ATM Preventive Maintenance: What's Included and Why It Matters

← Back to Resources

Skipping ATM preventive maintenance is one of the most common — and most costly — mistakes branch operations teams make. What feels like a cost savings in the short term almost always leads to more expensive emergency calls, longer downtimes, and frustrated members.

Here's what a proper preventive maintenance visit should include, and what happens when it gets postponed.

What's Included in a Standard ATM PM Visit

• Cash dispenser cleaning and calibration — the #1 source of ATM jams and misfeed errors
• Card reader inspection and cleaning — EMV chip readers accumulate debris that causes transaction failures
• Receipt printer maintenance — cleaning the print head and checking paper path alignment
• Deposit module inspection — for ATMs with envelope or check deposit capabilities
• Diagnostic software run — catching error codes before they cause outages
• Physical security check — cabinet integrity, lock mechanisms, and anti-skimming review
• Software and firmware updates — where applicable

How Often Should Preventive Maintenance Happen?

For most ATMs in a financial institution environment, quarterly PM visits are the standard. High-traffic machines — drive-throughs, lobby machines at busy branches — may benefit from monthly visits. Low-traffic locations may be fine with semi-annual service.

What Gets Missed Without Regular PM

The failures we see most often at Ken Smith Inc. trace back to deferred maintenance:

• Cash dispenser jams from accumulated dust and worn rollers
• Card reader failures from dirty or corroded contacts
• Unexpected software errors from firmware that's months out of date
• Physical security vulnerabilities that go undetected until an incident

A $200 PM visit that prevents a $1,200 emergency call and 2 days of downtime is always the right investment.
