distorted.
• Noise on the telephone line may cause distortion.
Have the other party try sending the document again.
• ECM mode (see page 50) will help prevent distortions
due to line noise. Note that ECM mode must be 
turned on in the other machine as well.
• 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.

Clean the scanning glass as explained on page 90.
