Charging the Battery
1
Make sure printer is off and it is
connected to AC power outlet with AC
adapter and power cord.
2
Press main switch and hold it down for a
few seconds until green BATTERY indicator
stays lit. This puts printer in Charge mode,
which completely discharges battery and
then charges it. Green BATTERY indicator
stays lit until discharging is completed;
then it blinks until charging is completed.
When finished, printer turns itself off.
Tips on Using the Battery
Charging battery after it has been
completely discharged takes about 70
minutes.
When you run printer on battery power,
it can print approximately 30-35 pages
on a full charge.
Darker prints discharge battery faster
than lighter prints do. Use density dial to
adjust lightness and darkness.
Printer's protective vinyl case has sleeve on
inside for extra battery. With two batteries,
you can print twice as many pages before
you have to charge batteries.
Self-Test Sheet: To print sheet, set switch 3
to ON. Turn printer on. Insert paper. When
done, turn printer off. Set switch 3 to OFF.
Clean Print Head: To clean print head with
cleaning cloth, set switch 4 to ON. Turn
printer on. Press main switch quickly again to
start platen roller. Insert cloth with rough
black side towards rear of printer. When
done, turn printer off. Set switch 4 to OFF.

Refresh battery: While in Charge mode, push
once and hold for several seconds until
green BATTERY indicator starts to blink.
Power off during Charge or Refresh mode:
Push twice quickly.
Density Dial
Density dial is on side of printer closest to
operation panel. Larger numbers make
prints darker. Smaller numbers make prints
lighter.
NOTE: Your Ni-Cd battery will last much longer
and carry a greater charge if it is always
completely discharged prior to charging.
Refreshing the Battery
You may refresh a seasoned battery
occasionally when you don't have time to
completely discharge and charge it.
Refreshing a battery "tops off" the charge
without first discharging battery.
CAUTION: This procedure is not recommended,
particularly with a new battery, as it may reduce
the battery's life and its ability to carry a charge.
