1. A method for measuring disparities and for compensating for differences between a user plane and a device plane, the method comprising:
- printing a test pattern on one side of a tray alignment page;
measuring said test pattern; and
calculating parameters by using said test pattern measurements, said parameters used in compensating functions to transform incoming coordinates from said user plane into coordinates for said device plane.

12. A method for performing tray alignment for at least one tray, said tray associated with a media type and associated with an output device, to correct for outputting inadequacies in said output device, the method comprising:
-
specifying, using an input means associated with said output device, said tray to be aligned and said media type;
outputting an alignment calibration page from said output device, using said tray and said media type;
determining alignment calibration values using said alignment calibration page and entering said values in said input means; and
applying said calibration values.

31. A tray alignment calibration page used for calibrating tray alignment, comprising:
-
three scales, entitled A, B, and C, respectively, wherein said A and C scales indicate an amount of shift along a y-axis required for performing tray alignment, said A and C scales having a midpoint used as a default tray alignment setting, and scale B indicates an amount of shift along an x-axis required for performing tray alignment, said B scale having a midpoint used as a default tray alignment setting; and
means for determining where a vertical fold falls on said B scale upon folding said alignment calibration page in half vertically;
means for determining where a horizontal fold falls on said A scale and on said C scale, upon folding said alignment calibration page in half horizontally;
A, B, and C text boxes, respectively, for writing said determined values from said A, B, and C scales, respectively;
a bottom side of said alignment calibration page used during repeating said preceding operations for duplexing; and
means for transferring said written values into said dialog box;
wherein said dialog box comprises a default button, whereby upon selection, default values for all trays replace currently stored tray alignment calibration values. - View Dependent Claims (32, 33, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

34. An apparatus for performing tray alignment for at least one tray, said tray associated with a media type and associated with an output device, to correct for outputting inadequacies in said output device, comprising:
-
means for specifying, using an input means associated with said output device, said tray to be aligned and said media type;
means for outputting an alignment calibration page from said output device, using said tray and said media type;
means for determining alignment calibration values using said alignment calibration page and entering said values in said input means; and
means for applying said calibration values, said means associated with said output device and said input means.
