displacement.
After the adjustment, print the test pattern and check the two dotted lines. Perform the
adjustment until the two dotted lines become overlapped and deviation amount become
within the standard value.
Check whether the screw[C] which is rear side of Print head mount [D] is loose or not.
If it is loose, then tighten the screw [C] until the tip of the screw contacts the print head
mount [D]. When tip does not contact the print head mount [D], at this time you can
tighten the screw lightly, if you cannot tighten the screw lightly then you don’t need to
tighten it any more.
Especially when rotate the screw [B] counter-clockwise, it may need to tighten the screw
[C] a little until the tip of the screw contact the print head mount [D].
When tightening the screw [C], it is not necessary to tighten it too hard, it is just contact
to the print head mount [D].
After the adjustment, print the test pattern and check the two dotted lines.
If two dotted lines do not be overlapped, then rotate the screw [B] clockwise little bit more.
Perform the adjustment until the two dotted lines become overlapped and deviation
amount become within the standard value.
4.
Perform steps 3-1 to 3-3 for the cross lines printed above “C-3”
horizontal line printed under
“C-3”
to check the displacement between the second row and third row of the print heads. If
the two dotted lines do not overlap, adjust the print head (for the cyan nozzles) of the third row
