For a 8 head machine
Step 1 :
Start the self-diagnostic function.
Notes :
¾ Refer to “Self-Diagnosis Function”
Step 2 :
Select "Adj:HeadSlant".
Step 3 :
Print "Slant" pattern.
If dotted lines on pattern CW and CCW are not a straight line, which you can check with a
magnifying glass (enlargement of at least 10), please go to step 4.
Notes :
When the printing pattern is printed, you will only see lines, and no notifications of ink
channels. The head sequence shown below.
8 head model: 3A, 3B, 1A, 1B, 2A, 2B, 4A, 4B, 5A, 5B, 6A, 6B, 7A, 7B, 8A, 8B
Step 4 :
Loosen the screw (with one turn) fixing the head stationary plate.
Step 5 :
Make adjustments until amount of CW and CCW offset are identical.
Notes :
¾ In theory, the alignment of CW and CCW should be identical. But in practice, it is
almost impossible to become a perfect alignment. When there is a slight difference
between CW and CCW, be sure the heads are well seated.
¾ In case you only print uni directional, adjust the CW till it is perfect aligned.
¾ In case you print bi-directional, and CW and CCW cannot be aligned more perfectly.
Divide the fault equally.
