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)
