Manual Calibrations 4-15
Manual X Head
Registration
Precise positioning of each drop of ink is essential for optimal
print quality. This is possible only if you register all printheads in
the printhead assembly to each other in the X (along the length
of the platen) direction.
This is a two-part process:
• Print a registration pattern.
• Enter the X registration data for each head.
Note This is the manual version of AutoH2H Calibration
(see “Auto Calibrations” on page 4-6 for details).
1. Press the Calibrate key from the Front Page screen, then
press Manual Calibrations in the menu.
2. Press Manual X Head Registration in the menu.
The control panel asks whether you want to print a manual
head-to-head calibration page.
• If you have a calibration pattern from a recent print, you
can use it to calibrate the heads. Press

(Cancel) and
go to the next step.
• If you need to print a new calibration pattern, press

(Proceed). The printer prints a calibration page.
When the calibration page has printed, the control panel dis-
plays this prompt:
Take readings from left side of pattern.
3. Press the

key.
The control panel displays this message:
X Direction Registration
Head 2: +0
4. Examine the X direction pattern (in the left-hand group of
patterns) for the current head, and determine which pattern
of colored and black lines are the closest to perfectly
aligned.
