• The Domino serial number is a string of numbers and letters unique to your unit that helps us identify your product and look up information regarding this specific product. Please look to the underside of your unit for the serial number.
  

An example serial number is shown below. The format will always be the same, 6 numbers, followed by ‘DOM’ and ending in 5 numbers: ######DOM#####

• The below cleaning guide is available as a printable document listed in the Documents section of this page.

1. Please make sure the unit is turned off and disconnected from its power cord before cleaning. DO NOT use solvents such as thinner, alcohol, etc to clean the machine.  
2. First, wipe away dust with a soft microfiber cloth that is provided with Domino. For the best result, it is recommended to use an air duster and a soft bristle brush to remove any dust or debris from the interior of the unit.  All Parts of the Kolibri Domino need daily care and cleaning. Pay close attention to the sensors, which are delicate components. If any dust or other foreign matter adheres to the sensors, it may cause various problems during operation of the machine  
3. Refer to the photos and illustration below showing the location of the Kolibri Domino sensors.

The sensors you will need to address are:

• Hopper Sensor (1)
• Stacker Sensors (2)
• Inner Sensors of the Upper Sensor Block (3)
• Inner Sensors of the Lower Sensor Block (4)

• Kolibri suggests to clean the unit at least once per week. For heavy use locations and operations, it is recommended to clean the unit daily to avoid heavy buildup that may cause improper operation. When the unit is not in use, Kolibri suggests to cover the unit with a dust cover. 

• If there is a too much force on the motor, it automatically shuts off and displays the ‘JAM’ error code. Jamming may be caused by the following cases: 

1. If bills are fed incorrectly into the Kolibri Domino, 
2. If bills have foreign objects like clips, etc.   
3. If a bill enters the path crookedly 
4. If bill guides are not installed properly  Please refer to the below diagram for proper loading:

• If bills are very worn, torn, ‘soft’, or in folded, the bills may crumple in the bill path and get stuck.  
• If jamming occurs frequently, there may be an issue with the feed gap adjustment. If the gap is too wide, the Kolibri Domino will be able to accept more than one note at a time into the bill path which will frequently cause jamming. To learn how to adjust the feed gap, please refer to Section 6: What is a feed gap? How do I adjust it?

• The feed gap is the actual height of the bill feed path, and should be tuned to just about the thickness of a single bill. If the feed gap is too wide, the user may experience a high amount of DOUBLE and CHAIN errors which are caused by more than one bill entering the scanning path at one time. If the feed gap is too tight, the unit may not be able to pass bills into the scanning path, or catch on bills and tear them. 
• For feed gap adjustment procedure, a printable document is available in the Documents section of this page. The following steps are the procedure for adjusting the feed gap: 

1. Ensure the machine is turned off.
2. Position the rollers so that none of the rubber teeth are visible. This can be done by turning the kick rollers. Only the black smooth sections of the rollers should be showing. 

3. Place one bill that is crisp and rigid enough to prevent bending during the adjustment procedure. Place it lengthwise either to the right or left side of the hopper. See below image for example.

4. Guide the bill between the inner rollers during this step; you should feel moderate resistance as you move the bill back and forth through these rollers. In other words, the gap between these rollers is wide enough to pass just one bill per count, but narrow enough to feel a slight tension or friction when pulling the bill out.

• To adjust the bill feed gap, use the instructions below to turn the adjustment screw at the top of the unit:

1. Make a slight turn at a time, then retest. 
2. If the bill feels too loose, tighten the feed gap by turning the adjustment screw clockwise. 

Important Note: The Kolibri Domino’s feed gap adjustment can be sensitive during adjustments. Do not overturn each adjustment or you may overshoot the optimum gap. We recommend testing with a stack of bills after each adjustment turn. 

• The Kolibri Domino is designed to detect and flag any suspected counterfeit notes. This unit provides 2 CIS, UV, MG, and IR anti-counterfeit feature detection. To learn more about detection techniques, please refer to Section 9: What do MG, UV, and IR stand for? What’s the difference? 

