A difference in feed roller diameter from one printer to another causes a
media to advance by a different amount for a given rotation of a drive
shaft to which the feed roller is coupled. Such variation in advance
distance is a linefeed error. Mean linefeed error is determined and
corrected by printing a test plot having several areas. Each area is
formed of the same image pattern, but is printed at a different linefeed
error adjustment to compensate for mean linefeed error. The different
adjustments are prescribed and span a typical compensation range for a
given print engine model. The different adjustment factors cause banding
to occur in some areas. The user picks one of the test pattern areas
which has the highest print quality (i.e., least or no banding). The
linefeed adjustment factor corresponding to such area is used for normal
printing.
