Epson LQ-300 User Manual page 17

If you use an extension cord, make sure that the total of the
ampere ratings on the products plugged into the extension
cord does not exceed the extension cord's ampere rating.
Also, make sure that the total of all products plugged into
the wall outlet does not exceed 15 amperes.
Never push objects of any kind into your printer because
they may touch dangerous voltage points or short out parts
that could result in a risk of fire or electric shock.
Except as specifically explained in the user's manual, do not
attempt to repair the printer yourself. This could expose
you to dangerous voltage points or other risks. Refer all
servicing in those compartments to service personnel.
Unplug the printer from the wall outlet and have it
repaired by a qualified service person under the following
conditions:
When the power cord or plug is damaged or frayed
If liquid has been spilled into it
If it has been exposed to rain or water
If it does not operate normally when the operating
instructions are followed. Adjust only those controls that
are covered by the operating instructions since improper
adjustment of other controls may result in damage and
will often require extensive work by a qualified technician
to restore the printer to normal operation.
If it has been dropped or the cabinet has been damaged
If it exhibits a distinct change in performance, indicating a
need for service
