Canon fax machines manufactured since 2003 use a fax-image compression type named "Super G3." Essentially, super G3 allows for fax transmissions to be compressed while being transmitted allowing for faster speed while faxing. This increased speed engages the phone line for a shorter period of time, which lowers the expense of faxing; when you send a fax from a business line designated as a fax line, the longer the line is engaged, the more expensive it is. Super G3's compression ratio allows for the greatest amount of compression without sacrificing the quality of the faxed images.

Put the documents that you want to fax face down into the document feeder on the Canon fax machine. Depending on the fax machine model, you will be able to place up to 30 documents into the document feeder. Refer to your user's manual for specifications on the document feeder.

Dial the number of the fax machine where you want to send the fax. If dialing long distance, make sure you enter a "1" followed by the appropriate area code. Also, check with your IT staff to see if you need to dial a "9" before connecting to an outside line.

Press the green "Start" button. This will begin the scanning and faxing process. Once all the documents have been scanned, the Canon fax machine will dial the number of the receiving fax machine. If a connection is made, the fax transmission will begin. If the receiving fax line is busy, most Canon fax machines will store the documents into memory and will re-try to send the fax after a specified amount of time has elapsed.

Read the transmission report to make sure that all pages were transmitted. Canon configures many models of their machines to provide a transmission report after each fax is sent. Check the 1-page report to see that the recipient received the correct number of pages and that the result was successful.
