4-4 Manual Calibrations
Media Feed Calibration This calibration allows you to calibrate the accuracy of the
media feed process. You perform this calibration when loading
media, or later if prints requiring very accurate length (for exam-
ple, output that will be tiled) are found to be the wrong length.
To perform this procedure, it is helpful to have a magnifying
glass or printer’s loupe to examine the test patterns.
◆ Before performing a Media Feed calibration, print the Prime
Bars and clean the ink jets to get the maximum number of
jets working.
◆ After performing a Media Feed calibration, run AutoSet.
1. If you will be performing this calibration with a new roll of
media, advance the media to the floor, back it up to the
platen, and remove the supply loop (see page 2-13).
This will remove the advance error that would be introduced
by the tighter winding at the beginning of a new roll of
media.

If you press Cancel, to go step 13.
When you press Proceed, you can choose between the fol-
lowing calibrations:
◆ 34-Inch (900 mm) Calibration — prints two reference
marks along the direction of media feed; measure the
distance between the marks to determine advance
accuracy.
◆ 12-Inch (305 mm) Calibration — same as previous cali-
bration, uses less media but may be less accurate.
