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.
