B. Error message and Handling
If an error is detected while performing the "Non
Image Area Erase Check" mode, the following error
message will be displayed.
(1) Error message 1
Adjust for Moderate Brightness.
The Non-image area erase function may not
operate correctly with dark (density) origi-
nals.
Handling 1
When the non-image area erase function is not used
very frequently, or when copy originals that have a
dark background are not copied very frequently in
non-image area erase, the copier can be used in the
current installation location. However, when copy
originals that have a dark background are frequently
copied, install the copier in a location where less
external light gets in (darker) than the present loca-
tion, and check the non-image area erase check
mode again.
(2) Error message 2
Adjust for Extreme Brightness.
In many case, the non-image area erase
function will not operate correctly.
Handling 2
When the non-image area erase function is not
used very frequently, the copier can be used in
the current installation location. However, if the
non-image area erase function is frequently
used, install the copier in a location where less
external light gets in (darker) than the present
location, and check the non-image area erase
check mode again. At this time, when there is a
bright light source such as a fluorescent light
installed directly above the copier, reconsider the
installation location, or take some measures to
shield the light source and check the mode
again.
