• The input value is outside the range.
Cause: A value exceeding the range allowed for an input item was input.
User response: Input a value inside the allowed range. Refer to the input item or the
image scanner specification for the range.
• The input value is not acceptable.
Cause: A value exceeding the range allowed for an input item was input.
User response: Input a value inside the allowed range. Refer to [Help] of the item or
the User's Guide for the correct range.
• This file cannot be removed because it is specified in other side.
Cause: An attempt was made to remove a file using the dither pattern or
gamma download pattern file setting dialog. However, the file is
being used for the other side (front side if back side or back side if
front side).
User response: Before removing the file, change the setting of the other side and then
remove.
• The initial value contains an invalid value. The default value is set.
Cause: A value outside the specified range, or invalid text was found in the
initial-value data file (the specific item involved is indicated by
Entry=XXXXX). If the file has been modified, the setting value for
the item may be wrong. If the file has not been rewritten, the file may
have been damaged.
User response: The value is set to a standard value. Be sure to check the hard disk
(chkdsk/scandsk) and check for computer viruses regularly.
• The value is higher than the maximum scanning size. Either the resolution value or the
scanning area has to be reduced.
Cause: A value exceeding the data capacity of the scanner was specified. As
the resolution is increased, the amount of data to be scanned also
increases.
User response: Decrease the resolution or reduce the size of the scan area.
