This bulletin provides information on how to interface Epson laser printers with an

Epson PostScript’ Card to an Apple Macintosh2 using Apple LocalTalk3 and the
Bridgeport4 by Extended Systems.

Connecting a printer to an Apple Macintosh can be difficult if the printer does not
have an AppleTalk interface. The Epson Action Laser II and EPL-8000 laser
printers with the Epson PostScript Card installed do not have built-in AppleTalk
interfaces and as such can be difficult to connect to an AppleTalk network.

Extended Systems has a solution to this problem. It is the Bridgeport 2679B. This
printer sharing device allows you to connect a PostScript printer to an AppleTalk
network and two DOS-based PCs. The Bridgeport has an AppleTalk port that
allows connection to either a stand-alone Macintosh or to an AppleTalk network via
Apple LocalTalk. This device also has a serial and a parallel port for connecting
two DOS-based PCs. The Bridgeport will monitor each of the input ports and route
data that it receives to the printer.

The Bridgeport 2697B was tested from an AppleTalk network to an Action Laser II,
an EPL-8000 with the Epson PostScript Card, and to an Epson EPL-7500. All three

installations worked flawlessly and the printed output was exactly as expected. This
device requires that the Apple LaserWriter? driver Version 5.2 or above be installed
on the network.

The manufacturer suggested retail price of the Extended Systems’ Bridgeport is
$495.005Se below for Extended Systems’ address and telephone numbers.

Subject: Action Laser II PCU Handling Tips

EPSON

Date: 6/5/92
Page(s): 1 of 1

This bulletin contains information on Photo Conductor Unit (PCU) handling.

Cause

Most PCU failures are due to improper handling. The oil from human hands will
contaminate the Optical Photo Conductor (OPC) belt and causes the OPC layer to
separate from the base layer. Initially it will bubble then later it will tear. The OPC
belt is also sensitive to light and other materials.

Preventive Action

To prevent the above mentioned problem, the size of the protective sheet that
wraps around the OPC belt was increased.

The second action taken was the installation of a caution sticker on the PCU.

Installation Precautions

PSB No: P-0088
Originator: VB

Anyone handling the PCU needs to:

Follow the directions in the User’s Guide.

Be extra careful not to touch the OPC belt when installing or removing the PCU

from the Action Laser II.

When setting the PCU down, be sure the surface is flat and clean.

Always cover the PCU and protect it from bright light.
