Xerox 721P83071 manual Registration shift and skew

PRODUCT DIFFERENCES/USER CONSIDERATIONS

For A4 paper, the formula is:

Printer alignment in scan direction +69

If any part of an item begins more than this number of dots before the leading edge of the physical page, the item falls off the system page and does not print.

Registration shift and skew

The registration of a printed image can appear shifted or skewed on a page if the sheet of paper is misaligned as it enters the printer. Because of the design of the LPS feeder, the image registration on each page can vary slightly both horizontally and vertically by up to 0.65 mm. The image can also be slanted or skewed slightly by 3.97 milliradians. (Refer to figures 5-3 and 5-4, Landscape and portrait shift and skew.) Note that the following figures are the same specifications merely rotated to show portrait and landscape orientations. The shift and skew variances described here are within allowable specifications, but as this can affect the registration of variable data in preprinted forms and the placement of images close to the edge of the page, it is important to make allowance for this condition.

Figure 5-3 illustrates the landscape orientation shift and skew.
