Technical information

The printer has several user-installable options. You can add a duplex printing

unit, two additional 500-sheet feeders and cassettes, an external SCSI hard

disk, and an envelope cassette (the envelope cassette can replace any

500-sheet cassette). You can also increase the printer’s random-access

memory (RAM).

This chapter provides instructions for attaching an external SCSI hard disk

and increasing RAM.

Instructions for installing paper-handling options are included with each

option.

WARNING

When installing any of the options described in this chapter,

be sure the printer is turned off.
