• Do not use your printer near water, or spill liquid of any kind
into it.
• Be certain that your power source matches the rating listed
on the back of the printer. If you are not sure, check with your
dealer or with your local power company.
• Your printer has an earthed, 3-pin plug as a safety feature,
and it will only fit into an earthed outlet. If you can not plug
it in, chances are that you have an older, non-earthed outlet;
contact an electrician to have it replaced with an earthed outlet.
Do not use an adapter to defeat the earthing.
• The outlet into which you plug your printer must remain easily
accessible at all times.
• To avoid damaging the power cable, do not put anything on it
or place it where it will be walked on. If the cable becomes
damaged or frayed, replace it immediately.
• If you are using an extension cable or power strip with the
printer, make sure that the total of the amperes required by all
the equipment on the extension is less than the extension’s
rating. Generally, the total ratings of all equipment plugged
into any one power line should not exceed 15 amperes. Don’t
exceed this unless you know that the power line your
equipment is plugged into has a rating above 15 amperes.

Connecting to the Computer
Note: You must supply a shielded cable for connecting
your printer to your computer.
1. When using the parallel interface cable, it needs
to be fitted with an in-line filter. If your cable
does not have an in-line filter, one has been
supplied for you in your accessory pack.
To fit, carefully open your in-line filter and close it over
the parallel interface cable, as close to the printer end
connector as possible, ensuring that the f ilter snaps closed.
2. Plug the interface cable into the parallel port (➊) and
secure it with the wire loops.

on single-thickness, continuous-form paper. For graphics or
charts, it's best to use the single-sheet path (top feed).
Note: If you ha ve paper in the paper path, be sure to
remove it before installing rear-feed paper.
