4-8 Manual Calibrations
10. Press B (Proceed).
The printer prints the calibration pattern you selected.
11. When the calibration page has printed, the control panel dis-
plays this prompt:
Bidi registration
Head 1: 0
12. Examine the BiDi Registration pattern for the current head,
and determine which pattern is the closest to perfectly
aligned.
Use a printer’s loupe to select the pattern, since the lines in
the patterns may be difficult to discern.
13 . P r e s s t h e C or p control panel keys repeatedly until the
number next to the pattern that is closest to aligned perfectly
is displayed.
For example, if pattern +2.0 is the closest aligned, press the
C key to change the display to:
HEAD-1 +2.0
If a printhead is extremely out of alignment, there may be
no pattern in alignment. Since the black vertical bars are
nominally 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. Alternatively, you can perform the BiDi Registration
repeatedly, which will move the head in smaller increments,
until the head is aligned.
14 . P r e s s B (Proceed).
The control panel message increments the head number by
one.
