Supply a suitable table, cabinet, or desk. See p. 11-1 for the machine’s weight and 
dimensions.

1. Only a single line, touch-tone or rotary telephone set is to be used.

2. Order an RJ11-C modular jack (USOC code), which should be installed by the 

telephone company. If the RJ11-C jack is not present, installation cannot occur.

3. Order a normal business line from your telephone company’s business representative. 

The line should be a regular voice grade line or the equivalent.

Use one line per machine.

DDD (DIRECT DISTANCE DIAL) LINE

-or-

IDDD (INTERNATIONAL DIRECT DISTANCE DIAL) LINE IF YOU COMMUNICATE 
OVERSEAS

Canon recommends an individual line following industry standards, e.g. the 2500 (Touch Tone) or 
500 (Rotary/Pulse Dial) telephones. A dedicated extension off a PBX machine without “Call Waiting” 
can be used with the machine. Key telephone systems are not recommended because they send 
non-standard signals to individual telephones for ringing and special codes, which may cause a fax 
error.

This equipment should be connected to a standard 120-volt AC, three-wire grounded 
outlet only. Do not connect this machine to an outlet or power line shared with other 
appliances that cause “electrical noise.” Air conditioners, electric typewriters, copiers, and 
machines of this sort generate electrical noise which often interferes with communications 
equipment and the sending and receiving of documents.
