Manual Calibrations 4-9
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.

Stitch pattern — First, allow the printer to print the following
number of swaths, depending on the mode you want to cali-
brate:
• 16 swaths in High Quality mode, or
• 8 swaths in Production mode
Next, press the

key to increase the advance until you see
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
tendency of the media advance to gradually decrease as the
size of the supply roll decreases.
You can pause and resume the printing of the stitch pattern.
34-inch (900 mm) calibration — prints a 34-inch (or 900
mm) test pattern so you can verify its length with an accurate
metal ruler. Cut the pattern from the media web, then mea-
