PRODUCT DIFFERENCES/USER CONSIDERATIONS5-18 XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDEXerox DocuPrint 180 LPS user considerationsThis section describes Xerox DocuPrint 180 LPS userconsiderations.Xerox DocuPrint 180 LPS edgemarkingTo ensure consistency across all Xerox LPS printers, the coordinatesystem used by all printers is identical. However, the area uponwhich an actual image may appear is limited. Because of this, datawhich starts near the edge of or off of the physical page may be lost.Edgemarking is the placement of marks at or near the edge of thephysical page. To accommodate edgemarking, the system pagemust be larger than the physical page.The Xerox DocuPrint 180 LPS edgemarking capability could belimited if the system page boundaries correspond to the sides of thephysical page of paper.If any part of a form element or variable data line is positioned off theleading edge of the system page (that is, the top edge of alandscape-oriented page or the left edge of a portrait-oriented page),the entire data element is not imaged. Refer to figure 5-1.• If a line of variable text begins off the leading edge of thesystem page, the entire line of text is not printed.• If a ruled line begins off the leading edge of the system page,the entire ruled line is not printed.• A line running parallel to the leading edge needs to bepositioned at least half the line thickness inside the leadingedge of the system page in order to be printed. For example, abold line is 8 dots thick and it must, therefore, be positioned atleast 4 dots inside the leading edge of the system page.• If any part of a signature or logo begins off the leading edge ofthe system page, the entire signature or logo is not printed.• One common cause of print elements accidentally beginning offthe system page is the improper use of the OUTPUT SHIFTcommand. This command is used to shift the entire contents ofa page relative to the boundaries of the system page. When anegative shift value is entered (as is often the case for the backside of duplex pages), and that value exceeds the left margin,no text elements will print. When using a negative value for theOUTPUT SHIFT command, be sure that it is less than the valueof the left margin.
