Dors 800

Description

This mode is used for checking the number of banknotes in the formed batch: on the one hand there is no need to check the banknotes’ authenticity; on the other hand it is required to verify the number of banknotes quickly.

Types of control

Visible image of banknote is examined through full-length CIS (contact image sensor). This type of detection allows to discover the counterfeit banknotes which differ from the original ones in visible range.

Infrared (invisible) image of banknote is examined through full-length CIS. This type of detection allows to find the counterfeit banknotes which differ from the original ones in IR range.

Comparison of visible and IR images, alignment of images. Often the counterfeit notes have well reproduced visible and IR images. Though it is difficult to achieve the alignment of images. This type of detection allows detecting the counterfeit banknotes which looks absolutely like the original ones in IR and visible light.

Several ultraviolet (UV) sensors working on transmission and on reflection provide the full control of banknote paper background luminescence. This type of control allows to detect the counterfeit banknotes which differ from the original ones in UV range.

The magnetic sensors group consists of the central 6-channels sensor and 2 magnetic side heads. Such position of sensors fully covers the magnetic marks of US Dollars, Euro and other world currencies.

The paper optical density is an average value of IR transmission passed through banknote. This is the basic level of control obligatory for every banknote counter. These sensors allow to control the evenness of banknote passing through machine.

Size control of a banknote.

The control of double notes, chains, notes with missing fragment is carried out in all counting mode.

Detection of jammed banknotes inside the device allows avoiding damage of large number of banknotes. Usually jams are caused by foreign objects in the path (paper clips, paper, etc.). In this case the first counted banknote gets jammed, though DORS 800 stops counting in order to avoid damage of other banknotes.
