Operation and Maintenance

Your LQ-1500is now set up. You’ve connected it to your computer and set the switches. Now you’re ready to learn how to use the controls and indicators on the printer to operate it correctly. We’ll also give you some advice on how to maintain your LQ-1500 and keep it printing smoothly for a long time.

Then, in Chapter 3, you’ll learn how to install and load the paper feeders which will give you an opportunity to use the controls discussed here.

Controls and Indicators

There are several controls and indicators on the LQ-1500 (see Figure 2-1). You use them to operate the printer and make your day-to-day printing easier for you. Here’s what these controls do:

The power switch

The power switch is located on the left side (toward the rear) of the printer. Press the front side of the switch to turn the printer ON; press the back side to turn it OFF.

The control panel

The control panel, located on top of the computer, has indicator lights and buttons which monitor the printing process. They are:

•POWER light -- glows green when the power is ON.

•READY light -- glows green when the printer is ready to accept data. The light flickers somewhat during transmission. This flick- ering is normal.
