3.5.2 ADS Control
When automatic image density sensing (ADS) is used, the exposure light
intensity varies depending on the background image density of the original.
The preceding table shows how the exposure light intensity changes
depending on the VOD/VSD ratio.
Use service program mode #10 to select the default ID setting. It can be set to
ADS or Manual ID level 4. The factory setting is ADS.
NOTE: If the exposure lamp cannot output sufficient light, service call
condition "E1" exists. However, copying is still possible. Refer to the
"SERVICE CALL CONDITIONS" table.
