The Signature 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 ‘SGN’ and ending in 5 numbers: ######SGN#####

  • The below cleaning guide is available as a printable document listed in the Documents section of this page.
  • ATTENTION: The unit should always be turned off and disconnected from its power
    cord before cleaning.
  1. First, wipe away dust with a soft microfiber cloth.
  2. If needed, clean the sensors using a can of compressed air (“air duster”, found at any electronics store).
  3. If this does not resolve the issue, continue cleaning with a cotton swab lightly moistened with isopropyl alcohol – gently wipe the sensors with the swab. You can purchase isopropyl alcohol at most pharmacies or supermarkets.

  • Kolibri suggests that the user cleans the unit at least once per week. For heavy use locations and operations, the user may clean the unit daily to avoid heavy buildup that may cause improper operation. When the unit is not in use, Kolibri suggests that the user covers the unit with a dust cover.
  • When the motor senses too much force, it automatically shuts off and displays the ‘CHAIN’ error code. Jamming may be caused by a few different cases:
  • If bills are fed incorrectly into the Signature, they may enter the bill path in a stack, or at a bad angle which may catch on internal components. If a bill enters the path crookedly, the unit is prone to jamming by bad feeding and may damage the unit and the notes as they pass through. Please refer to the below diagram for proper loading.
  • If bills are very worn, torn, ‘soft’, or 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 Signature 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.

Turn one of these rollers until only the black smooth section shows on back roller

Incorrect roller position

Correct position

  1. 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 images for examples.

  1. 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 are 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 an 1/8’’ adjustment turn at a time, then retest.
  2. If the bill feels too loose, tighten the feed gap by turning the adjustment screw counterclockwise.
  3. If the resistance against the bill feels too strong, loosen the gap by turning the screws clockwise.

Important Note: The Kolibri Signature’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.

  • There are 3 main counterfeit detection techniques used in the majority of discriminators and detectors:
  1. MG Magnetic Feature Detection – US currency uses specific magnetic ink at exact locations to provide a unique magnetic signature on each denomination note. By scanning each bill for the presence and location of these features, the Signature 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 Signature as ‘SUSPECT’
  2. UV Ultraviolet Feature Detection – Certain features are hidden to the naked eye on all US currency. In order to detect these features, the Signature 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.
  3. IR Infrared Feature Detection – Similar to UV, US currency contains hidden infrared features that can only be detected by infrared illumination and detection. The Signature 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 Signature cannot verify the correct features expected on a note, the unit will flag that currency as ‘SUSPECT’.
  • If sensors are dirty or damaged, the Signature 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.

The contact image sensor (CIS) of the unit is calibrated properly from the factory. With regular, basic use, the sensor’s sensitivity decreases which can lead to ID errors. To resolve this issue, the unit can be re-calibrated using the white calibration card that came with the unit.
For calibration procedure, a printable document is available in the links below for your corresponding software version.

If the Signature unit has a “DSort” mode please use this version of the document “Calibration Procedure (unit with DSort mode)”

If the Signature unit does not have “DSort” mode please use this version of the document “Calibration Procedure (unit w/o DSort mode) ”

  • One of the most common reasons for miscounting is improper loading of the currency to be counted. In most cases the Signature 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. Another example is FACE mode, where all notes which the same face up on the first note through the unit will be rejected.
  • Yes, the Kolibri Signature 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, undesired notes will be rejected into the upper reject pocket.
  • Yes, the Kolibri Signature uses advanced sensing to determine the denomination of the notes being scanned
  • The Signature uses a F2A250V 20mm Length by 5mm Diameter fuse above the AC power inlet (where the power cord inserts to the back of the unit.) 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.
  • Two rolls of paper are included in the packaging of the Signature. One roll has been installed into the built-in printer, while the other may be found in the packaging foam. The built in printer requires thermal paper. For best results, use 50 foot rolls.
    • Roll width: 2.25 inch (58mm)
    • Roll Diameter: 1.5 inch (40mm)
    • Speed 60mm/s
