subtracted from the y_max value and the resulting value is then divided by process direction resolution in microns see step 108 for example if the process direction resolution is 1200 dpi then that is equivalent to 21 1667 microns per dot mpd or microns for short as there are 25 400 microns per inch thus the difference between y_avg n and y_max a value having units of microns in this example is divided by 21 1667 mpd similarly if the process direction resolution is 2400 dpi then that is equivalent to 10 5831 microns per dot mpd as there are 25 400 microns per inch thus the difference between y_avg n and y_max a value having units of microns in this example is divided by 10 5831 mpd next based on whether u201c line u201d compensation is used or u201c sub line u201d compensation is desired algorithm 100 results in the calculation of the amount of delay in scan lines for u201c line u201d compensation i e l n or alternatively the amount of delay in scan lines for u201c sub line u201d compensation i e l n and sl n see step 110 for u201c line u201d compensation l n is rounded to the nearest integer see step 112 while.
