20 En Users in the U.S.A. Pre-Installation Requirements for Canon Facsimile Equipment A. Location Supply a suitable table, cabinet, or desk for the machine. See the e-Manual for specific dimensions and weight. B. Order Information 1. A single t elephone line (touch-tone or rotary) should be used. 2. Or der 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. Or der 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 NOTE 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, threewire 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. Connection of the Equipment This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA. On the rear panel of this equipment is a label that contains, among other information, a product identifier in the format US:AAAEQ##TXXXX. If requested, this number must be provided to the telephone company. The REN is used to determine the number of devices that may be connected to a telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the total RENs, contact the local telephone company. For products approved after July 23, 2001, the REN for this product is part of the product identifier that has the format US: AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point (e.g., 03 is a REN of 0.3). An FCC compliant telephone line cable and modular plug is provided with this equipment. This equipment is designed to be connected to the telephone network or premise wiring using a compatible modular jack that is Part 68 compliant. This equipment may not be used on coin service provided by the telephone company. Connection to party lines is subjected to state tariffs. In Case of Equipment Malfunction Should any malfunction occur which cannot be corrected by the procedures described in this guide or the e-Manual, disconnect the equipment from the telephone line cable and disconnect the power cord. The telephone line cable should not be reconnected or the power switch turned ON until the problem is completely resolved. Users should contact Canon Authorized Service Facilities for servicing of equipment, Information regarding Authorized Service Facility locations can be obtained by calling Canon Customer Care Center (1-800-OK-CANON). Rights of the Telephone Company If this equipment (imageCLASS MF419dw/MF416dw/MF414dw) causes harm to the telephone network, the telephone company may temporarily disconnect service. The telephone company also retains the right to make changes in facilities and services that may affect the operation of this equipment. When such changes are necessary, the telephone company is required to give adequate prior notice to the user. However, if advance notice is not possible, the telephone company will notify the customer as soon as possible. Also, the customer will be advised of his/her right to file a complaint with the FCC if he/she believes it is necessary.
