POWER switch — This switch activates the power when it is in the ON position. Push this switch on and you will hear the print head prepare itself for printing.

ON LINE switch — This switch allows you to switch back and forth from on-line to off-linestatus. When the printer is on-line, it is ready to receive data from the computer. When the printer is off-line, it is not ready.

ON LINE light — The red light, located above the ON LINE switch, indicates whether the printer is on or off line. The light glows red when the printer is on-line, and when the light is off, the printer is off-line. If you turn the power ON without any paper in the printer, the ONLINE light will not glow, even if you press the ON-LINE switch.

The ON LINE light blinks when the motor has locked or the battery is low. When the light is blinking, first check to see if the paper or ribbon cassette is stuck. If either of these is stuck, turn the power off and correct the problem. The ribbon cassette should return to the starting position on the left side when you turn the power back on. If you can not find anything wrong with the printer, the blinking light is indicating that your battery is low. Turn the power OFF and plug in the AC adapter as described later in this chapter.

PAPER FEED switch — This switch allows you to automatically advance the paper one line at a time. You can only activate this switch when the printer is off-line. Tap this switch to advance the paper one line at a time. Hold the switch down to advance the paper several lines at once.

Paper control switches

There are two switches located on the right side of your printer (Figure 2-2).These switches allow you to make certain adjustments to improve the print quality on your paper.

DENSITY switch — This switch makes the print lighter or darker. Move the switch toward the back of the printer to make the print lighter; move the switch toward the front of the printer to make it darker.
