2-3. Handling Notes
(1) Install the printer near an easily accessible socket-outlet.
(2) Place the unit on a flat and stable surface for operation.
(3) Do not connect the AC Power Plug to the same outlet used for other noise
generating devices (large motors, etc.).
(4) Be careful not to drop paper clips, pins and other foreign objects into the
unit.
(5) Wipe off dirt with a soft cloth soaked in alcohol or benzine. Do not use
Lacquer thinner, Trichlorethelene or Ketone solvents because they may
damage plastic parts.
(6) Use a soft brush, etc. for cleaning the printer mechanism and PCB.
(7) Keep hands out of printer while power is on.
(8) Do not attempt to print when there is no ink ribbon or paper in the unit. The
print head life could be severly reduced.
(9) Ifthepaperisfastened tightly to the roll, the paper may not detach from the
roll when the end is reached.
If this happens, the no paper detection function and paper feed will not
operate.
(10) Always keep the printer cover attached when printing to prevent paper
jams, noise, and other problems.
(11) Always turn the power off before opening the printer cover. (e.g. When
renewing a ink ribbon)
