24 MX800 SERIES INSTALLATION GUIDE
Transaction Fails
to Process
The following are the corrective steps to be taken if the terminal does not process
the transaction.
There are several possible reasons why the terminal may not be operating
correctly or processing transactions. To check the most likely causes, follow the
steps below.
Step 1: Check the
magnetic card
reader
1 Make sure that you are swiping cards correctly with the MX800 Series
terminal. For the MX800 Series terminal reader, the black, magnetic stripe on
the card should face down and towards the screen.
2 Perform a test transaction using several different magnetic stripe cards to
ensure that the problem is not a defective card.
3 Process a transaction manually using the screen instead of the card reader. If
the manual transaction works, the problem may be a defect in the card
reader. Contact your VeriFone distributor or service provider.
4 If the manual transaction does not work, proceed to Step 3: Check the cable
connections.
Step 2: Check the
smart card reader
1 Make sure you are inserting the cards correctly with the MX800 Series
terminal smart card reader. The chip on the card should face down and
inward.
2 Perform a test transaction using several different smart cards to ensure that
the problem is not with the card.
3 Ensure any MSAM cards are correctly inserted and that the cardholders are
properly secured.
4 If the problem persists, contact your VeriFone distributor or service provider.
Step 3: Check the
cable connections
1 Ensure that all cables are correctly connected.
2 If cables are connected properly, check that the cable is in working order by
connecting a known good cable. If transactions process with this cable,
replace the defective cable.
3 If the problem persists, contact your local VeriFone representative for
assistance.
No Response
From the Stylus
The following are the corrective steps to be taken if the terminal does not respond
to the stylus inputs. (This procedure does not apply to the MX830 terminal without
touch screen.)
1 Check the documentation to ensure that the terminal supports this stylus.
2 Unplug the stylus that does not respond and connect a known working stylus.
3 If the problem persists, contact your local VeriFone representative for
assistance.
