Turn each thumbwheel the appropriate number of clicks as indicated by the test page.

Send the file PHALIGN6.FLS (Printhead Mechanical Alignment Test Page) from the CD to the printer to
verify printhead alignment.

If the printhead alignment is within ±5 for both front and rear positions, then proceed to electronic
adjustment procedure. If not, repeat steps 12 through 15, until alignment is within ±5.
If you are replacing the black printhead, make sure on the test page that black is within ±5 and also within
±1 between the front and rear side. For example, if the rear looks like it is at +3, then the front should be
b2 and +4.
Note: When replacing the black printhead there is no Z value to reset. After the black printhead is
mechanically aligned to the magenta printhead, it will be necessary to electronically align the three color
printheads to the new black printhead.
