Transactions Fail to Process

There are several possible reasons why the unit may not be processing transactions. Use the following steps to troubleshoot failures.

• Check Magnetic Card Reader
  • Perform a test transaction using one or more different magnetic stripe cards to ensure the problem is not a defective card.
  • Ensure that you are swiping cards properly (see Magnetic Stripe Card Reader Use).
  • Process a transaction manually using the keypad instead of the card reader. If the manual transaction works, the problem may be a defective card reader.
• Check Smart Card Reader
  • Perform a test transaction using several different smart cards to ensure the problem is not a defective card.
  • Ensure that the card is inserted correctly (see Magnetic Stripe Card Reader Use).
  • Ensure the MSAM cards are properly inserted in the slots and are properly secured (see MSAM/uSD Cards).

e285 Terminal

Device Does not Start/Does not Display Correct Readable Information

If the device does not start:

• Ensure that the device is plugged into a dedicated power source. An icon at the top of the display indicates the battery charge level if it is getting a charge from the cord. The battery charge level needs to be high enough for the terminal to turn on.
• Verify all the cable connections including the proper insertion of the power cable connector.
• If the problem persists, please contact your platform 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 shows incorrect or unreadable information, inspect all cable connections. In case the problem persists, reach out to your local Verifone representative for assistance.
• If the device display is white, this occur when the reader is below a 20% battery charge. It is always recommended to make sure your E285 reader is above a 20% battery charge when using it to conduct transactions to ensure optimal performance. To remedy this issue, fully charge your E285 reader, and start a new transaction attempt.

Keypad Does Not Respond

If the keypad does not respond properly:

• Examine the device display. If it displays the wrong character or nothing at all when you press a key, follow the steps outlined in Transactions Fail to Process.
• Refer to the user documentation for that application if using a function key does not produce the anticipated outcome, to ensure accurate data entry.
• If the problem persists, please contact your platform for assistance..

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 the Magnetic Card Reader:
  • Perform a transaction using one or more distinct magnetic stripe cards to rule out the possibility of a faulty card.
  • Ensure that you are swiping cards correctly.
  • 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.
  • If the problem persists, please contact your platform for assistance..
• Checking the Smart Card Reader:
  • Execute a transaction using various smart cards to eliminate the possibility of a faulty card.
  • Verify that the card is inserted correctly.
  • Ensure the SAM cards are appropriately inserted into the designated slots and are securely in place (refer to Installing Micro SIM and or SAM Cards).
• Checking the Contactless Reader:
  Make sure there are no obstructions between the contactless logo and the card, ensuring a clear path between the contactless reader and the actual card for a seamless transaction.

Can't Connect to Mobile Hotspot

The E285 reader can only communicate using 2.4ghz frequency band WiFi networks. Some mobile hotspots default to 5ghz. This can be resolved by changing the settings in your mobile device.
