Starting the diagnostics

1.
Turn off the printer and the computer the diagnostics will be run from.
Connect the serial port of the computer to the special diagnostic, 5-pin
serial port of the printer; use the special serial cable adapter. (Pin 1 is
the left-most pin of the five pin connector, looking at the back of the
printer). Note the Pin 1 polarity mark (the brown wire) on the cable
adapter's connector.
In the case of a Macintosh, plug the serial cable from the printer into
the Mac's serial port marked "Modem".
2.
Push down the service mode dip-switch. (The switch is the left-most
of the four dip-switches on the rear panel of the printer, looking at the
back of the printer) The other switches should be up.

PowerBook, select AppleTalk Inactive from the file PowerBook control
strip menu.
