Lexmark C762, C760 manual 8-29, Interfaces, 6 Input Buffer Sizes in Bytes

8-29

Interfaces

•The Ethernet 10/100BaseTX print server conforms to the IEEE 802.3 standard for 10BaseT networks using Category 3, 4, or 5 unshielded twisted- pair (UTP) cabling, and to the IEEE 802.3u Fast Ethernet standard for 100BaseTX networks using Category 5 UTP cabling.

For information on installing a print server in your printer, see your printer documentation.

You may also connect your printer to a LAN by using an external print server. Use one of the following:

•

•

Lexmark MarkNet print servers

IBM LAN Connection for Printers and Plotters (IBM 4033)

Note: Network capabilities are standard on some printer models. See your printer documentation for more information.

Input Buffer

Your printer has an input (link) buffer for each interface. The maximum size of the input buffer depends upon the amount of RAM memory installed. The input buffers serve the same purpose as a print spooler and can be allocated automatically by the printer. The size of the input buffer may be modified or disabled from the operator panel menus or through MarkVision Professional.

If NPAP is active on a port, two-thirds of the buffer memory is reserved for NPAP and one-third is set aside for the input buffer. If NPAP is not active, all the memory is available for the input buffer.

Table 8-8 shows the sizes automatically selected for the buffers when the buffer size is set to Auto in the menus.

Table 8-6: Input Buffer Sizes in Bytes

		Serial	Network
Memory Size	Parallel Buffer Size	Buffer Size	Buffer Size	LocalTalk	USB	Fax
2MB	12K	12K	12K	12K	12K	N/A
4MB	12K	12K	48K	12K	12K	350K
6MB	24K	12K	48K	24K	12K	350K

Note: MB represents 1,048,576 bytes. K represents 1024 bytes.

N/A means non-applicable.
