Problems and Solutions

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.
