PRINTER HARDWARE COMPONENTS
The SCSI is an 8-bit parallel interface standard used to connect
peripheral devices, such as rigid disks, floppy disks, and tape
drives, to computer systems.
The 4890 controller has a SCSI that connects all the standard and
optional peripheral devices available for the 4890. Because the
4890 is an all-SCSI system, you can boot from any device as long
as the boot files are on the media for the device.
Graphic video generator
The optional graphic video generator (GVG) option with a
standard 32-Mb or optional 256-Mb of graphic memory enables
the printer to receive digitized graphic data. GVG accepts
graphic data encoded according to the Xerox .IMG and .RES
standards.
Note: To accept and print graphic data input, the LPS must be
equipped with the GVG option.
Font memory expansion
The 4890 has as a standard feature 32-Mb of font memory, which
can be expanded to 128 Mb.
High-capacity feeder
The high-capacity feeder (HCF) provides two additional feeder
trays. The capacity of each tray is 1000 sheets of 20 pound or 80
gsm paper. Refer to figure 2-10.
