IQ-10 Thin Line Interruption
Thin line interruption
Figure 1 j0rt30002
[Cause]
Depending on the structure of the line, the interruption may stand out by the position of the screen.
[Procedure]
1. Check with the customer whether the [Thin Line interruption] is outside the permissible range or not.
2. Check to see if there is no problem with the Banding/Starvation level.
[Corrective action]
1. Switch the Driver UI Screen to [Definition Priority].
[Thin line interruption] will not occur easily as the number of lines go high.
• Select [Advanced Setting] > [Screen], and change to [Tone Priority] -> [Fineness Priority].

NOTE: Check the image and use since Banding Starvation will slightly worsen as secondary
failure.
