3.11.5 Set Background Level
The background level is an established threshold used to help measure the reflective ability of a
scanned document. This threshold can change if the scanner lamp, CCD, or the ballast is replaced;
therefore this mode should be used to reset the threshold when these items are changed.
The Set Background Level mode allows the level to be set without erasing memory contents.
Note: The background seal at the inside of the scanner cover should be cleaned prior to setting the
background level to ensure an accurate reading.
1. Press <Setting>, <*>, <0>, <9>, then select [Background level].
2. Press [Start] to start the background level setting.
After the background level setting, the machine goes back to the standby mode.
