Manual Calibrations 4-21
Jet Status Lines This option prints the Manual Jet Mapping test pattern (see Fig.
4-4 on page 4-17) that shows which jets are working, and which
jets are out, but does not run the Manual Jet Mapping calibration
(see “Manual Jet Mapping” on page 4-16 for information).
Media Feed Calibration This calibration allows you to calibrate the accuracy of the media
advance. Inaccurate media advance can result in blank spaces
between print swaths (too much advance) or overlapping swaths
(too little advance). The Media Wizard stores this value by media
type, and displays a media feed number (MFN), which you can
record for subsequent entry.
The media feed number enables you to quickly specify a known
good media feed setting without recalibration. For example, you
could keep a list of media feed numbers by media type, or by
media type and full, half, and nearly empty supply rolls.
Tip You can also adjust the media advance while a print
job is printing. Repeatedly press the increase
advance or decrease advance button shown on the
control panel to eliminate blank spaces or overlap
between print swaths. When you do this, the media
feed number displayed on the control panel
changes accordingly.

blank spaces between swaths.
Finally, press the ) key to decrease the advance until the
blank spaces are eliminated, but avoid dark lines between
swaths (which indicate overlap). This method allows for the
