What Is Polling?8-28Using PollingWhat Is Polling?Polling means one fax machine calls another fax machine and requests that theother fax machine send a document that it is holding. Unlike normal sending andreceiving, in polling, the receiver always calls the sender. This is called polling toreceive a document. The sender sends the document in response to a pollingrequest by a telephone call from the receiver.NOTEYour machine can be set up to function in both roles. Your machine can poll to receive adocument, or it can be polled to send a document that it is holding.Before You Use Polling ReceivingBefore you try to set up polling, note the following points:• In one operation you can poll several machines. You can dial up to 210 telephonenumbers, and poll those machines to receive documents that they are holding.• You can poll a machine for a document at any time, but you may find it more usefulto set your machine for polling other machines at specified times throughout theday. (See “Polling to Receive at a Preset Time,” on p. 8-5.)• You must know if the other fax machine is holding the document under both asubaddress and password, or only a subaddress or password. You must alsoknow the subaddress and password so you can enter them on your machine. Ifyou do not know the subaddress or password, contact the other party.• If the other party’s documents are registered for polling without a subaddress orpassword, you can still perform polling receiving.• If the other party’s fax machine does not support ITU-T subaddress/passwordtransactions, you can ask them to set the polling ID to ‘255’ or ‘1111 1111’ binarywhen the other party’s fax machine is a Canon fax machine.
