How to Troubleshoot Common Cash Handling Equipment Issues: Solution Guide

Jan 27, 2026

Introduction

In the fast-paced business operation scenario, cash handling equipment is an indispensable and important tool in daily transactions. Bill counter, mixed denomination CIS money counter, counterfeit detector, UV detector, coin counter and sorter, and money binding machine not only simplify cash processing procedures and reduce manual errors, but also help businesses resist the risk of counterfeit currency.

However, once these core devices fail, for example, the bill counter machine may get stuck, the counterfeit money detector may misjudge the authenticity of bills, and the coin counter sorter may make errors in denomination sorting, it may lead to business stagnation, which not only consumes time and money, but also affects customer satisfaction. But as long as you master some basic knowledge and troubleshooting skills, you can quickly solve problems and restore normal operation of the equipment. This guide will sort out the common malfunctions of various cash processing equipment and provide step-by-step solutions for enterprises of different sizes.

 

Bill Counter: Fixing the Most Frequent Jams and Counting Errors

Bill Counter

The bill counter is the main force in the cash processing process, and its failures are mostly caused by daily wear and tear or improper operation. The three most common problems encountered by business owners are cash jams, inaccurate counting, and unresponsive display screens.

Bill counter machine often get stuck due to the rapid insertion of bills or the accumulation of dust and debris inside. To solve the problem, first unplug the power to prevent electric shock, then open the cash tray and gently remove the stuck bills, and finally wipe them with a dry cloth to avoid subsequent jamming. The inaccurate counting is caused by dirty sensors or uneven stacking of bills. When solving the problem, wipe the optical sensor with a lens cloth to ensure that the bills are stacked flat and the equipment is placed horizontally. The lack of response on the display screen is mainly due to power or wiring issues. Checking the power cord connection, power off and restarting the device, or replacing the battery can eliminate most faults. If there is still no response, contact the manufacturer for repair.

 

Mixed Denomination CIS Money Counter: Resolving Recognition and Counting Flaws

Mixed Denomination CIS Money Counter

The mixed denomination CIS money counter uses advanced contact image sensor (CIS) technology to simultaneously recognize and count bills of different denominations, making it a powerful tool for enterprises to improve efficiency. However, due to its precise technology, many malfunctions are related to sensor performance or software systems.

The denomination recognition error is mainly caused by dirty sensors, untimely software updates, or poor quality of paper currency. When solving the problem, first clean the CIS sensor with a fiber cloth, then check if there are any software updates and installations, and be sure to pick out damaged bills before counting. Missed counting is usually caused by slow or unstable cash feeding speed. Adjusting the speed gear of the equipment and tightening the screws appropriately to increase grip can improve the situation.

 

Counterfeit Detector & UV Detector: Fixing False Alerts and Detection Failures

Counterfeit DetectorUV Detector

The counterfeit detector and UV detector are the first line of defense for cash anti-counterfeiting, and their accuracy is crucial. Common faults include false alarms, missed detections, and UV lamp malfunctions.

False alarms from the counterfeit money detector are often caused by high sensitivity settings or dirty UV detector tubes. To solve the problem, it is necessary to clean the UV lamp and adjust the sensitivity appropriately to reduce misjudgment. Missed detection of counterfeit currency is usually caused by outdated detection software or aging and burning UV lamps. When the brightness of the UV lamp tube becomes dim or cannot be lit, it should be replaced immediately, and the currency detector software should be regularly updated to ensure the recognition of the latest counterfeit methods. When using, the bills should be placed flat under a UV lamp for comprehensive scanning to avoid folding and obscuring anti-counterfeiting features. The UV lamp cannot light up. First, check the connection between the power cord and the socket, and then replace the burnt out lamp tube. Portable models also need to check the battery to eliminate poor contact issues.

 

Coin Counter & Sorter: Fixing Jams and Sorting Mistakes

Coin Counter & Sorter

The coin counter and sorter saves several hours of manual counting time for enterprises that handle large quantities of coins. Its main faults are card currency and sorting errors. Coin counter sorters often get stuck in the sorting track due to foreign objects such as paper clips and dust.

To solve the problem, first turn off the power, open the machine and use tweezers to remove debris, then use a small brush to clean the sorting track. At the same time, check if the exits are blocked to ensure that each exit is accurately aligned with the coin storage box. Sorting errors are usually caused by inaccurate calibration of size sensors. When solving the problem, first press the calibration button to reset the sensor. If the fault persists, replace the original factory certified sorting tray accessories. The counting deviation is mainly caused by uneven coin dispensing speed. Slowly dispensing coins at a uniform speed and promptly emptying overflowing storage boxes can avoid counting errors.

 

Money Binding Machine: Fixing Punching and Binding Problems

Money Binding Machine

The money binding machine makes cash more organized and stored safely. Common faults include punching failure, loose bundling, and paper tape jamming.

Punching failure is often caused by clogging or wear and dullness of the punching needle. You can use a fine needle to clean the paper scraps inside the pinhole after power failure, and replace the punching needle. Note that most models can only handle 100-200 bills at a time, do not overload. Loose bundling is caused by low tension of the paper tape or dirty heating elements. You can adjust the tension knob on the side of the device and wipe the residual adhesive residue on the heating element with a dry cloth to ensure that the paper tape is tightly sealed. Paper tape jamming is often caused by paper tape damage or installation misalignment. You can remove the stuck paper tape and cut off the damaged part. When reinstalling, ensure that the paper tape is aligned with the card slot and only use the paper tape specifications recommended by the manufacturer, which can effectively avoid jamming.

 

Emergency Quick Fixes for Urgent Situations

During peak business hours and other time sensitive situations, the following temporary methods can be used to maintain operations:

After the bill counter machine or coin counter and sorter gets stuck, clean up debris and manually place each note and coin into the machine one by one;

When the counterfeit money detector malfunctions, use a spare ultraviolet flashlight for basic authenticity verification.

Please note that this is only a short-term response. After the peak period, it is necessary to complete regular troubleshooting and maintenance in a timely manner to avoid repeated malfunctions.
