For example, if pattern +2 is the closest aligned, press the ￿ 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 ￿ (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 ￿ 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 ￿ or ￿ control panel keys repeatedly until the number next to the pattern that is closest to aligned perfectly is displayed.

17.Press ￿ (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.
