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.

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.
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.
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.
3 Press main switch and hold it down for a few seconds until green BATTERY indicator starts to blink. This bypasses discharging process and puts printer in Refresh mode, which charges battery. Green BATTERY indicator 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.

Auto-off Timer: Printer must be powered from its battery. When switch 8 is OFF, printer turns itself off after 60 seconds if it is not receiving data (unless there is data in printer buffer).
Inserting Paper
1 Use both hands to hold paper straight while you insert it into printer’s paper input slot. Make sure bottom edge of paper is parallel to feed roller.
Make sure smooth, coated side of paper faces the back of printer.
2 Press paper gently and evenly into printer’s input slot until roller pulls it into starting position, then let go.
If paper is skewed after printer pulls it into starting position, do as follows.
◆ If printer does not start to print immediately, open release cover as far back as it will go. Pull paper out and reinsert it. Close cover.
◆ If printer does start to print, wait for page to be printed and then reprint page if necessary.
TIP: If you insert paper before you start print job, you will have time to adjust paper if it is skewed after printer pulls it into starting position.
