Suggestions
Try changing your resolution to Fine or S.Fine. Make a copy to check your
machine's scanner operation. If the copy quality is not good, clean the scanner.
(See Cleaning the scanner glass on page 151.)
There is probably temporary noise or static on the line. Try sending the fax again.
If you are sending a PC Fax message and get 'RESULT:ERROR' on the
Transmission Verification Report, your machine may be out of memory. To free up
extra memory, you can turn off fax storage (see Turning off Remote Fax Options
on page 68), print fax messages in memory (see Printing a fax from the memory
on page 49) or cancel a delayed fax or polling job (see Checking and cancelling
waiting jobs on page 43). If the problem continues, ask the telephone company to
check your telephone line.
If you often get transmission errors due to possible interference on the telephone
line, try changing the Compatibility setting to Basic(for VoIP). (See
Telephone line interference on page 136.)
Make sure you are loading the document properly. (See Loading documents
on page 22)
Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip. (See Cleaning the scanner glass on page 151.)
