BASIC CONCEPTS

Non-imaged elements

Elements, such as text and graphics, may begin at the edge of the physical page on two sides, and off the physical page on the top and on the left side (except with 8.5 by 14 inch paper).

However, if any part of a printed element begins off the system page, no part of the element images.

·If a line of variable data begins off the system page, no part of the line prints.

·If a ruled line begins off the system page, no part of the ruled line prints.

·A ruled line near the edge of the system page must hold a position of at least one-half the line thickness inside the system page to print. For example, a bold line is eight dots thick and, therefore, it must hold a position of at least four dots inside the system page leading edge.

One common cause of print elements accidentally beginning off the system page is the improper use of the OUTPUT SHIFT command. This command shifts the entire page contents relative to the boundaries of the system page. When you enter a negative shift value (as is often the case for the back side of duplex pages), and that value exceeds the left margin, no text element prints. When using a negative value for the SHIFT command, be sure that it is less than the value of the left margin.

Imaging error messages

If any part of a print line originates off the system page, the following message displays:

OS6905 DATA ORIGIN OFF PAGE -- CHECK OUTPUT

This message line appears only once during a print job. It indicates that a print line origin problem exists within the form description, or that an excessive SHIFT value has been specified.

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 .05 inches (1.0 mm). The image can also slant or skew slightly by up to .05 inches (1.0 mm) in opposite directions, for a maximum skew of 0.1 inches (2.0 mm).

Note that the following figures are the same specifications which have been rotated to show portrait and landscape orientations. The shift and skew variances described here are within allowable specifications. However, 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 allowances for this condition.
