Lexmark Printer manual Creating a Partition, Enabling Job Buffering

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

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

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 allocated. When buffering is enabled from the printer operator panel, a power-on reset (POR) automatically occurs. If buffering is enabled through MarkVision Professional, you must perform a full power-on reset before job buffering can occur.
