Troubleshooting Guidelines

This page compiles common instances of malfunctions that may arise during the operation of your device, along with the corresponding steps to address them. The troubleshooting guidelines outlined in the subsequent sections are incorporated to facilitate the effective installation and configuration of the device. Should you encounter challenges in operating your unit, please refer to these troubleshooting examples. If the issue persists despite following the provided guidelines or if the problem is not covered, kindly reach out to your local Verifone representative for further assistance.

The device is equipped with tamper-evident labels and does not contain any user-serviceable parts. It is crucial not to attempt to disassemble the unit under any circumstances. Only perform adjustments or repairs explicitly outlined in this guide. For any other services, please contact your local Verifone service provider. Utilizing services from unauthorized parties may potentially void any existing warranty.

All units require the use of a power supply. Only use a Verifone-supplied power pack. Using an incorrectly rated power supply may damage the unit or cause it to malfunction. Ensure that the power supply used to power the unit matches the specified requirements on the back of the unit (refer to Specifications for detailed power supply specifications) before troubleshooting. If not, obtain the appropriately rated power supply before continuing with troubleshooting.

Toutes les unités nécessitent l'utilisation d'une alimentation. Utilisez uniquement un bloc d'alimentation fourni par Verifone. L'utilisation d'une alimentation mal calibrée peut endommager l'appareil ou l'empêcher de fonctionner correctement. Assurez-vous que l'alimentation électrique utilisée pour alimenter l'unité correspond aux exigences spécifiées à l'arrière de l'unité (voir Spécifications pour les spécifications détaillées de l'alimentation électrique) avant le dépannage. Dans le cas contraire, procurez-vous une alimentation électrique appropriée avant de poursuivre le dépannage.

Device Does not Start/Does not Display Correct Readable Information

If the device does not start:

• Ensure that the device is plugged in to a dedicated power source.
• Verify all the cable connections including the proper insertion of the power cable connector.
• If the problem persists, reach out to your local Verifone representative for assistance.

Blank Display

When the device display is blank:

• If the device display appears dark, tap the screen using the stylus. If the unit is in screen-saver mode, touch the screen to activate.
• If the display does shows incorrect or unreadable information, inspect all cable connections. In case the problem persists, reach out to your local Verifone representative for assistance.

Battery Does Not Charge

The e280 device battery must initially be charged fully to ensure proper operation.

• Allow the e280 device to remain connected to the power pack for eight hours to ensure the battery receives a full charge.
• Li-ion batteries are not affected by shallow charging. Furthermore, when the device has no external power source or battery, the coin cell battery provides power to the security circuit.
• Disconnecting and unplugging the device power pack reduces the life of the coin cell battery, which does not recharge and must be replaced if drained.
• Conserve battery power by turning the e280 device off when not in use. Do not let the battery charge fall below 10% for an extended period of time as this may permanently diminish the battery capacity. Recharge the battery by attaching the USB end of the power pack to the device and plugging the other end of the power pack into a wall outlet.
• The e280 device automatically shuts down when the battery reaches the critically low charge state.
• Charge the device once a week even if the device is not in use.

Transactions Fail to Process

Multiple factors could be causing the unit to fail in processing transactions. Utilize the following steps to troubleshoot and identify the root of the failures.

Checking Magnetic Card Reader

To check the magnetic card reader:

1. Perform a transaction using one or more distinct magnetic stripe cards to rule out the possibility of a faulty card.
2. Ensure that you are swiping cards correctly (see Using the Magnetic Card Reader).
3. Process a transaction manually using the keypad instead of the card reader. If the manual transaction is successful and the issue persists with the card reader, it may indicate a problem with the card reader itself.
4. If the problem persists, reach out to your local Verifone representative.
