[. . . ] Any excess memory is allocated among all memory clients. » Note: The printer does not allow you to choose features that do not work with the amount of memory currently installed. Using this option does not change the media size. It just ensures that you have enough memory allocated to the appropriate clients to print on the requested media size. .

Additional Technical Information 5-15 Memory The following table lists, for your information, the minimum number of KB that must be devoted to the frame buffer for all media size and resolution combinations: Media Minimum Frame Buffer Size (in KB) 300 x 300 dpi Letter Legal A4 Envelopes Executive B5 ISO Postcard 960 1236 996 468 776 736 236 600 x 600 dpi 3832 4936 3960 1852 3100 2984 932 Display List Also known as K Mem Display, this client stores compressed representations, or blocks, of the pages to be printed. It takes approximately 1 compressed block for a normal 8. 5" x 11" (215. 9 mm x 279. 4 mm) text page, 4 compressed blocks for an 8. 5" x 11" (215. 9 mm x 279. 4 mm) page that includes some graphics, and as many as 500 compressed blocks for an extremely complex page. Many pages of compressed blocks (R1 blocks) belonging to multiple print jobs can be stored at the same time in the display list. If enough memory is allocated to this memory client, a page can always be ready to print as soon as another page has been imaged to the print engine. The amount of memory required for each R1 block is printer specific. The QMS 1060 Print System takes approximately 64 KB of memory from the display list for each compressed block. However, if a page includes raster image data (for example, TIFF or bitmap data), each compressed block will require much more memory. 5-16 QMS 1060 Print System Reference Memory Increasing the amount of memory in this client may improve printing throughput and minimize slowdowns due to collating or printing complex pages. If not enough memory is allocated to this client, memory is taken from the excess memory client to complete a print job. PostScript Font Cache Also known as K Mem PS Fonts and Font Cache, this memory client stores bitmapped representations of previously scaled PostScript fonts. This process reduces the number of times a font must be converted from outline form to bitmap form. Printing pages that have characters already stored in the font cache is immensely faster than printing characters not yet in the font cache. As the font cache memory fills, the printer makes room for new bitmapped characters by erasing those that have been in the cache longest without being used. By increasing the memory allocated to this client, the printer can store more characters and spend less time erasing and replacing characters in the cache. This client has a limit to the maximum point size it will store. Normally, you don't need to change this memory client unless you use a large number of fonts at various point sizes. If you do, you may allocate additional memory to this client to improve printer performance. There's no specific formula to use in figuring the amount of memory required by the font cache, but after a certain point, large font caches cause the printer to take longer to print than smaller font caches because of the search time through the cache. The recommended font cache size is in the following ranges: n n 128-256 KB for 300x300 dpi printing 256-512 KB for 600x600 dpi printing If the font cache is "really big" performance is slowed because all the fonts have to be searched. You should experiment to see what font cache size works best for you. Additional Technical Information 5-17 Memory PS Heap Also known as K Mem PS Heap, PostScript VM, and Virtual Memory, this client holds downloaded fonts, PostScript operators, and forms. Inefficiently coded PostScript jobs can consume an unlimited amount of virtual memory or leave objects in the PostScript heap after the print jobs are completed, leading to virtual memory errors. If not enough memory is allocated to the PS heap, the job cannot print. [. . . ] SIMMs use less board space and are more compact than more conventional memory-mounting hardware. SIO Simultaneous Interface Operation. The capability of printing to all three of the printer's concurrently active ports rather than being restricted to one. See also concurrent interfaces. Soft Fonts Fonts created or stored on disk. They can be transferred to the printer's memory and remain available for use until the printer is turned off. [. . . ]
