6.5.11 Problems due to inappropriate ink stream position to gutter
>
If the ink stream does not enter the center of gutter, the following problems may
occur:
(1) The ink stream hits the inner wall of gutter inlet and “splash” occurs. This will
dirty the gutter, causing either Ink Drop Charge Too High or No Ink Drop
Charge.
(2) Ink accumulates on outer circumference of gutter, then the character quality
will degrade. (The lower dots of printing to be missing.)
(3) The ink drops charged for auto phase detection are slightly deflected by the
deflecting field. Therefore, if the ink stream position is bent to the positive
electrode side from the center of gutter and A is larger than 2B as shown in
figure below, the ink drops may hit the end surface of gutter.
>
Check the ink stream position, and perform adjustment making sure that the ink
stream enters the center of gutter.
