TROUBLESHOOTING GUIDELINES
Terminal Does Not Dial Out
156 VX 520 REFERENCE GUIDE
Terminal Does
Not Dial Out
If the terminal does not dial out:
Check the telephone line connections.
Check that the telephone line is working by plugging it into a working
telephone and listening for a dial tone.
Replace the telephone cable that connects the terminal with a cable you know
is working correctly.
If the problem persists, contact your local VeriFone service provider.
Printer Paper
Jam
If paper jams inside the printer:
Open the paper roll cover.
Remove the damaged paper from the paper roll and clear the feed
mechanism.
Install a roll of printer paper, as described in Installing the Paper Roll in the
Printer.
If the problem persists, it may be due to poor paper quality. Install a new
roll of higher-quality paper.
Keypad Does
Not Respond
If the keypad does not respond properly:
Check the terminal 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.
If pressing a function key does not perform the expected action, refer to the
user documentation for that application to ensure you are entering data
correctly.
If the problem persists, contact your local VeriFone representative.
Peripheral
Device Does Not
Work
If any peripheral device (PIN Pad or smart card reader) does not work properly:
Check the power cord connection to the peripheral device.
Check that the device connected to the proper port has power and is
functioning properly. If possible, perform a self-test on the device in question.
The cable connecting the optional device to the terminal serial port may be
defective. Try a different serial cable. See Connecting Optional Devices.
If the problem persists, contact your local VeriFone representative.
WARNING
Poor-quality paper may jam the printer. To order high-quality VeriFone paper,
refer to Accessories and Documentation.
