5-14 Set the Printhead and Camera Height

The carriage must be lowered below the height of the gauge

and then raised. If the carriage is simply lowered on top of

the gauge, the carriage will tend to settle lower during print-

ing, changing the head height and invalidating the calibra-

tions.

Caution

Do not allow any part of the gauge to touch the

printheads, and do not leave the gauge on the

platen after setting the head height. If the gauge is

allowed to touch or strike the printheads, the print-

heads could be damaged permanently and require

replacement.

9. Turn the head height adjustment screw clockwise, just until

the end of the gauge slides under the carriage.

10. Remove the gauge and repeat steps 7 through 9 at the other

side of the carriage.

11. Verify the heights at both sides of the carriage and adjust if

necessary.
