MNI 37XX REFERENCE MANUAL 119
2 Perform a test transaction using several different magnetic stripe cards to
ensure the problem is not a defective card.
3 Make sure you are swiping cards properly. With the Omni 37xx card reader,
the black, magnetic stripe on the card should face down, toward the keypad.
4 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.
Contact your VeriFone distributor or service provider.
5 If the manual transaction does not work, proceed to Step 3.
Step 2:
Check the smart card reader
1 Perform a test transaction using several different smart cards to ensure the
problem is not a defective card.
2 Make sure you are inserting the cards properly. With the Omni 37xx smart
card reader, the chip on the card should face down and inward.
3 Ensure the MSAM cards are properly inserted and the SAM holders are
properly secured as described in Install/Replace MSAM Cards.
4 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.
Contact your VeriFone distributor or service provider.
5 If the manual transaction does not work, proceed to Step 3.
Step 3:
Check the telephone line
1 Connect to a working telephone and check for a dial tone. If there is no dial
tone, replace the Telco cable.
2 If the problem appears to be with the telephone line, check with the party you
are trying to call to see if their system is operational. If they are not
experiencing difficulties with their line, contact the telephone company and
have your line checked.
3 If the telephone line works, contact your local VeriFone representative for
assistance.
Keypad Does Not
Respond
1 Check the display panel. If it displays the wrong character or nothing at all
when you press a key, follow the steps outlined in Terminal Display Does Not
Show Correct or Readable Information.
2 If pressing a function key does not perform the expected action, refer to the
documentation for that application to be sure you are entering data correctly.
3 Perform a local diagnostic test of the keyboard in system mode (refer to
System Mode Menu 5).
4 If the problem persists, contact your local VeriFone representative for
assistance.
Cleaning and
Care
For normal dirt, use a clean cloth slightly dampened with water and a drop or two
mild soap. For stubborn stains, use alcohol or an alcohol-based cleaner.
