4-12 Manual Head Registration
Use a printer’s loupe to select the pattern, since the lines in
the patterns may be difficult to discern otherwise.
10. Press the
b
or
c
control panel keys repeatedly until the
number next to the pattern that is closest to aligned perfectly
is displayed.
For example, if pattern +2 is the closest aligned, press the b
key to change the display to:
X REG
HEAD-1 +2
If a print head 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.

(Proceed).
The control panel message increments the head number by
one.
12. Repeat steps 9 through 11 for each of the heads.
When you have entered registration values for all the heads,
the control panel displays this message:
Y REG
HEAD-7 +0
X registration is complete. You are now ready to begin Y reg-
istration.
13. Examine the Y registration pattern for the current head, and
determine which pattern of colored and black lines are the
closest to perfectly aligned.

In this example, pattern “+1” is aligned the closest,
so “+1” would be entered.
