Virtual Memory Support

Your printer supports virtual memory capabilities for the spooling

buffer and the display list clients when a hard disk is installed and

disk swapping is enabled.

Once you have a hard disk installed on your printer, it has virtual

memory capabilities for specific memory clients, extending the

amount of memory available for certain supported features. Your

printer supports spooling overflow, which is an extension of the K

Mem for Spool memory client, collation, and it has a hard disk.

You can dedicate part of that disk for collation overflow or as an

extension of the display list memory client.

Spooling Overflow

The spool overflow option is located in the Administration / Disk

Operations menu. This option specifies the maximum space

reserved for spooling overflow on the hard disk.

When a print job is sent to your printer, a portion of that job is stored

in the spooling buffer (K Mem for Spool) while the rest of the job

is being printed. If all the memory in the spooling buffer is being

used and the Spool Overflow option is enabled, the printer stores

the “overflow” from the spooling buffer in a reserved area of the

hard disk. Even if you have a hard disk, you should allocate as much

RAM to the spool buffer as possible for increased throughput.

Reserving a 10-20 MB portion of the hard disk for spooling

overflow works well for most printing environments. If too much

of the disk is dedicated to spooling, the printer’s performance may

actually be hindered because the printer tries to fill the overflow

space before passing the job to the processor.
