Why Does a Money Counting Machine Give Errors? Common Faults and Fixes
Money counting machines are professional devices that make cash handling fast and accurate. But depending on how long a device has been in service, how well it has been maintained, the condition of the banknotes and the wear on its mechanical parts, faults do appear from time to time.
"Why does my money counting machine give errors?", "Why does it jam notes?" and "Why is it counting incorrectly?" are among the questions businesses ask most often once a device has been in use for a while.
Not every error means the device has broken down. Some problems come from the banknotes themselves or simply from a need for cleaning, while others do call for professional technical service.
1. Why Does a Money Counting Machine Miscount?
There can be several reasons behind an under- or over-count.
Among the most common:
- Dirty sensors
- Banknotes sticking together
- Heavily worn or folded notes
- A feeding mechanism that has drifted out of adjustment
- Rollers and rubbers worn down over time
- A device that has gone a long time without maintenance
Money counting machines track banknotes through sensors. Banknote dust and dirt building up inside the device over time can interfere with those systems.
If miscounting keeps recurring, the device may need more than cleaning — its mechanical and electronic components should be checked as well.
2. Why Does a Money Counting Machine Jam Banknotes?
Note jams are among the most frequent problems.
The cause is not always the device itself. Heavily folded, torn or stuck-together banknotes can create feeding problems on their own.
If it keeps happening, check:
- Feeding rubbers
- Separator parts
- Belts
- Rollers
- The banknote path
On heavily used machines in particular, rubber parts wear down over time and stop pulling notes through cleanly.
Rather than forcing a jammed note out while the device is running, it is safer to stop the machine and remove the note carefully.
3. Why Does It Pick Up Two Notes at Once?
If the machine pulls two or more banknotes from the hopper at the same time, something in the feeding system needs attention.
The main causes are:
- Banknotes sticking together
- Feeding adjustment being off
- Worn separator rubbers
- Dirty rollers
On older or heavily used machines, wear on mechanical parts makes double-feeding more common.
If the problem continues, the device may need calibration and mechanical maintenance.
4. Why Does It Give a Counterfeit Warning?
Advanced money counting machines do not only count notes — they also check a range of security features.
Depending on the model, a device may use:
- UV
- MG
- IR
- Image sensors
- CIS scanning technology
But a warning on a banknote does not always mean the note is definitely counterfeit.
Genuine notes that are very old, worn, soiled or physically damaged can sometimes fail the device's checks too.
Equally, dirty sensors or firmware that is not up to date for that banknote series can affect verification performance.
Suspect banknotes should always be checked separately.
5. Why Won't the Machine Take the Notes?
If you place banknotes in the hopper and the device does not start counting, there are a few possibilities:
- The hopper sensor may not be detecting the notes
- The banknotes may not be positioned correctly
- The feeding mechanism may be dirty
- Feeding rollers or rubbers may be worn
- The device's mechanical adjustment may have drifted
First make sure the notes are placed properly and that there is no foreign object in the hopper.
If the problem persists, it is better to have the device checked by technical service than to force it.
6. Why Do the Sensors Get Dirty?
Banknotes carry a considerable amount of dust and dirt from everyday use.
As thousands of notes pass through the device, that residue builds up on:
- The sensors
- The rollers
- The banknote path
Machines running in jewellers, exchange offices, retailers, bank branches and other cash-heavy businesses will need maintenance more often.
For that reason, money counting machine maintenance should not be seen as something you only do once the device has failed.
7. When Should Maintenance Be Done?
There is no single maintenance interval that applies to every device.
The need depends on:
- The number of notes counted daily
- How dusty the working environment is
- The device model
- The age of the device
- The condition of the banknotes
Checking heavily used professional machines regularly helps catch problems before they grow.
Maintenance can cover sensor cleaning, inspection of mechanical parts, necessary adjustments, calibration and part replacement where needed.
Should You Repair It Yourself?
Basic user cleaning and technical repair are two different things.
The simple cleaning steps described in the manufacturer's manual can be carried out by the user. But opening up the electronic or mechanical sections, altering sensor settings or replacing parts without the right knowledge can lead to bigger problems.
On advanced professional devices such as GLORY money counting machines, fault diagnosis and calibration are best left to technicians who know the device.
What to Look for in a Technical Service Provider
When choosing a service provider, the goal is not only to clear the fault but to diagnose it correctly.
It matters that the provider can:
- Identify the brand and model
- Access the right spare parts
- Diagnose both mechanical and electronic faults
- Carry out sensor work and calibration
- Test the device after maintenance
A wrong intervention may look like it solved the problem in the short term while causing different faults later.

Frequently Asked Questions
Why does my money counting machine keep giving errors?
Dirty sensors, worn banknotes, feeding problems, wear on mechanical parts, incorrect settings or an overdue service can all produce different error messages. The exact cause has to be established by inspecting the device.
Why does a money counting machine jam notes?
Folded or stuck-together banknotes, as well as worn rollers, feeding rubbers, belts or problems along the banknote path, can all cause jams.
What should I do if the machine is counting incorrectly?
Start by checking the condition of the banknotes and the cleanliness of the device. If the problem keeps recurring with different notes, have the device checked by technical service for maintenance and calibration.
Can the sensors be cleaned?
Yes. Banknote dust and dirt build up over time. But sensor cleaning must follow the manufacturer's instructions and be done without damaging the sensors.
If the machine flags a counterfeit, is the note definitely fake?
No. The warning means the note should be checked separately. A heavily worn or damaged banknote, dirty sensors or firmware that needs updating can all trigger the same alert.
