Problems and Solutions Reception and copying problems Problem Solution The fax machine doesn't receive documents automatically. • Make sure that the reception mode is set to AUTO. If you subscribe to a distinctive ring service, make sure that the Distinctive Ring function is set to the correct ring pattern. If you do not subscribe to a distinctive ring service, make sure that Distinctive Ring is set to OFF SETTING. (See Distinctive Ring in Chapter 5.) The received document is faint. • Ask the other party to send higher contrast documents. If the contrast is still too low, your fax machine may need service. Make a copy or print a report to check your machine's printing ability. • The toner cartridge may need replacement. The printed image appears dirty and/or the paper jams frequently. • Have a service technician clean the print compartment. The power is on, but no reception takes place. • Make sure that the wall jack is connected to the TEL. LINE jack, and not the TEL. SET jack. Received images are distorted. • If ECM mode (Option Setting 9) is turned off, noise on the telephone line may cause distortion. Have the other party try sending the document again. • If the other machine has ECM mode, make sure this feature is turned on in both fax machines (see Option Setting 9). • Make a copy or print a report on your fax machine. If the copy or report is also distorted, your fax machine may need service. • The drum cartridge may be damaged. Try a new drum cartridge. • The fusing unit and transfer roller may need to be replaced during the life of the machine if print quality begins to deteriorate. This must be done by a service technician. 126
