Restricting polling access (polling security)
If you wish to prevent unauthorized fax machines from polling your machine, enable the polling security function.
When this function is enabled, polling permission will only be granted if the fax number of the polling machine (as
programmed in that machine) matches one of the fax numbers that you have programmed in your machine as
passcode numbers. Up to 10 fax numbers can be programmed as passcode numbers.
To turn on the polling security function and program passcode numbers, see "PASSCODE NUMBER SETTING" on
page 104.
There are two types of polling security functions. Polling is permitted when the numbers of either type match.
• If you do not use the polling security function, the document will be sent to any fax machine that polls you.
• When using the polling memory function with polling security enabled, the fax number of the polling
machine(s) must be programmed in your machine. The polling machine must also have its sender's number
programmed.
