If there are issues such as jamming, misfeeding, or tearing of bills it could be for the following reasons:

• Wrong bill loading, damaged or wrinkled bills. For proper use, please check the “Bill Loading Procedure” document.
• Improperly set feed gap. Please check the “Feed Gap Adjustment” procedure.
• Open the top cover of the unit and make sure the sensor block is properly closed. Please check the “Cleaning Procedure” document to locate the sensor block.

For optimal performance, it is advised to limit the counting to no more than 200 bills at a time.

Regular care and cleaning of the Kolibri KBR-500 are essential to maintain its performance and ensure longevity. Here are some important steps to follow:

1. Turn off and unplug the machine before cleaning to avoid any risk of electrical hazards.
2. Use an air duster and a soft bristle brush to remove dust or debris from the interior of the unit. This helps prevent buildup that could affect the performance of the sensors.
3. Clean the sensors (Hopper, Stacker, and detection sensors) using the provided soft bristle brush or a dry cloth. Clean these components frequently to avoid dust accumulation, which could lead to errors or malfunctions.
4. Clean rubber rollers with a slightly damp cloth. You may use a small amount of isopropyl alcohol to dampen the cloth. After cleaning, allow the rollers to dry completely before turning on the machine.
5. When not in use for extended periods, cover the unit with the provided dust cover to prevent dust from settling inside.
6. Weekly maintenance is recommended for optimal performance. For heavy usage, consider cleaning the machine more frequently to avoid buildup that could affect its operation.

By following these steps, you can maintain the Kolibri KBR-500 in top condition and extend its lifespan.

Kolibri suggests cleaning 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 covering the unit with a dust cover.

To properly adjust the feed gap on the Kolibri KBR-500 and resolve issues like DOUBLE or CHAIN errors, follow these steps carefully:

1. Power off the unit before making any adjustments to ensure safety.
2. Locate the feed gap adjustment knob, which can be found at the back of the unit.
3. Adjusting the feed gap:

• If you are encountering DOUBLE or CHAIN errors (multiple bills feeding at once), the feed gap is likely too wide. To fix this, tighten the feed gap by turning the adjustment knob clockwise. Start with a half-turn, then test the machine. Continue adjusting in half-turn increments, retesting after each adjustment, until the problem is resolved.
• If the machine is experiencing bill jams or the bills are being torn at the input, the feed gap is probably too narrow. To correct this, loosen the feed gap by turning the knob counterclockwise. Again, start with a half-turn, test the machine, and continue adjusting in half-turn increments as needed.

4. Important Note: The feed gap adjustment is sensitive, so proceed with small adjustments. Always test the unit with a stack of bills after each change to ensure the feed gap is correctly set. This method will help maintain smooth operation of the KBR-500.

KBR-500 like all other discriminators on the market with integrated detectors, cannot guarantee a counted bill to be genuine or counterfeit.

There are several reasons a genuine bill may be recognized as counterfeit, or vice versa. Possible reasons include: direct sunlight exposure, worn bills, excessively dirty bills, or highly advanced counterfeiting techniques used to produce the bill. Separate equipment may be required to definitively determine whether a bill is counterfeit.

Yes, in MIX mode, KBR-500 counts a mixed batch of $10, $20, $50, $100 bills together, non-stop, quickly.

KBR-500 is designed to detect and flag any suspected counterfeit notes. This unit provides UV, MG, IR line anti-counterfeit feature detections.

There are 3 main counterfeit detection techniques used in most discriminators and detectors:

• MG (Magnetic Detection) – US currency uses specific magnetic ink at exact locations to provide a unique magnetic KBR-500 on each denomination note. By scanning each bill for the presence and location of these features, the KBR-500 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 KBR-500 as ‘SUSPECT’.
• UV (Ultraviolet Detection) – This feature checks for UV-sensitive marks on bills that are invisible under normal light. Genuine currency often contains UV-reactive elements that glow under UV light. Counterfeit bills may lack or have irregular UV features, helping to differentiate them.
• IR (Infrared Feature Detection) – Similar to UV, US currency contains hidden infrared features that can only be detected by infrared illumination and detection. The KBR-500 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 a suspect. If bills are taped, 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 KBR-500 cannot verify the correct features expected on a note, the unit will flag that currency as ‘SUSPECT’.

If sensors are dirty or damaged, the KBR-500 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. 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 Technical Support for troubleshooting or service.

One of the primary causes of miscounting arises from incorrect loading of the currency into the machine. Typically, when this occurs, the KBR-500 will detect the error and prompt the user to reload the currency.

Another significant factor contributing to inaccurate counting is inadequate maintenance of the unit. Each sensor must remain clean and clear of any debris to ensure proper functionality. Given the intricacy of the sensing mechanisms, the unit must accurately detect all features expected of genuine currency. Failure to maintain cleanliness may result in both ‘SUSPECT’ errors and incorrect denominations.

In rare instances, electromechanical issues within the unit can lead to incorrect sensing of all notes. If improper denomination errors persist consistently, please reach out to Kolibri Technical Support for repair assistance.

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. Another example is FACE mode, where all notes with the same face up on the first note passing through the unit will be rejected.

If sensors are dirty or damaged, the KBR-500 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. 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 Technical Support for troubleshooting or service.

Yes, the Kolibri KBR-500 uses advanced sensing to determine the denomination of the notes being scanned and automatically counts the correct total of the currency being counted or sorted out notes as the user specifies. Depending on the mode, when an undesired note passes all sensors, the count stops, appropriate message displays on the TFT screen.

Yes, the Kolibri KBR-500 uses advanced sensing to determine the denomination of the notes being scanned.

The contact image sensor (CIS) within the unit is precisely calibrated at the factory. However, with regular use, the sensor’s sensitivity may alter, potentially causing False Errors. To address this, the unit can be recalibrated using the white calibration card provided with the product.

Please download the calibration procedure document and follow the steps to resolve this issue.
