1.4 Optional Equipment
1.4 Optional Equipment
The following DEClaser 3200 equipment is optional and can be installed by the
customer:
• When the PostScript option is installed, the printer becomes a DEClaser
3250. The PostScript option consists of the PDL board, a coprocessor single
in-line module (SIM), and three 2-Mb SIMs.
The PostScript description language (PDL) code resides on the PDL board
which plugs into a socket on the video control board. Once installed, you
can select it from the PROTOCOL feature of the Set Up menu as described
in Section 2.4. Section E.3 describes the features, values, and submenus
that appear when you select the postscript protocol.
• The coprocessor board mounts in a SIM socket J10 on the video control
board. It provides processing power for the PostScript interpreter. Without
a functional coprocessor, the printer will fail to operate in PostScript mode.
• The 2-Mb and ½-Mb expansion memory SIMs mount in sockets on the
video control board. Each video control board comes with a ½-Mb SIM
installed in socket J15. See Table 5–2 for socket allocation information.
• The LCIT holds up to 1500 sheets of paper. It feeds the sheets into the
bypass slot and receives power and command signals from the DC control
board through an 8-pin modular type connector. See Chapter 11 for a full
description.
• A number of cartridges are available that plug into the font cartridge slots
on the front panel. The read-only memory (ROM) in these cartridges are
tested by power-up diagnostics on the video control board.
