Preinstallation Requirements for Canon Facsimile Equipment
A. Location
Supply a suitable table, cabinet, or desk for the machine. See p. 13‑2 for specific dimensions
and weight.
B. Order Information
1. A single telephone line (touch‑tone or rotary) should be used.
2. Order an RJ11‑C telephone wall jack (USOC), which should be installed by the telephone
company. If the RJ11‑C wall jack is not present, telephone/facsimile operation is not
possible.
3. Order a normal business line from your telephone company’s business representative. The
line should be a regular voice grade line or an equivalent one. Use one line per unit.
DDD (Direct Distance Dial) line
‑or‑
IDDD (International Direct Distance Dial) line if you communicate overseas
Canon recommends an individual line following industry standards, i.e., 2,500 (touch‑tone) or 500
(rotary/pulse dial) telephones. A dedicated extension off a PBX (Private Branch eXchange) unit without
“Call Waiting” can be used with your facsimile unit. Key telephone systems are not recommended because
they send nonstandard signals to individual telephones for ringing and special codes, which may cause a
facsimile error.
C. Power Requirements
The machine 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 that often interferes with communications equipment and the
sending and receiving of documents.
