4-12 Manual Calibrations
For example, if pattern +2 is the closest aligned, press the
C
key to change the display to:
X REG
HEAD-1 +2
If a printhead is extremely out of alignment, there may be
no pattern in alignment. Since the black vertical bars are
five pixels apart, you can add +5 or -5 to a pattern number
to shift the colored bars right or left by one black bar. Alter-
natively, you can repeatedly perform an X calibration, which
will move the head in smaller increments, until the head is
aligned.
12. Press
B (Proceed).
The control panel message increments the head number by
one.
13. Repeat steps 10 through 12 for each of the heads.
When you have entered registration values for all the heads,
the control panel displays this message:
Take readings from right side of pattern.
14. Press the
B key.
Y Direction Registration
Head 2: 0
X registration is complete. You are now ready to begin Y reg-
istration.
15. Examine the Y registration pattern (in the right-hand group
of patterns) for the current head, and determine which pat-
tern of colored and black lines are the closest to perfectly
aligned.
16. Press the
C or p control panel keys repeatedly until the
number next to the pattern that is closest to aligned perfectly
is displayed.
17. Press B (Proceed).
The control panel message increments the head number by
one.
18. Repeat steps 15 through 17 for each of the Y patterns.
When you have entered registration values for all of the pat-
terns, the control panel displays this message:
Registration successful.
