6-14 Memory For minimum acceptable job buffering performance, the hard disk should be able to read and write files at a sustained rate of 600Kb/sec. The Lexmark hard disk option supports this requirement. Some advantages of job buffering include: • The printer accepts print jobs more quickly. • The printer accepts print jobs from all ports as long as the disk is not filled. • The printer continues to print even after the host computer, network connection, or printer server goes down. • Buffered jobs print when power is restored after a printer power loss. • The printer manages print jobs from multiple sources. Keep in mind that job buffering may also: • Slow system performance. • Restrict the amount of memory available on the disk for other uses. • Increase the time required for a printer reset or recovery after a power loss. • Reprint jobs after a power-on reset (POR). Creating a Partition Note: Creating a job buffering partition is only required for the Lexmark C720 and J110 printer models. Before job buffering is enabled for a port, you must allocate a portion of the disk for job buffering functions. The minimum size for a job buffering partition is 10 percent of the disk storage space. When a new partition is created, the entire disk is formatted and all resources previously downloaded to the disk are lost. Once a partition is defined, this disk space is reserved for job buffering. Enabling Job Buffering Note: Creating a job buffering partition is only required for the Lexmark C720 and J110 printer models. Once a partition is allocated, job buffering to a disk may be enabled for each active link port. You can enable job buffering from the operator panel menus, if available, or through MarkVision Professional. You cannot enable a port before the partition is
