All Epson interfaces have the Epson name printed on them. If the
board has an identification code printed on it, it is a four-digit
number beginning with 8 and should correspond to one of the
numbers listed in the table above.
Also Coax and Twinax interfaces are available from third party
vendors. These interfaces allow connectivity to mainframes and
minicomputers and emulation of IBM printers. The Coax
(EP-Connect) is available from Avatar Corporation [phone], and
the Twinax (I-08300) is available from I-O Corporation [phone].
Installation
1. Unplug the printer and remove the printer cover and paper guide.
WARNING: High voltages are present inside the printer
when the power is on. Do not attempt to remove the
upper case unless the printer is turned off and the power
cord is unplugged. Also, try not to touch contacts on the
circuit board of the printer because many of the
components can be destroyed by the static electricity
present in your body.
Do not change the settings of any DIP switches on the
main board.
