(4) Using the output film, check the sensitivity.
N CHECK N
Make sure that the S value on the film is held within the following range.
ST: 140 ≤ S value ≤ 260
HR: 84 ≤ S value ≤ 156
(5) Make sure that there is no density unbalance in the image of the output film.
N CHECK N
Make sure that there is no density unbalance in the main scan direction.
If any density unbalance is found, compare the films outputted from two IPs of the same
size to isolate its probable cause.
• If the density unbalance positions in the main scan direction are the same
➮ The culprit is an improper mounting of the light-collecting guide assembly.
IP in normal orientation (first)
• If the density unbalance positions in the main scan direction are different
➮ The exposure-related component(s) may be a probable cause.
