a second time (situation 3).
