Blank Display
When the device display is blank:
•
If the device display is dark, tap the screen with your finger. If the unit was in
screen-saver mode, the screen will turn on when touched.
•
If the display does not show correct or readable information, then check all the
cable connections. If the problem persists, then contact your local Verifone
representative for assistance.
Transactions
Fail to Process
There are several possible reasons why the unit may not be processing
transactions. Use the following steps to troubleshoot failures.
Checking Magnetic
Card Reader
To check magnetic card reader:
1
Perform a test transaction using one or more different magnetic stripe cards to
ensure that the problem is not a defective card.
2
Ensure that you are swiping cards properly (see
).
3
Process a transaction manually using the keypad instead of the card reader. If
the manual transaction works, then the problem may be a defective card
reader.
4
Contact your local Verifone representative if the problem persists.
Checking Smart Card
Reader
To check smart card reader:
1
Perform a test transaction using several different smart cards to ensure the
problem is not a defective card.

).
3
Ensure that the SAM cards are properly inserted in the slots and are properly
secured.
