In the U.S. financial services industry, ATM are still the backbone connecting banks with customers. ATMs are so common nowadays that you will see them on every corner, and they play a huge part in keeping the cash flow moving.  

One thing that is just like all other machines, the ATM parts also wear out. Being a marvel of technology and running nonstop 24/7 makes them more prone to part damage.

Knowing which automated teller machine parts are most likely to fail—and understanding why—can save you serious time, money, and headaches. It also helps when you’re ordering replacements from trusted ATM parts suppliers like Dollar ATM Club.

Let’s break down the five most common parts of an ATM that tend to give out, what causes them to fail, and what you can actually do to prevent or minimize downtime.

​

1. The ATM Card Reader

It is one of the most critical parts of an ATM. An ATM card reader allows the machine to read the magnetic strip/chip on the user’s credit card/debit card and connect the ATM to a secure bank network. This is the brain of the ATM, and the machine is useless without it.

Reason to Fail

• The card slot is mostly clogged due to dirt and grime. This can play a part in picking of card or a failed transaction.
• The tempering and card skimming done by criminals by attaching fraud devices can damage the ATM card reader.
• Mechanical wear: When you’re talking thousands of card insertions, things get misaligned. Contacts wear down. It’s inevitable.
• The firmware of the ATM is another fragile area to look after; it gets out of sync and starts misreading the card data.

How to Prevent It:

• Keep the card reader slot as clean as possible. Use proper ATM supplies, especially manufacturer-approved cleaning cards, and do visual checks often. Get a proper vendor for your ATM parts that meets the needs with quick replacement, and keep the machine in action.

2. ATM Cassette

This is another main part that is known as the real powerhouse of an ATM. Each ATM cassette usually holds a specific bill denomination. The ATM Cassette and work more than any other part in an ATM.

Reason to Fail

• These parts of an ATM are usually responsible for grabbing money, and usually, with time, get worn out, which leads to jams and misfeeds on a constant basis.
• Sensors of both these parts can get compromised due to dust buildup. This will lead to false errors occurring and cause the wrong number of bills to come out.
• If the stacking of bills is not right in the ATM, then these parts can get damaged easily.
• If the ATM is placed in a humid area, then there is are high chances that its sensors can mess up.

How to Prevent It:

Schedule preventive maintenance for your automated teller machine parts, especially if you’re in a high-traffic location. Having access to quality components through Dollar ATM Club or another trusted supplier cuts your repair time way down.

3. ATM Receipt Printer

The ATM receipt printer is another part of the ATM that doesn’t get proper attention until it stops working. It plays an important part in customer satisfaction because they want proof against each transaction.  Among all the parts of an ATM, the printer probably takes the most abuse from constant use and environmental exposure.

Reasons to fail

• Paper jams and worn cutter blades are the usual suspects.
• Thermal head wear from all that heat and nonstop printing.
• Cheap paper rolls that shed residue all over the internal mechanisms.
• Loose cables or power supply issues that develop over time.

How to Prevent It:

Only use approved ATM supplies like quality thermal paper. The best thing to do is clean the parts on a regular basis and always keep spare ATM parts on hand for emergencies.  Partnering with Dollar ATM Club means you’ve always got access to reliable printer modules and backup parts.

4. The Power Supply Unit (PSU)

Every ATM depends on a stable power supply unit (PSU) to stay operational. This is a part that, if it fails, can shut down the ATM instantly. This can lead to stuck transactions and angry customers.

Reasons to Fail

• The major part is played by the voltage spike that fries the circuit board instantly.
• The buildup of dust that leads to overheating of the power supply unit of an ATM.
• Old capacitors that are worn out
• Moisture exposure to ATM Machines can cause power supply unit failure.

How to Prevent It:

You must install the surge protector, as it will allow you to keep the climate controlled inside the ATM. Check the voltage spike on a regular basis and get quality PSUs from trusted partners like Dollar ATM club.

​

5. The Keypad

The keypad gets the most direct contact from customers, which makes it one of the most stressed parts of an ATM. Over time, it degrades from constant physical interaction and environmental wear.

Reasons to fail

• The keypad gets damaged by heavy use, and the buttons stop responding.
• Loose wiring or bad connectors from repeated servicing and repairs.

How to Prevent It:

• Use weatherproof protective clean keypads regularly with non-corrosive cleaners. Always get replacement components from certified ATM parts suppliers that specialize in the types of ATMs in your network. Dollar ATM Club carries genuine keypads that work with multiple brands and models.

Understanding the Internal Parts of an ATM Machine

If you want to keep a well-maintained ATM Machine you must know how it’s built. Get to know the part played by each of the following ATM parts,

• Card reader
• ATM cassette
• Printer
• Power supply
• The keypad

Having a solid maintenance checklist—and a trusted source for replacement automated teller machine parts—is essential.
