Ingenico Opus: Display Screen Cleaning Procedure - Solar... | terminalfaults.org

Technical Background:

The Opus display is a capacitive touchscreen. Surface contaminants can interfere with capacitive coupling, causing touch unresponsiveness or inaccurate readings. Cleaning solutions with high conductivity can cause temporary malfunctions. Static discharge (ESD) from cleaning cloths, especially in dry environments, may affect touchscreen functionality.

Symptoms:

Display screen requires cleaning due to visible smudges, fingerprints, or residue affecting readability.

Possible Causes:

Accumulation of oils and dirt from user interaction.
Use of improper cleaning solutions containing harsh chemicals or abrasives.
Residue from cleaning solutions affecting touch sensitivity.
Static discharge during cleaning, particularly in low-humidity environments.
Scratches or damage to the display surface from abrasive materials.
Environmental factors such as dust and airborne particles.

Solution:

1

Power down the Ingenico Opus terminal by safely disconnecting the power cable from the rear of the device.
2

Use a clean, lint-free microfiber cloth.
3

Lightly dampen the microfiber cloth with distilled water. Avoid oversaturation.
4

Gently wipe the display screen in a circular motion to remove smudges and fingerprints.
5

For stubborn residue, use a commercially available screen cleaner specifically designed for electronic devices. Apply the cleaner sparingly to the cloth, not directly to the screen.
6

Allow the screen to air dry completely before reconnecting the power cable.
7

Power on the terminal and verify touchscreen functionality.

Safety Warning:

Always disconnect the power supply before cleaning to avoid electrical shock. Avoid spraying liquids directly onto the device. Ensure the device is completely dry before reconnecting to the power supply. Do not use excessive force when cleaning the screen, as this may cause damage. Avoid using abrasive cleaners or solvents.

Prevention:

Implement a regular cleaning schedule (e.g., daily or weekly) based on usage and environmental conditions. Place the device in a location with minimal dust exposure. Educate staff on proper cleaning techniques.

Expert Tip:

In areas with high static electricity, use an anti-static spray on the microfiber cloth before cleaning. This can help prevent ESD and potential touchscreen issues. A can of compressed air can be used to remove loose debris before wiping, minimizing scratches.

Frequently Asked Questions

•What type of cleaning solution is recommended?

Use a screen cleaner specifically designed for electronic devices. Isopropyl alcohol (70%) diluted with distilled water can be used sparingly.

•How often should the display be cleaned?

Clean the display screen daily or weekly, depending on usage and environmental conditions. More frequent cleaning may be necessary in high-traffic areas.

•What should I do if the touchscreen is not responding after cleaning?

Ensure the screen is completely dry. If the issue persists, power cycle the device by disconnecting and reconnecting the power cable. If problems persist, contact technical support.
