7.7 Adjusting the Ink Stream Position
¡When checking the ink stream position, wear protectors (safety goggles and
mask).
¡If the ink or makeup ink should enter your eyes or mouth, immediately flush
with warm or cold water and see a physician.
¡Before ejecting the ink, ensure that there is no person in the direction of
ejection. (The end of the print head must be placed in a beaker or the like.)
The ink stream adjustment procedure set forth below is to be performed after
nozzle or orifice plate replacement. Under normal conditions, the ink stream
needs no adjustment.
¡The ink stream position must be adjusted so that the ink ejected from the
nozzle is positioned at the center of the gutter.
¡Adjustments must be made in both the horizontal direction and vertical
direction.
