TROUBLESHOOTING
This section explains problems frequently encountered when using the document filing function. If you experience
any difficulty, refer to the following table. For information on general machine problems, printer problems, fax
problems, and network scanner problems, please see the troubleshooting sections of the appropriate manuals.
Problem Check Cause and solution
A saved file has
disappeared.
Was the file called up and then printed by
touching the [PRINT AND DELETE THE
DATA] key?
A file that is printed using the [PRINT AND
DELETE THE DATA] key is automatically
deleted after being printed. To print a file
without deleting it, use the [PRINT AND
SAVE THE DATA] key.
A file cannot be
deleted.
Is the file's attribute set to [PROTECT]? A file cannot be deleted when its attribute is
set to [PROTECT]. Change the attribute to
[SHARING] and then delete the file.
A file's attribute
cannot be set to
[CONFIDENTIAL].
Is the file in the main or custom folder? A file in the Quick File folder cannot be set to
[CONFIDENTIAL]. Move the file to a
different folder or set it to [PROTECT].
A file's attribute
cannot be changed
to [PROTECT].
Is the file set to [CONFIDENTIAL]? A file cannot be simultaneously set to
[CONFIDENTIAL] and [PROTECT]. If set to
[CONFIDENTIAL], use [PROPERTY
CHANGE] (page 7-21) to change the
attribute to [PROTECT].
A name in the Quick
File folder is cut off.
Was the name programmed in the advanced
transmission settings?
If the name was programmed in the
advanced transmission settings before the
file was saved in the Quick File folder, that
name will be used. However, if the name is
longer than the maximum name length of the
Quick File folder (30 characters), the excess
characters will be discarded.
Resolution settings
are not possible.
Was the file saved at low resolution? A saved file cannot be transmitted at a
resolution higher than the resolution at
which it was saved.
A file name cannot be
stored or changed.
Have you entered prohibited characters in
the file name?
Certain characters (symbols) cannot be
used in file names. See "ENTERING
CHARACTERS" (entering numbers and
symbols) on page 7-29.
A custom folder
name cannot be
stored or changed.
Have you entered prohibited characters in
the folder name?
Certain characters (symbols) cannot be
used in folder names. See "ENTERING
CHARACTERS" (entering numbers and
symbols) on page 7-29.
The printing speed
of a saved file is
slow.
The file was saved using one of the following
resolution settings:
●
200 x 200 dpi resolution.
●
STANDARD (200 x 100 dpi) or FINE (200
x 200 dpi)
When a file is saved using one of the
resolutions setting at left, the printing speed
will be slower than when other resolution
settings are used.
Black dots appear
when a file that was
saved with the
document filing
function is printed.
Was the file saved at other than the following
resolutions?
●
600 x 600 dpi
●
600 x 600 dpi and HALF TONE
To check the resolution of the saved file, touch
the [DETAIL] key in step 5 on page 7-16.
This problem can be alleviated by setting the
resolution to 600x600dpi when saving a file
with scan save.
The problem can be further alleviated by
selecting HALF TONE after setting the
resolution to 600x600dpi, as light images
will be printed lightly.
