Solution
• Make sure that the reception mode is set to AUTO.
• Make sure that the wall socket is connected to the
TEL. LINE socket, and not the TEL. SET socket.
• Make sure that the document is loaded properly in
the feeder of the transmitting machine. Make a
copy or print a report to confirm the printing ability
of your machine.
• 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.
• 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.
• Any dirt or material on the scanning glass will
cause spots to appear on copies and transmitted
faxes. Clean the scanning glass as explained in
Chapter 8.
