B. Problems and their countermeasures
When a problem is detected by checking the non-image area erase check, an error number is displayed as
shown below.
(1) Error 1
Countermeasure - 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 instal-
lation 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 location, and check the non-image
area erase check mode again.
(2) Error 2
Countermeasure - 2
When the non-image area erase function is not used very frequently, the copier can be used in the current instal-
lation 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.