• There are 3 main counterfeit detection techniques used in the majority of discriminators and detectors: 

• MG – Magnetic Feature Detection – US currency uses specific magnetic ink at exact locations to provide a unique magnetic Kolibri Domino on each denomination note. By scanning each bill for the presence and location of these features, the Kolibri Domino is capable of detection the minute magnetic signals present on these bills and will flag any notes that do not have these features present, in the correct locations. Certain counterfeit notes do not have the same features and will be rejected by the Kolibri Domino as ‘SUSPECT’. 
• UV – Ultraviolet Feature Detection – Certain features are hidden to the naked eye on all US currency. In order to detect these features, the Kolibri Domino has special ultraviolet emitters and sensors capable of detecting the exact ultraviolet anti-counterfeit features built into each denomination note. These are referenced against known-genuine currency and used to flag any notes that do not display the correct UV features on the suspect notes.  
• IR – Infrared Feature Detection – Similar to UV, US currency contains hidden infrared features that can only be detected by infrared illumination and detection. The Kolibri Domino scans each bill for the presence and accuracy of these features and fails any bills not meeting these criteria as ‘SUSPECT’. 

• There are a few reasons that a detector may flag genuine currency as suspect. If bills are worn, bent, torn, or crumpled, the anti-counterfeit features needed to verify a bill as genuine may be compromised. For example, the magnetic ink on a note may wear over time or heavy use, reducing the magnetic response to below detection thresholds. If the Kolibri Domino cannot verify the correct features expected on a note, the unit will flag that currency as ‘SUSPECT’. 

• If sensors are dirty or damaged, the Kolibri Domino will not be able to detect the necessary anti-counterfeit features needed to verify currency as genuine. 
• Another possible reason is that the detection sensors may be incorrectly calibrated, lost reference, or be under operating conditions that cause false positives. In order to reduce these error types, it is advised to operate the unit out of direct sunlight and reduce interference that may cause sensor errors. If this occurs frequently under normal operation, please contact Kolibri support for troubleshooting or service. 

• One of the most common reasons for miscounting is improper loading of the currency to be counted. In most cases the Kolibri Domino will display an error and prompt the user to reload the currency. 
• The second most common reason for improper counting is poor maintenance of the unit. Each sensor needs to be clean and free of debris to operate correctly. Due to the complexity of the sensing mechanisms, the unit must be able to sense all features which are expected on genuine currency. Both ‘SUSPECT’ errors, and wrong denomination may occur if sensors are obscured.  

• In rare cases, electromechanical failure of the unit will cause all notes to be sensed incorrectly. For frequent, repeatable improper denomination errors, please contact Kolibri Support for repair. 

• Depending on the mode the unit is set to, the number of rejects may vary greatly. For example, in sort mode of a highly mixed stack of notes, ALL notes which do not match the first bill passed through the unit will be rejected.  

• Yes, the Kolibri Domino uses advanced sensing to determine the denomination of the notes being scanned and automatically counts the correct total of the currency being counted, or sort out notes as the user specifies. Depending on the mode, when undesired note passes  all sensors, count stops, appropriate message displays on TFT screen. 

• Yes, the Kolibri Domino uses advanced sensing to determine the denomination of the notes being scanned.

• To connect a printer use adapter cable provided with the unit. Insert one end of the adapter into the RJ11 Port (please refer to 1.5 “ View of the Kolibri Domino” section of the user manual. The other end of the adapter should be connected to the printer’s cable.

The Kolibri Domino uses a F2A250V 20mm Length by 5mm Diameter fuse next to the AC power inlet (where the power cord inserts to the back of the unit, please see picture below) Check this fuse if the unit does not power on. If replacing the fuse does not solve power-on issues, please contact Kolibri Customer Service.
