Reference Information
The correct light quantity value in ROS is normally 1024. If the value is decreased by 5%,
the light quantity decreases too.
Hence, entering the 5 stages of light quantity correction value by 5% is possible as below.
1024: Correct ROS Light Quantity Value
973: Light quantity value of 5% down
922: Light quantity value of 10% down
870: Light quantity value of 15% down
919: Light quantity value of 20% down
5. Take test patterns again with the Step 2 mode after changing.
6. Repeat Steps 3~5 until the density distribution that the client requests can be obtained.
7. Check the condition using the customer's samples. (Or ask the customer to print out the
sample from the same file and check the density on it.)
NOTE: Be careful in servicing because tone jump trouble may occur if the adjustment is cor-
rected drastically. The tone jump is a noticeable difference in the midstream of gradations
when the gradations etc. are printed out.
NOTE: When copying, borrow the document or sample that the clients has complained about.
