Saving jobs

Jobs submitted electronically, either over the network or via media, can be saved.

•Both the “ripped” (Raster Image Processed) image and the job ticket will be saved.

•Ethernet license must be enabled in order to save job as PDF.

•Set up Instructions for Scan To File with NFS (Network File System) can be found in the Xerox Nuvera® Digital Production Systems Hints & Tips.

Productivity Impacts

There are several factors that can affect the performance of the system RIP speed when processing print jobs. The following is a list of common situations that negatively can impact throughput.

•The default print resolution of the system is 1200 dpi. 600 dpi printing may be adequate for your needs, so you can try setting that resolution to improve RIP performance of complex 1200 dpi jobs. 1200 dpi results in 4 times the internal image data of a comparable 600 dpi image that has to be transferred through the system. When the print resolution is changed from 1200 to 600 dpi, the stroke thickening value may also need to be changed from 1 to 0 to avoid excessive line thickening.

•It is common to embed logos and watermarks in submitted print files. These are typically bitmap images that when embedded in a print stream (such as PostScript) can take a long time to process. Note also that resolution selections (e.g. 600 dpi vs. 1200 dpi) can have a significant further impact to processing of these types of embedded images. Consider the design of documents and impacts to printing speed in such cases. There are methods available, through PostScript for example, to cache these embedded images, process them once, and retain them as a resource for application on each page without having to render and scale them for each page. Refer to your PostScript reference manuals and DocuSP® reference manuals for information about caching.

•Submission of multiple TIFF images simultaneously is a common application. There are several batch printing tools available on the market that enable this and most require the selection of a print driver for the target printer that these images files are submitted through. In these cases, the TIFF files are converted to a Printer Description Language (PDL, such as PostScript) by the batch tool by using the printer driver and then submitted to the printer, which in turn RIP that PDL and re-render the TIFF bitmap images back into bitmaps. This is an inefficient process and can significantly slow the machine down. Xerox Nuvera® includes a native TIFF interpreter and it can process TIFF files sent to it directly. Some of the batch tools on the market support a native TIFF submission capability. It may be referred to as a bypass mode or
