• If you cannot find the item that you are looking for in the above table of contents, see "GENERAL PROBLEMS" (page
8-41).
• If you are unable to solve a problem using the solutions in this manual, switch off the [POWER] key ( ) and the
main power switch. Wait at least 10 seconds, and then switch on the main power switch and the [POWER] key ( )
in that order.
Caution:
When the LINE indicator is lit or the DATA indicator is lit or blinking, do not switch off the main power switch
or unplug the power plug. This may damage the hard drive or cause the data being stored or received to be
lost.
Problem Point to check Solution
Copying does not take
place.
Have functions been disabled by the
administrator?
When user authentication is enabled, the functions that
you can use may be restricted in your user settings.
Check with your administrator.
Auto selection of the
colour mode does not
take place.
Are you using one of the following types
of originals?
Black & White is not selected
• Are there colours or colouring in the
paper?
Colour is not selected
• The colour in the original is very light.
• The colour in the original is very dark,
almost black.
• Is only a very small area of the
original coloured?
When the colour mode is set to "Auto", the machine
detects whether the original is black and white or colour
when the [COLOUR START] key is pressed. However,
when an original similar to one of those at left is used,
automatic detection may not give the correct result. In
this event, specify the colour mode manually.
