LPS operating system
The 4635 System Software consists of the Xerox OSS, System
User Interface (UI) Software, User Interface Dialog, and the
Printer Software. The OSS is the primary software; however,
each software type working in conjunction controls and monitors
the operation of your 4635 LPS.

the operation of your 4635 LPS.
The LPS OSS, like any other operating system, is a set of
programs which allow the printing system to manage its own
resources. Xerox distributes new versions of the 4635 OSS on 9-
track, 18-track cartridge, or quarter-inch cartridge tape. The OSS
tape contains:

The process by which the OSS is installed, upgraded, or modified
is called system generation or sysgen. There are three types of
sysgens that can be performed: mini, update, or full.

•
In a mini sysgen, an existing operating system is modified in
a way that does not require new system file input or
patching. For example, an existing feature is deactivated or
reactivated, or a specification is changed that is independent
of the operating system files.
